  • The contest
    What is a Mix contest ?
    A Mixing contest is launched by a musician with audio engineers registered on our platform in order to obtain the best audio mix for his music.
    The mixing step is performed after the recording of the tracks in the studio or home studio.
    What is a Mastering contest ?
    A Mastering contest is launched by a musician with audio engineers registered on our platform in order to obtain the best audio mastering for his music.
    The mastering step is performed on the result of the mix, it is the last step before the release of a song (digital or physical).
    What is a Mix + Mastering Contest ?
    A Mix + Mastering contest is launched by a musician with audio engineers registered on our platform in order to obtain the best mix + mastering for his music.
    Mixing + Mastering takes place after the tracks have been recorded in a studio or home-studio and allows you to reach the stage of releasing the song (digital or physical).
    During a Mix + Mastering contest, the musician's choice is based on the mastering submitted by the audio engineers.
    How does a contest work?
    A contest is divided into 3 phases:
    • Once the contest is launched by the musician, the Qualifications phase begins, at the end of which only 2 or 3 Finalists will be selected for the Final phase.
    • During the Finale phase Finalists may submit enhanced versions of their excerpts for the musician to determine a winner.
    • Once the winner has been determined, focus on the Finalization phase and the transmission of the final audio file. After validation by the musician, the winning audio engineer receives his reward.
    A timeline on the contest management page allows you to follow these steps (and learn from the tooltips):
    Contest timeline Contest timeline Contest timeline
    What is the Qualifications phase?
    During this phase, the musician listens and compares the different samples from the audio engineers (up to 2 revisions). If desired, a chat allows the Musician to chat with each of the participants (this option can be disabled by the musician when creating the contest).
    At the end of this phase, during a choice period the musician selects up to 3 finalists for the Final phase.
    What is the Final Phase?
    During this phase, up to 3 audio engineers (at least 1) are still in the running. They can send up to 2 revisions of their work as samples.
    At the end of this phase, during a choice period, the musician designates the contest winner.
    What is the Finalization phase?
    During this phase, the winning audio engineer and the musician refine the song. The audio engineer offers improved versions over the entire track, the number of final revisions is determined in advance when selecting the packby the musician.
    At the end of this phase, the winner sends the final file to the musician and the latter completes the contest to unlock payment for the work.
    What is a period of choice?
    During this period, which occurs at the end of each phase of the contest, the audio engineers are no longer allowed to send their samples, and the musician selects the participants who will move on to the next phase. The duration of these periods are defined by the musician when the contest is created.
    How long does a contest last?
    A contest has a variable duration according to the choices made by the musician during the creation of the contest:
    • The Qualifications phase lasts between 2 et 22 days.
    • The period of choice of finalists lasts between 1 et 3 days.
    • The Final phase lasts between 2 et 8 days.
    • The period of choice of the winner lasts between 1 et 3 days.
    • The duration of the Finalization phase is done according to the need of the musician.
    A contest lasts between 3 (Express contest) and 36 days (the Finalization phase does not have a fixed duration, it is excluded from the calculation).
    What is an Express contest ?
    An Express competition starts directly in the Final Phase (no limit on the number of participants), it allows the musician in a hurry to access the Finalization phase more quickly. Be careful, the shorter the contest, the less opportunity there is for audio engineers to participate.
    What is a Guaranteed contest?
    During a Guaranteed contest, the amount put into play by the musician must be paid. If no winner is chosen, the money goes to the finalists.
    What is a "One-to-one" contest ?
    The "One-to-One" contest allows a private and secure remote collaboration between a musician and an audio engineer chosen on our platform. When creating this contest, the musician selects an audio engineer from among the finalists of his previous contests, and send the invitation. The audio engineer is notified by email and has a given number of days (determined by the musician) to accept or decline the invitation. From the moment the audio engineer is invited, the chat with the musician is open to discuss the terms of the collaboration (start dates, end date, etc.).
    Once the contest has been accepted by the audio engineer, the musician proceeds with the payment and the collaboration then begins directly in the Finalization phase. If the invited audio engineer declines, the musician may invite another finalist to collaborate.
    A "One-to-One" contest is necessarily a guaranteed contest.
    What is a Rough Mix?
    A Rough Mix is an audio file that allows you to listen to the unprocessed song (export of recorded tracks for a mixing contest, result of a mix for a mastering contest or mix + mastering). It allows the audio engineers to get a preview of the song and appreciate the work they will have to do.
    What is a source file?
    The source file is a compressed file (ZIP or RAR) containing:
    • for a Mixing contest: all audio tracks in uncompressed format (WAV / AIFF - 16 bits / 44.1kHz minimum, 24 bits / 44.1kHz maximum - recommended).
    • for a mastering contest: the result of a mixing in uncompressed format (WAV / AIFF - 16 bits / 44.1kHz minimum, 24 bits / 44.1kHz maximum - recommended).
    • for a mix + mastering contest: all audio tracks in uncompressed format (WAV / AIFF - 16 bits / 44.1kHz minimum, 24 bits / 44.1kHz maximum - recommended).
    Don't hesitate to read the rules to prepare your tracks.
    What is an sample?
    The sample is an audio file on which the audio engineer has worked and which is submitted to the musician for his review. This is an sample of the song representing 40% of its total duration (3 minutes max), starting at a point in the song determined by the musician at the time of the contest's creation.
    What is the final file?
    The final file is a compressed file (ZIP or RAR) containing at least:
    • for a Mixing contest: the result of mixing in WAV / AIFF audio format - 24 bits / 44.1kHz.
    • for a Mastering contest: the result of mastering in audio format WAV / AIFF - 16 bits / 44.1kHz.
    • for a Mix + Mastering contest: the result of mixing in WAV / AIFF audio format - 24 bits / 44.1kHz and the same result mastered in audio format WAV / AIFF - 16 bits / 44.1kHz.
    It is possible, when creating the contest, that the musician also requests compressed versions of the song (MP3, AAC, etc.), or alternative versions (instrumental, etc.).
    What are the sound options of the contest?
    To help musicians clarify their expectations of audio engineers, Moja-audio offers them the opportunity to provide information, using a scale of values, on certain sound rendering preferences:
    • Artistic freedom : allows to specify the degree of freedom available to participants (artistic effects, arrangements, etc.).
    • Dynamic - Loud : lets you specify what is the goal to achieve for the final volume of the song. Dynamic: a song that breathes, Loud: a song that seeks to compete with the most important volumes of current music.
    • Natural - Processed : allows to direct the audio engineer to a rather "natural" or rather "processed" rendering.
    • Raw - spatial : allows to specify if the mood of the song must be rather raw (impression of proximity of the artist) or rather spatial (impression of depth and large dimension).
    What information can be found on the contest thumbnail?
    • 1 - New messages : number of unread messages.
    • 2 - New files : number of files not yet listened to or downloaded.
    • 3 - New participants : number of new participants.
    • 4 - contest type : mix, mastering or mix + mastering.
    • 5 - contest title : title of the contest given by the musician.
    • 6 - Name of the musician : username of the musician who created the contest.
    • 7 - Reward : € including VAT reward won by the contest winner.
    • 8 - contest state : actual state of the contest.
    • 9 - Remaining time : remaining time before the end of the current phase.
    • 10 - Number of participants : number of participants in the contest.
    What do the different colors of the contest thumbnail correspond to?
    There are 5 contest states:
    • drafting : the contest has been created by the musician, but is not yet launched (only the musician can see the contest).
      Contest in drafting state

    What do bronze, silver and gold medals mean?
    For an audio engineer:
    • a bronze medal is won each time he enters a contest and sends a sample
    • a silver medal is won each time he is qualified for the Final phase
    • a gold medal is won each time he is declared a contest winner
    Audio engineer's medals show his experience with Moja-Audio, as well as his ability to be a finalist or winner of a contest.
    For a musician:
    • a bronze medal is won each time he creates a contest
    • a silver medal is won each time he launches a contest
    • a gold medal is won each time he completes a contest
    The medals of a musician testify to his past experience on Moja-Audio, as well as his ability to go to the end of a contest.
    How to set email notifications for a contest?
    There are 4 types of notifications for a given contest (2 are only for musicians):
    • New message notifications : turn on these notifications to receive an email when you receive a new message. Each email contains the name of the user and his message in its entirety. (notifications disabled by default)
      Warning: remember to disable these notifications when you discuss via the chat, otherwise you may receive a large number of emails (setting directly accessible in the tab "chat").
    • Contest informations : activate these notifications to receive an email at the end of each phase, recalling the essential informations of the next phase and the actions to be taken by the users. For a musician, these notifications are always activated: the information received for his own contests by these mails are too important to be able to do without them.

    How much does a contest cost?
    The prices indicated in our packs (bronze, silver, gold or platinum), are in euros including VAT. They include: the reward paid to the winning audio engineer and the Moja-audio commission.
    To view our rates in detail, please visit the following page : our packs.
    Which pack to choose?
    For each type of contest, you can choose between 3 and 4 packs (bronze, silver, gold and platinum). Each pack corresponds to different needs.
    Your choice is then made according to the following criteria:
    • The number of stereo tracks in the song (only for mixing contests and mix + mastering)
    • The number of revisions included in Finalization phase
    • The reward awarded to the audio engineer (to attract the best participants)
    Can I mix or master an EP / album?
    An "EP/album" contest allows to get a mastering for a set of songs (from 2 to 25) in order to benefit from a homogeneous sound rendering on a multi-title project.
    The selection of the audio engineer is made on a single track called the "initial song": the musician makes this song available (by uploading it to the competition management page), the contest traditionally begins with a qualification phase, then a final phase at the end of which the musician designates the winner.
    Once the winner has been chosen, the musician must then send all the tracks to be mastered from the competition page in order to make them available to the audio engineer.
    The musician and the audio engineer proceed together to finalize the project song by song. Proposals are no longer made on samples but on the entirety of the songs and according to the number of revisions indicated in the pack.
    At the end of the contest, the audio engineer sends a.zip or.rar file containing all the versions requested by the musician, and the latter completes the contest in order to unlock the payment of the service.
    Can I run multiple contests at the same time?
    You can start several contests at the same time. On the other hand, you must make sure you have the availability to appreciate the different proposals of the audio engineers, and to communicate with them in order to obtain the best results.
    How to protect my work?
    See the article on our Blog.
    How is the payment of the service processed?
    The payment of the service comes at the launch of the contest (after the creation and sending of your tracks). It is made by credit card via our provider Mangopay (consult the Mangopay Terms).
    The payment of the reward to the winner audio engineer intervenes when you confirm the receipt of the final files and complete the contest.
    What is the "money back guarantee"?
    If you do not obtain satisfaction during Qualification phase, Moja-audio will reimburse your payment in full. (cf Terms).
    On the other hand, as soon as audio engineers are engaged in the next phase, the contest become a Guaranteed contest, reimbursement is no longer possible.
    Which payment method to use?
    The credit card (Visa, Mastercard) is the only accepted method of payment on the Moja-audio website.
    Who are the audio engineers present on the platform and how are they selected?
    Audio engineers wishing to join our community must first complete an invitation code request. A number of technical questions are then asked to judge their professional knowledge. After analyzing their answers, if they are validated, Moja-audio sends them a personal invitation code in order to create a "Audio engineer" account.
    Moja-audio also regularly and spontaneously offers invitation codes to professional audio engineers.
    Who will have access to my rough mix? my tracks?
    The rough mix and the tracks of your song can not be listened to or downloaded by a simple visitor of the site, nor the other musicians.
    Only audio engineers registered on our site can listen to your rough mix and only those participating in your contest can download the source tracks.
    Why make my choice on an sample?
    In order to protect the work done by audio engineers, the choice is made on an sample of 40% of the song (3 minutes max). This allows the audio engineers to preserve their work against any misuse by unscrupulous musicians.
    This sample, as representative as possible, is determined by you at the time of the contest creation.
    Can I collaborate live with a particular audio engineer?
    Moja-audio offers you the opportunity to launch "One-to-One" contests to collaborate with the audio engineer of your choice, among the finalists in your previous contests.
    How to prepare my tracks?
    Here are the basic rules to follow when preparing your tracks :
    • Clean your mix : send only the needed files. It's not the engineer's job to select the vocal take to be used in the song.
    • You have to export each channel as a .wav file or .aiff, 44.1 and preferably 24bit, starting at the beginning of the song and ending when the sound on this track ends, or all the way to the end.
    • Stereo tracks must be exported as stereo interleaved files, no need to export separate left/right tracks.
    • Your tracks must not clip (go over 0 level), please leave at least 6dB of "headroom" (dynamic range before the signal goes to 0dBFS)
    • Turn of your processing, unless they have an 'artistic" purpose : favorite guitare effect, autotune setting, etc.). Every other effects (compressor, EQ, reverb, etc.) must be turned off before export, and NO EFFECT must be on the stereo out bus !
    • Don't fade any of your tracks. If a fade must be done, it will be done on the entiere song.
    • If possible, label your tracks clearly (Kick, Lead Vocal, FX1, etc.). It will save time for all the engineers who will work on your song.
    • Maybe the most important : make sur the tracks are exported strarting at the same poinnt (0:00 or before), unless they won't be in sync. If they aren't it will be hard (even sometimes impossible) to correctly sync the tracks by hand.
    • Compress your files in a .zip or .rar file, with maximum compression ratio setting : the file will be lighter, so you'll need less time to send it, or others to download it.
    If you have any doubt about all theses rules, don't hesitate to contact us, we'll try to help you as much as we can.
    Can I ask audio engineers to edit or arrange my song?
    There is no rule on Moja-audio prohibiting this request. That said, editing and arranging are not the core business of the audio engineer, and our platform is not dedicated to editing and arranging. Such an objective could require many revisions because any opinion is completely subjective (this is a 100% artistic approach).
    How to eliminate a participant?
    To disqualify a participant, go to the management page of your contest, in the "Participants" tab. From the thumbnail of the participant concerned, click on the "Ignore" button. This will have the effect of graying the thumbnail and placing it at the end of the list. This action is reversible until the end of the period of choice.

    Can I edit my contest information?
    As long as your contest is not launched, it is in the creation phase. You can make any changes you want. When your contest is launched with our audio engineers community, you will not be able to edit it.
    If necessary, you will be able to clarify some informations to the participants using a message send to everyone (from the contest management page).
    How to communicate with participants?
    You may at any time send the same message to all participants in your contest by using the "send message to all" button (from the contest Management page).

  • I am an audio engineer
    Why is an Invitation Code required to register as an audio engineer on Moja-audio?
    Moja-audio wishes to offer musicians the assurance that their song will be heard and downloaded only by serious users, ready to enter the contests. We do not want to give free access to their original compositions.
    That's why we select as rigorously as possible the people who register as audio engineers on our platform.
    How to register as an audio engineer?
    Registration on the Moja-audio platform is selective and takes place via an invitation code. This code can be sent to you directly by email by our commercial teams after census of your professional activity.
    You can also get this code after completing our registration request form.
    What is a Premium Account?
    Premium account offers you more possibilities and features that a classic account :
    • participate in more than 3 contests per month
    • listen to samples from other participants (if you're not qualified for the next phase)
    • access to Premium Account contests
    You choose the duration of your subscription, there is no automatic renewal. You will receive an email a few days before the end of your subscription to signify that it will stop soon.
    To subscribe, go to your "Profile" area, "Premium Account" tab.
    How much will my final payment be?
    You will find the amount of your final remuneration in euros including VAT on the thumbnail of each contest. The commission of Moja-audio is taken upstream, on the amount paid by the musician.
    When and how will I be paid?
    Only the contest Winning engineer receives the contest Reward. It is important to enter your banking information in order to collect it. To do this, go to your "Profile" section, "banking information" tab and complete the required fields.
    The payment of the Reward comes after the sending of the final file to the musician and after the closing of the contest by the latter. This action then triggers a transfer of the Reward to your bank account (within 48 hours).
    How to be kept informed of new contests?
    In the "Profile" area, there is a "Notifications" tab. You will find the section "Notifications by mail of a new contest". Three options are available to you:
    • « Alert me for any new contest launched » : You will receive an email summarizing the essential information of the contest (Type, Name, Award, etc.), for each new contest launched.
    • « Alert me only according to the following criteria » : you will receive an e-mail summarizing the essential information of the contest (Type, Name, reward, etc.), with each new contest launched responding to the (multiple) choices made in the options offered:
      • Contest type (Mixing, Mastering, etc.)
      • Musical style
      • Minimum reward
    • « Do not alert me » : you never receive an email about the launch of a new contest. (option enabled by default)
    What is it to be "interested" in a contest?
    When you enter a contest page that you do not participate in, there are two choices: "participate" or "interested".
    Clicking "Interested" allows you to easily find the contests that interest you on your "My contests" page, without engaging you.
    What do I have to do to participate in a contest?
    When you enter a contest, you have access to the musician's original tracks. This is a strong act of trust that is shown to you. You must therefore be worthy of it, in other words, you must actively participate in the contest as long as you are qualified (send samples properly worked, communicate with the musician, etc.).
    Any repeated failure, after a first warning on our part, to this rule (no sample sent, sample reported by the musician as not corresponding to its tracks, tracks not processed, refusal of communication, etc.), will result in the termination the audio engineer's account and the ban of his IP address, surname and first names.
    What rules should I follow when sending a sample?
    Apart from the obvious rules (send the file corresponding to the piece, send a processed sample, etc.), the only rule that must be carefully considered is respecting the duration and position of the sample in the song. Indeed, when creating a contest, the musician determines when to start the sample, and Moja-audio determines the duration (about 40% of the total duration of the song - 3 minutes max). This choice of the musician is important because it allows him to include in the sample the most significant sections to be able to appreciate your work.
    Respecting the duration of the sample protects you, as it would prevent an unscrupulous musician from using your work without you winning the contest.
    For mixing contests only, you must conform the perceived volume ("loudness") to -16 LUFS Integrated (ITU-R BS.1770-4 standard), at +/- 1 LUFS. Indeed, it is very difficult to compare mixes that do not have a homogeneous sound level, so normalizing the perceived sound level allows the musician to choose more serenely. In our opinion, this precaution is not necessary for mastering contests, because the final perceived sound volume is one of the criteria on which a musician can base his choice. To help youself, you can use the free version of the plugin Youlean® Loudness Meter.
    How to best meet the expectations of the musician?
    In order to put the odds on your side, and best meet the expectations of musicians, it is essential to craefully read the information given by the latter in the contest page: the general description, the intended use, the references, but also audio options and additional technical information.
    Do not hesitate to ask your questions to the musician via our chat, during the Qualifications phase or the Final phase.
