Audio File Upload Instructions

Please Read

  • Make sure that you have listened to your mix several times and that you are happy with its
    present state.
  • Be aware that incorrect level differences between separate instruments (or parts) including
    vocals, are too difficult and sometimes impossible to fix during mastering.
  • Not even the best mastering tools in the world will turn a bad mix into a great one. So, if the sound of the mix doesn’t stand already on its own, that’s a telltale sign that your music won’t benefit very much from the mastering process.


B- Next, check levels:

Make sure your signal has NO DISTORTION & make sure your output levels are not peaking too high (not loud, please)!

  1. The stereo signal on the left, peaks at about -12dB and has plenty of headroom (PML) for us to do
    our ‘magic’.
  2. The stereo signal peaks at 0dB, it doesn’t clip, but there is hardly any headroom for us to work with. Mastering benefits maybe limited.
  3. The worst case scenario, the stereo signal peaks at above -0dB and clips the meter. We may still be able to work with it, (i.e. paid orders) but, that’s not ideal for professional mastering, especially if what we’re looking at is not *peak* but average sum levels, which could possibly mean that there is too
    much clipping and distortion. We don’t recommend you submit mixes like that. But, if you still do this, expect the overall loudness to be the same, that is, if we accept it. Most likely, it will be declined for being too loud for our demonstration purpose.   

TIP: Bounce your music again and lower the stereo master output so that the highest peak does not exceed -3dB.  Sometimes by simply bypassing any peak limiters, or maximizers like: L1, L2, TC Waves Finalizer, etc, the problem is solved.


C- Check Audio format:

  • Stereo mixes delivered as two-channel mono, split stereo, or stereo interleaved files (preferred).
  • Resolutions accepted: 32, 24 and 16 bit.
  • Sampling rates accepted: 192, 96, 88.2, 48 and 44.1 kHz (CD quality) which is preferred.
  • File Types: we prefer WAV, but accept the AIFF and SDII formats.
  • Be aware that the higher the resolution and sampling rate, the longer the upload time (between
    2 to 10 minutes each song depending on your connection speed).
  • MP3 is a lossy and compressed file and thus, not ideal for mastering. If you want to supply
    us with MP3 files anyway, please make sure that they are coded at least 192 Kbit/sec (stereo) and at 44.1 kHz.


D- File Names:

  • Do not upload music with generic file names, e.g., files named: ‘TRK01-‘, ‘Track-1’, or
    ‘Song 1’, etc.
  • Files not properly named are not good for our upload script as they may get deleted by mistake.
  • We prefer you rename your files with your full name and to also match the title, or part
    of the title name of the mix you are submitting for processing (e.g., john_doe_mysong.wav).
