Sample Master

Thank you for using 48 Hour Masters

How It Works – Submitting A  Sample Master
1 – Check to see if your music file meets standards listed below
2 – Upload your master sample in the dropbox below
3 – 48 Hour Masters will send a part of a sample master of your song via upload back to you
4 – If you like our mastered sample, make full payment for one song, and rest of your complete track will sent to you via upload

Here is a list of requirements to check if your track is suitable for mastering:

  • Stereo WAV or AIFF file
  • 44.1 or 48 kHz / 16 or 24 bit quality
  • No compression, limiting or maximization on master output
  • 3 – 6 dB of headroom

Will you accept tracks as mp3?
Compressed formats such as mp3, mp4 or wma do not make good candidates for mastering, please avoid these formats if you can.
