5 Final Things To Remember:

1 Remember, a good mix will produce a great master.

2 Do not make your final mix levels too loud. 6-to -10 dbfs will work in most cases.

3 Do NOT put a processor or plug-in (ie compressor/limiter) across the Master Bus

4 Try not to master mp3,mp4/ aac. These are compressed audio files that are lower in quality. You want to deliver your master formatted to offer the best quality. We advise to use 24 bit 44.1K  AIFF or Wav files. Bwf and SD2 are also ok. We can also work with final mix audio copies from cds however, these are 16 bit by default.. Usable, but not the best format.

5 Including a song reference of a cd that you like is always a great idea and helps us to pinpoint what you want your finished master to sound like.

Remember, a great mix will produce a great master. Spend the necessary time it takes to get your mix right before the final mastering process.


What audio formats are acceptable?

All mixes should be final stereo 2 track audio files

DO NOT SEND SESSION FILES. No Logic or ProTools Sessions with seperate stems.

All files should be interleaved (not separate left and right files).


Please note: when saving your files, please make sure they are saved with a file extension, i.e. trackname.wav
