What audio formats are acceptable?
We much prefer the following file formats:
- AIFF (.aif)
- Wave (.wav)
- Broadcast Wave (.bwf)
We can also accept Sound Designer II (.sd2) files.
We would strongly advise against mp3/mp4/aac or any other data compression system: however good you may think these sound, they do compromise the quality of your music. It may be a lot slower to transfer a .wav file but it is much better quality.
If for any reason the only version you have is mp3, do not convert that back to AIFF or WAV to upload, we probably have better algorithms for conversion and can produce the optimum conversion for you.
All mixes should be final ‘consolidated’ files, not a multitrack Logic or ProTools Session and all should be interleaved (not separate left and right files). Any of these files can be either uploaded to our server or shipped to us on write once discs (CDRs / DVDRs) or as CD Audio discs or DAT Tapes. We are not prepared to accept hard drives or 1/2” or 1/4” analogue masters for the iMaster service, however we will accept digital masters on DAT.
Please note: when saving your files, please make sure they are saved with a file extension, i.e. track.wav
Our system will accept files with the following file extensions:
- .aac
- .aif
- .aifc
- .aiff
- .jam
- .mp3
- .mp4
- .rar
- .sd2
- .sd2f
- .sit
- .wav
- .zip
