Delivery and Preparation tips

This page contains some helpful tips for mixing and producing well prepared material for mastering, along with information on the formats that we accept at GSM and on the details GSM needs from our clients.

  1. 24Bit/32Bit (float) & 44.1 KHz or higher in AIFF or WAV format (no data compression!).

  2. Never up or down sample anything.

  3. Don’t use dithering.

  4. Don’t use limiting or normalization on the master-bus or final mix!

  5. Only use compressors, equalizers and exciters if you know what you’re doing and use them only for their vibe and character. Never use them for corrections or volume and dynamic adjustments! Leave this to the mastering engineer.

  6. Don’t do fade-ins and fade-outs at the beginning and end of a song. Just let your mastering engineer know what you’d prefer.

  7. All songs should approx. have 2 seconds ‘silence’ at the beginning and the end.

  8. Minimal peak headroom of -3 dBFS. Maximal peak not more than -2 dBFS

  9. GSM prefers to receive your material on the FTP server. GSM provides you with the upload details. In case of delivering on CDR/DVD: burn the songs as data and not as audio. Burn on the lowest speed possible and only use the best quality CDR/DVD you can find.
