Checklist

Please send us .wav or .aif files. Resolution should be 44.1 kHz/24bit or higher.
Leave enough headroom and if you use compression on the sum, please do not overcompress it. And of course no limiter on the mixbus.
Label your tracks with artist, trackname, samplerate
We recommend to name or send us reference files. It makes the work easier for both sides to find out what kind of sound you are looking for.
