What format should I send my track in?

WAV or AIFF please.
Uncompressed stereo with a bit depth of at least 16bit, ideally 24bit and a sampling frequency of 44.1kHz up to 96kHz. No pre-processing using limiting or normalising – we need as much headroom as possible (between -6dB to -3dB is a good guide) to work with to make sure that your tracks sound as good as possible when we master it.

Please note Track duration must be no longer than 10 minutes.
Each version or mix of a track will be charged separately.
