Audio can be submitted as WAV, BWAV, AIF & SD2 at whatever sample rate you have been mixing at and 24bit or 32bit. Best results are usually achieved from high quality resolutions. We would prefer submitted tracks to have a minimum of 3dB of headroom, so a peaklevel of -3dBfs. If your track is already maximized, heavily limited/compressed and loud then we will have very little acoustic space to work with. Some mix-buss compression/limiting is ok. Please label your tracks clearly and include the track number if part of an EP or Album. Tracks can be sent via FTP using Rapidshare. We have used Rapidshare with good results, for faster uploads and downloads register for a free rapidshare account (10Gb).
