The wonderful thing about standards is that there are so many of them. Here are the audio formats I use on a regular basis.
• Full quality: Broadcast WAV, AIFF, Sound Designer II, FLAC
• Data reduced: AAC, MP3
Bit depth: 24, 16
Sample rate (kHz): 44.1, 48, 88.2, 96
I use Digital Performer in my studio, and here is the entire list of compatible audio formats the software can handle. Please note that while DP can master in multi-channel, I specialize in creating final mixes in two-channel stereo.
