- For compatibility with pre-v7 Windows Media Players, use the 'Windows Media Audio 4' format. For better quality, use the newer 'Windows Media Audio 9' format. For the latter this program supports both 'CBR' (2-pass constant bit-rate), 'ABR' (2-pass average bit-rate) and 'VBR' (1-pass quality based variable bit-rate) encoding. For voice recordings you can also get a high compression using the 'Windows Media Audio 9 Voice' format. All the previous formats are 16-bits per sample. There is also a 'Windows Media Audio 9 Lossless' format that allows bit-exact reproduction of 44100 or 48000 Hz stereo data at either 16 or 24-bits per sample. The 'Windows Media Audio 9 Professional'(listed as Pro CBR, Pro ABR, and Pro VBR) is like the normal WMA 9 formats but 24-bits per sample and up to 96kHz sample rate.
- You can also read the audio portion of .ASF (Active Streaming Format) and .WMV (Windows Media Video) video clips.
