<strong>VS1003</strong>8 FUNCTIONAL DESCRIPTION8.2.2 Supported WMA FormatsWindows Media Audio codec versions 2, 7, 8, and 9 are supported. All WMA profiles (L1, L2,and L3) are supported. Previously streams were separated into Classes 1, 2a, 2b, and 3. WMA9 Professional and WMA 9 Lossless are not supported. The decoder has passed Microsoft’sconformance testing program.WMA 4.0 / 4.1:SamplerateBitrate / kbit/s/ Hz 5 6 8 10 12 16 20 22 32 40 48 64 80 96 128 160 192WMA 7:8000 + + + +11025 + +16000 + + + +22050 + + + +32000 + + + + + +44100 + + + + + + +48000 + +SamplerateBitrate / kbit/s/ Hz 5 6 8 10 12 16 20 22 32 40 48 64 80 96 128 160 192WMA 8:8000 + + + +11025 + +16000 + + + +22050 + + + +32000 + + + +44100 + + + + + + + +48000 + +SamplerateBitrate / kbit/s/ Hz 5 6 8 10 12 16 20 22 32 40 48 64 80 96 128 160 192WMA 9:8000 + + + +11025 + +16000 + + + +22050 + + + +32000 + + + +44100 + + + + + + + +48000 + + +SamplerateBitrate / kbit/s/ Hz 5 6 8 10 12 16 20 22 32 40 48 64 80 96 128 160 192 256 3208000 + + + +11025 + +16000 + + + +22050 + + + +32000 + + + +44100 + + + + + + + + + + +48000 + + + + +In addition to these expected WMA decoding profiles, all other bitrate and samplerate combinationsare supported, including variable bitrate WMA streams. Note that WMA does notconsume the bitstream as evenly as MP3, so you need a higher peak transfer capability forclean playback at the same bitrate.Version: 1.06, 2012-03-16 24
