| michael@0 | 12 | * The decoder implementation is currently limited to Linear PCM encoded |
| michael@0 | 13 | * audio data with one or two channels of 8- or 16-bit samples at sample |
| michael@0 | 14 | * rates from 100 Hz to 96 kHz. The number of channels is limited by what |
| michael@0 | 15 | * the audio backend (via AudioStream) currently supports. The supported |
| michael@0 | 16 | * sample rate is artificially limited to arbitrarily selected sane values. |
| michael@0 | 17 | * Support for additional channels (and other new features) would |
| michael@0 | 18 | * require extending WaveDecoder to support parsing the newer |
| michael@0 | 19 | * WAVE_FORMAT_EXTENSIBLE chunk format. |
