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