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