/**
* 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.
