Kirikiri's sound system can play Wave (PCM).
　Wave playback can be performed simultaneously, multiple streams can be played (playing long sounds while reading them little by little), and seamless loop playback using a sound loop information file (.sli file) that does not make you feel like a second stop (The sound loop information file is created with the loop tuner).

　WaveSoundBuffer can play standard uncompressed RIFF Wave format (extension is .wav, Windows standard format). The accepted formats are as follows.

• WAVE_FORMAT_PCM format, integer PCM between 8 bits and 32 bits, with 1 (monaural), 2 (stereo), 4 (quadraphonic), 6 (5.1ch) channels
• WAVE_FORMAT_IEEE_FLOAT format, 32-bit floating point number PCM with 1 (monaural), 2 (stereo), 4 (quadraphonic), 6 (5.1ch) channels
• WAVE_FORMAT_EXTENSIBLE format, subtype KSDATAFORMAT_SUBTYPE_PCM format, integer between 8 and 32 bits PCM
• WAVE_FORMAT_EXTENSIBLE format, subtype KSDATAFORMAT_SUBTYPE_IEEE_FLOAT format, 32-bit floating point PCM

　The formats playable by WaveSoundBuffer can be extended by plugins.

　WAVE_FORMAT_EXTENSIBLE has information on "Which channel is assigned to which speaker" in the data, but WAVE_FORMAT_PCM and WAVE_FORMAT_IEEE_FLOAT do not have this information. When Kirikiri handles 4ch or 6ch data with WAVE_FORMAT_PCM or WAVE_FORMAT_IEEE_FLOAT, it is interpreted as follows.

For 4ch

From the beginning of the channel, it is assumed that the data is for the front left, front right, rear left, and rear right speakers, respectively.

For 6ch

From the beginning of the channel, it is regarded as the data for the front left, front center, front right, back left, back right, and low frequency speakers, respectively.

The same rules apply when playing 4ch or 6ch sound with OggVorbis.
