void NNS_SndPlayerSetAllocatableChannel( int playerNo, u32 chBitFlag );
The allocatable channel is configured by sequence that plays back on the designated player. The default is 0, which allows for unlimited allocation.
chBitFlag
configures the allocatable channel with a bit flag. Shows channel 0, channel 1, channel 2, etc. in order from the lowest bit, and only allows for allocation from channels that have set bits. There are no limitations where the value is 0, and allocation can be performed from all channels.
There are 16 channels. The features of the channels differ depending on the channel number, as indicated below:
Table: Channel Numbers and Functionality
Channel Number | Function |
---|---|
0, 2 | Can playback PCM/ADPCM. Output from these channels can also be used for sound capture input. |
1, 3 | Can playback PCM/ADPCM. Because sound capture and the timer are shared, these channels can be used only for sound capture output when sound capture is used. |
4 ~ 7 | Can playback PCM/ADPCM. These channels are used preferentially when playing back waveform data on sequence playback. |
8 ~ 13 | Can playback PCM/ADPCM and PSG rectangular waveforms. |
14, 15 | Can playback PCM/ADPCM and white noise. |
This function is called inside of the NNS_SndArcPlayerSetup
function. If this function is called again, the set values will be overwritten.
By calling the NNS_SndPlayerSetTrackAllocatableChannel for the sequence that was played back, the values that were configured here are overwritten.
