uint8  val 
) [private]

void OPL::DOSBox::OPL::generateSamples ( int16 buffer,
int  numSamples 
) [protected, virtual]

Read up to 'length' samples.

Data will be in native endianess, 16 bit per sample, signed. For stereo OPL, buffer will be filled with interleaved left and right channel samples, starting with a left sample. Furthermore, the samples in the left and right are summed up. So if you request 4 samples from a stereo OPL, you will get a total of two left channel and two right channel samples.

Implements OPL::EmulatedOPL.
