inlineoverridevirtual |
Writes a set of samples to the audio stream.
Note that if you're trying to write the contents of an AudioBuffer, you can use writeFromAudioSampleBuffer().
samplesToWrite | an array of arrays containing the sample data for each channel to write. This is a zero-terminated array of arrays, and can contain a different number of channels than the actual stream uses, and the writer should do its best to cope with this. If the format is fixed-point, each channel will be formatted as an array of signed integers using the full 32-bit range -0x80000000 to 0x7fffffff, regardless of the source's bit-depth. If it is a floating-point format, you should treat the arrays as arrays of floats, and just cast it to an (int**) to pass it into the method. |
numSamples | the number of samples to write |
