doubleArray
- Two dimensional array holding audio samples.
For each channel, m, doubleArray[m] is a single dimensional
array containing samples for channel m. All channels are
required to have the same number of samples, but this is
not checked.playbackData
- An array into which to put the results, which
have bytes representing linear signed PCM big endian formatted
audio data.java.lang.IllegalArgumentException
- Not thrown in this base class.
