System object: dsp.AudioFileWriter
Write one frame of audio output samples
step(H,AUDIO) writes one frame of audio samples, AUDIO , to the output file. AUDIO is either a vector or an M-by-N matrix for mono or N-channel audio inputs respectively.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
