PCM and WAV both format contains raw PCM data, the only difference is their header (wav contains a header where pcm doesn't). So if you just add wav header then it will do the tricks. Just get the PCM data and add the wav header on top of the PCM data. To add wav header with PCM data, …

SpletPulse-code modulation (PCM) is a method used to digitally represent sampled analog signals.It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value … SpletThe idea is: open the file in binary mode. read enough from the file to determine that the file has a wave header. make sure that the wav header indicates that the content is PCM. from the wav header, determine how many channels are present, the number of bytes per channel, the number of bits per sample, the sample rate.
