WAV is the container format for the PCM codec so if you MUST have PCM then get into a binary file editor (wxHexEditor is a nice one) and delete the first 44 bytes (its header) of that WAV file. So above gives you 8000 samples per second and a bit depth of 8 bits, and mono. verify this using. avprobe some_video_audio_file.wav.

Delta modulation is a form of PCM audio that uses one bit per sample. In telephony, a standard audio signal for a single phone call is encoded as 8,000 analog samples/sec, 8 bits each, giving a 64 kbps digital signal known as the DS0 signal.

First generate the RAW file (in audacity, there is an option to export to headerless RAW audio file under Export -> Export Audio). Make sure you export to 8-bit signed or unsigned values. Then, using a linux tool called xxd, you convert the binary file into a c header file(I suppose you could do this with any hex viewer but I haven't tried).

Each segment has 16 8-bit PCM codewords assigned. These are the codewords that identify the voltage level of a sample at some moment in time. Each codeword, often called a PCM “word”, consists of 8 bits. The first bit (most significant bit) tells the distant-end receiver if the sample is a positive or negative voltage.
