Single byte(8 bit) audio is not used in professional audio recording and it is char type range from 0….255 Usually, the PCM format sound file will use single(8 bit), two(16 bit), three, or four byte’s sample’s to represent the sample’s How many bits(or) bytes used in Audio data for encoding each sample

There are different types of digital encoding some use compress data other use uncompressed data but the most popular encoding is PCM(Pulse Code Modulation) Sample precision Sound files provide a platform for computer’s to manipulate audio by music signal processing, without worrying complex task such as ADC/DAC Digital Encoding

Hi there, do you know? What is a wav file? And the wav file format? I am using c/c++ to explain theaudio file format in full detail Sound storage in computer files
