What are the values in a WAV file?

The 16 bit values in the wav file are amplitude values, encoded as signed 16 bit numbers. The amplitude can go from -32768 to +32767. The value can often better be interpreted as (almost) -1.0 to +1.0, but this is an interpretation.

How many samples are in a WAV file?

Typically, they have 1 (mono) or 2 (for stereo). The data of a WAV file is given as a sequence of frames. A frame consists of samples. There is one sample per channel, per frame.

How do I know the sampling rate of a WAV file?

How do I find the sample rate of a WAV file? Find a WAV file's sample rate in Windows by right-clicking the file, then clicking “Properties.” In the window that appears, look under “Audio Format” for a set of details including a number expressed in kilohertz (kHz): This is the sample rate.

What is the encoding of WAV file?

Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed audio in the linear pulse-code modulation (LPCM) format. LPCM is also the standard audio coding format for audio CDs, which store two-channel LPCM audio sampled at 44.1 kHz with 16 bits per sample.
