As others have pointed out, there's metadata in the wav file, but I think your question may be, specifically, what do the bytes of data, not metadata mean? If that's true, the bytes represent the value of the signal that was recorded.
What does that mean? Well, if you extract the two bytes say that represent each sample assume a mono recording, meaning only one channel of sound was recorded , then you've got a bit value. In WAV, bit is always? I suppose your question is "What do the bytes in data block of. Prelude : Let us say we play a 5KHz sine wave using some device and record it in a file called 'sine.
Now you already know what the header in that file represents. Let us go through some important definitions:. Now coming to the answer of your question: It is not possible practically to write the whole sine wave to the file because there are infinite points on a sine wave. Instead, we fix a sampling rate and start sampling the wave at those intervals and record the amplitudes.
The sampling rate is chosen such that the signal can be reconstructed with minimal distortion, using the samples we are going to take. The distortion in the reconstructed signal because of the insufficient number of samples is called 'aliasing'. To avoid aliasing, the sampling rate is chosen to be more than twice the frequency of our sine wave 5kHz This is called 'sampling theorem' and the rate twice the frequency is called 'nyquist rate'.
Thus we decide to go with sampling rate of 12kHz which means we will sample our sine wave, times in one second.
We take these values and put it in an array. Then we create the proper header to reflect our metadata and then we convert these samples, which we have noted in decimal, to their hexadecimal equivalents. These values are then written in the data bytes of our. Two bit audio wouldn't sound very good : Most commonly, they represent sample values as bit signed numbers that represent the audio waveform sampled at a frequency such as How are we doing?

Add a comment. This is a common method Windows uses for storing audio and video files— like AVI— but can be used for arbitrary data as well.
WAV files are generally going to be much larger than other popular audio file types, like MP3, due to the fact they are typically uncompressed compression is supported, though. Windows and macOS users can play WAV files right out of the box without having to install any third-party software. In macOS, they play by default in iTunes. All you have to do is double-click on the WAV file, and your default audio player will open the file and start playing.
If, however, you prefer a different audio player than either of those, changing the association of a file is a simple process on either Windows or macOS. When you install a new music app, the chances are that the new app will be able to claim the association with WAV files during installation.
