Wav file size calculation formula

Hi Kurt

Here is the wav file calculation formula you need. Size=sample rate*number of channels*(bits per sample/8)*times in second.

Example: A 44.1hHz , stereo 16 bit wav file lasting 60 seconds.

Size=(44.1*2*(16/8*60)1024

Size=10.3359 MB

Wav file size calculation formula

The size of Wav file will depend upon the pace at which it is being sampled and the duration of the file. Hence, if the duration of a file is long, the size of the file will be bigger as well. Secondly, a mono and stereo tell you the channels. As Channels are increasing the file size will also increase. In simple words, a mono file will require half as space as a stereo file.

Basic Formula for File size for WAV file would be

Bitrate*Duration/8 bytes

ie (bits/sample*samples/second*channels)*Duration bits.
