Is there a way to save .wav samples according to dedicated file size ?

Post by rickygai »

hi,

is there a way to save a sample .wav data based on the file size we set beside re-sampling the audio data ?

Something like the wavelength is shrunk like below:

Please advise.

Sorry, what?

That picture looks like the audio has been sped-up to play twice as fast. :?: That's easy to do and of course you do get a smaller file...

The file size is determined by the amount of data and the playing time. i.e. A regular uncompressed "CD quality" WAV file is 16-bits, 44.100 samples-per-second, and 2 channels. There are 8 bits in a byte so the file size is 2 Bytes x 44.1K x 2 channels = 176 KB per second. Or, that's a bit rate of 1411kbps.

With FLAC (lossless compression) you can cut the file size almost in half. With MP3 (lossy compression) you can get good quality at about 1/5th of the size (i.e 256 kbps) or smaller if you sacrifice quality.
