Work out bit rate instantly with clear inputs, formula shown and shareable results.
Uncompressed bit rate is sample rate times bit depth times channels. CD audio is 44,100 x 16 x 2 = 1,411 kbit/s, and file size is simply that rate times duration divided by eight to get bytes.
Bit rate
bit rate = sample rate x bit depth x channels; bytes = bit rate x seconds / 8
Lossy codecs quote their own constant or average bit rate, typically 128-320 kbit/s, which is a fraction of the uncompressed figure.
Yes for uncompressed PCM. In practice many systems store 24-bit samples in 32-bit words, making it twice the size of 16-bit.
