Audio Bitrate Calculator
Works out the bitrate of WAV-style audio, or the real average of a file you have.
Uncompressed bitrate
— kbit/s

Uncompressed size per minute —
Average bitrate of the file — kbit/s
File compared with uncompressed — %
The formula
uncompressed = sample rate × bit depth × channels average = size × 8 ÷ length
Compressed formats such as MP3 choose their bitrate, so only the uncompressed figure follows from the sample rate.
What to watch out for
WAV and AIFF hold uncompressed audio, so the first figure applies directly. FLAC usually comes to less, because it compresses without losing anything.
