Estimate audio file size in MB / GB from sample rate, bit depth, channels and duration. Compare WAV, AIFF, FLAC and lossy formats.
| Format | Compression | File size | Bitrate (kbps) |
|---|
Uncompressed PCM size = sample rate × bit depth × channels × duration / 8 bytes. FLAC averages ~55% of PCM (varies with material); MP3 320 and AAC 256 are constant-bitrate estimates.
Bitrate = sample rate × bit depth × channels, in bits per second.
