Audio File Size & Sample Rate
Compute uncompressed audio files size based on sample rate, bit depth, and duration.
PCM Format Parameters
- File size formula = Bitrate (bps) × duration (seconds) / 8 bytes/bit
- Multiplied by 1024 for standard system sizes. Uncompressed PCM represents maximum precision before lossless or lossy (e.g., MP3/FLAC) compression.
