How to Use the Audio Bitrate & File Size Calculator
-
1
Enter the audio duration in hours, minutes, and seconds.
-
2
Select an audio preset (e.g. 320kbps MP3, 24-bit 96kHz FLAC, CD 16-bit 44.1kHz WAV) or set custom parameters.
-
3
Inspect the computed file sizes for uncompressed PCM, lossy MP3/AAC, and lossless FLAC.
-
4
Review hourly data consumption metrics for streaming and podcast hosting bandwidth planning.
Practical Example & Use Case
Estimating how much disk space a 2-hour multi-track 24-bit 48kHz live concert recording will require before starting the recording session.
Technical Notes & Limitations
Calculates theoretical payload size excluding container metadata headers.
