Audio Length Estimator

Calculate uncompressed PCM audio duration based on file size and sample rate.

JavaScript Disabled: This calculator requires JavaScript to process inputs interactively.

Manual Calculation Formula:
Bytes per second = Sample Rate * (Bit Depth / 8) * Channels
Duration (seconds) = Total Bytes / Bytes per second

Estimated Duration

Assumes uncompressed PCM format (like .WAV). Lossy formats like MP3 cannot be calculated this way.
