WAV uses raw PCM payload. MP3 is estimated from constant bitrate; real VBR encodes can differ.

About this calculation

WAV uses raw PCM payload. MP3 is estimated from constant bitrate; real VBR encodes can differ.

How to use this calculator

What to enter

Enter or select the following as requested: Duration (minutes); WAV sample rate; WAV bit depth; WAV channels; MP3 bitrate (kbps). Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The audio result calculates or estimates timing, pitch, tempo, frequency, bitrate, or storage from the sound and session settings entered. Check sample rate, bit depth, channel count, codec, tempo, beat unit, and whether latency is measured as a one-way or round-trip value.

When to use it

Use this when planning a recording, editing audio, syncing sound, or estimating media size. Actual results depend on the device, audio interface, codec, buffer settings, and project configuration, so verify critical timing or compatibility in the target setup.
