MB to seconds for 48kHz / 24-bit stereo PCM Audio

Methodology·How We Verify

Snapshot

At 48kHz / 24-bit stereo PCM, 100 MB stores about 347.2 seconds of audio.

Reference basis: This result uses the fixed 48khz / 24-bit stereo pcm audio PCM profile to turn storage budget back into recording time from 288,000 bytes/s.
Example: For 10 MB, the 48kHz / 24-bit stereo PCM Audio PCM estimate gives about 34.7 seconds of recording time.

API, OpenAPI and WebMCP documentation

Explanation

48kHz / 24-bit stereo streams 288000 bytes/second (0.288 MB/s). seconds = MB / 0.288. With input 1 MB, result is 3.47222222222 s.

Method & PCM Profile

Method basis: fixed PCM byte-rate estimate inverted to recover recording time from storage size at 0.288 MB/s.
Profile reference: 48kHz / 24-bit stereo PCM Audio (288,000 bytes/s; 0.288 MB/s PCM basis).
Consistency rule: snapshot, calculator, FAQ, and common-value rows all use the same fixed PCM profile and byte-rate estimate for this route.

Questions & answers

Frequently Asked Questions

Which PCM settings are fixed for mb to seconds?

MB to seconds uses 48000 Hz, 24-bit depth, and 2 channels for this profile.

How is the 17.28 MB per minute factor calculated for 48kHz / 24-bit stereo?

Bytes per second = 48000 × (24 / 8) × 2 = 288000 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.288 MB/s or 17.28 MB/min.

How do I reverse MB to s for 48kHz / 24-bit stereo?

Use the opposite route for 48kHz / 24-bit stereo to convert duration (seconds) back to file size (mb) with the same PCM assumptions.
