API, OpenAPI and WebMCP documentation

Explanation

88.2kHz / 24-bit stereo streams 529200 bytes/second (0.5292 MB/s). MB = seconds x 0.5292. With input 1 s, result is 0.5292 MB.

Method & PCM Profile

Method basis: fixed PCM byte-rate estimate from sample rate, bit depth, and channel layout, then scaled by recording time at 0.5292 MB/s.
Profile reference: 88.2kHz / 24-bit stereo PCM Audio (529,200 bytes/s; 0.5292 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 seconds to mb?

Seconds to MB uses 88200 Hz, 24-bit depth, and 2 channels for this profile.

How is the 31.752 MB per minute factor calculated for 88.2kHz / 24-bit stereo?

Bytes per second = 88200 × (24 / 8) × 2 = 529200 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.5292 MB/s or 31.752 MB/min.

How do I reverse s to MB for 88.2kHz / 24-bit stereo?

Use the opposite route for 88.2kHz / 24-bit stereo to convert file size (mb) back to duration (seconds) with the same PCM assumptions.
