API, OpenAPI and WebMCP documentation

Explanation

192kHz / 32-bit mono streams 768000 bytes/second (0.768 MB/s). GB = (minutes x 60 x 0.768) / 1000. With input 1 min, result is 0.04608 GB.

Method & PCM Profile

Method basis: fixed PCM byte-rate estimate from sample rate, bit depth, and channel layout, then scaled by recording time at 0.768 MB/s.
Profile reference: 192kHz / 32-bit mono PCM Audio (768,000 bytes/s; 0.768 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 minutes to gb?

Minutes to GB uses 192000 Hz, 32-bit depth, and 1 channels for this profile.

How is the 46.08 MB per minute factor calculated for 192kHz / 32-bit mono?

Bytes per second = 192000 × (32 / 8) × 1 = 768000 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.768 MB/s or 46.08 MB/min.

How do I reverse min to GB for 192kHz / 32-bit mono?

Use the opposite route for 192kHz / 32-bit mono to convert file size (gb) back to duration (minutes) with the same PCM assumptions.
