API, OpenAPI and WebMCP documentation

Explanation

48kHz / 24-bit 5.1 streams 864000 bytes/second (0.864 MB/s). GB = (hours x 3600 x 0.864) / 1000. With input 1 h, result is 3.1104 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 0.864 MB/s.
Profile reference: 48kHz / 24-bit 5.1 PCM Audio (864,000 bytes/s; 0.864 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 hours to gb?

Hours to GB uses 48000 Hz, 24-bit depth, and 6 channels for this profile.

How is the 51.84 MB per minute factor calculated for 48kHz / 24-bit 5.1?

Bytes per second = 48000 × (24 / 8) × 6 = 864000 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.864 MB/s or 51.84 MB/min.

How do I reverse h to GB for 48kHz / 24-bit 5.1?

Use the opposite route for 48kHz / 24-bit 5.1 to convert file size (gb) back to duration (hours) with the same PCM assumptions.
