Hours to GB for 48kHz / 24-bit mono PCM Audio

Methodology·How We Verify

Snapshot

At 48kHz / 24-bit mono PCM, 6 hours of audio needs about 3.11 GB.

Reference basis: This result uses the fixed 48khz / 24-bit mono pcm audio PCM profile, anchored to 144,000 bytes/s.
Example: For 1 hour, the 48kHz / 24-bit mono PCM Audio PCM estimate needs about 0.52 GB.

API, OpenAPI and WebMCP documentation

Explanation

48kHz / 24-bit mono streams 144000 bytes/second (0.144 MB/s). GB = (hours x 3600 x 0.144) / 1000. With input 1 h, result is 0.5184 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 0.144 MB/s.
Profile reference: 48kHz / 24-bit mono PCM Audio (144,000 bytes/s; 0.144 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 1 channels for this profile.

How is the 8.64 MB per minute factor calculated for 48kHz / 24-bit mono?

Bytes per second = 48000 × (24 / 8) × 1 = 144000 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.144 MB/s or 8.64 MB/min.

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

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