Audio File SizeGigabytes to Minutes At 48khz 24bit Mono

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

Methodology·How We Verify

Snapshot

At 48kHz / 24-bit mono PCM, 16 GB stores about 1,851.85 minutes of audio.

Reference basis: This result uses the fixed 48khz / 24-bit mono pcm audio PCM profile to turn storage budget back into recording time from 144,000 bytes/s.
Example: For 1 GB, the 48kHz / 24-bit mono PCM Audio PCM estimate gives about 115.74 minutes of recording time.

API, OpenAPI and WebMCP documentation

Explanation

48kHz / 24-bit mono streams 144000 bytes/second (0.144 MB/s). minutes = (GB x 1000) / (0.144 x 60). With input 1 GB, result is 115.740740741 min.

Method & PCM Profile

Method basis: fixed PCM byte-rate estimate inverted to recover recording time from storage size 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 gb to minutes?

GB to minutes 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 GB to min for 48kHz / 24-bit mono?

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