Audio File SizeGigabytes to Hours At 48khz 32bit Stereo

GB to hours for 48kHz / 32-bit stereo PCM Audio

Methodology·How We Verify

Snapshot

At 48kHz / 32-bit stereo PCM, 16 GB stores about 11.57 hours of audio.

Reference basis: This result uses the fixed 48khz / 32-bit stereo pcm audio PCM profile to turn storage budget back into recording time from 384,000 bytes/s.
Example: For 1 GB, the 48kHz / 32-bit stereo PCM Audio PCM estimate gives about 0.72 hours of recording time.

API, OpenAPI and WebMCP documentation

Explanation

48kHz / 32-bit stereo streams 384000 bytes/second (0.384 MB/s). hours = (GB x 1000) / (0.384 x 3600). With input 1 GB, result is 0.72337962963 h.

Method & PCM Profile

Method basis: fixed PCM byte-rate estimate inverted to recover recording time from storage size at 0.384 MB/s.
Profile reference: 48kHz / 32-bit stereo PCM Audio (384,000 bytes/s; 0.384 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 hours?

GB to hours uses 48000 Hz, 32-bit depth, and 2 channels for this profile.

How is the 23.04 MB per minute factor calculated for 48kHz / 32-bit stereo?

Bytes per second = 48000 × (32 / 8) × 2 = 384000 bytes/s. Using decimal MB (1 MB = 1,000,000 bytes), that is 0.384 MB/s or 23.04 MB/min.

How do I reverse GB to h for 48kHz / 32-bit stereo?

Use the opposite route for 48kHz / 32-bit stereo to convert duration (hours) back to file size (gb) with the same PCM assumptions.
