GB to minutes for 48kHz / 24-bit 5.1 PCM Audio
16 GB = about 308.64 minutes · fixed PCM recording estimate · 48kHz / 24-bit 5.1 PCM Audio
Direct Answer
At 48kHz / 24-bit 5.1 PCM, 16 GB stores about 308.64 minutes of audio
This result uses the fixed 48khz / 24-bit 5.1 pcm audio PCM profile to turn storage budget back into recording time from 864,000 bytes/s.
For 1 GB, the 48kHz / 24-bit 5.1 PCM Audio PCM estimate gives about 19.29 minutes of recording time.

SwitchExplanation
Formula: minutes = (GB x 1000) / (0.864 x 60) (PCM 48kHz / 24-bit 5.1). Why: this page fixes the 48khz / 24-bit 5.1 pcm audio PCM profile so duration-to-size calculations stay tied to one explicit sample-rate, bit-depth, and channel layout.
File size (GB): decimal gigabytes of storage, where 1 GB = 1,000,000,000 bytes.
Duration (minutes): elapsed audio time in minutes.
This route is useful when estimating how much recording time fits into a storage budget under the fixed 48khz / 24-bit 5.1 pcm audio PCM profile.
This conversion is profile-based rather than universal: uncompressed PCM file size depends on sample rate, bit depth, and channel count, so mirror pages should keep the same recording profile to remain comparable.

Frequently Asked Questions
Which PCM settings are fixed for gb to minutes?
GB to minutes 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 GB to min for 48kHz / 24-bit 5.1?
Use the opposite route for 48kHz / 24-bit 5.1 to convert duration (minutes) back to file size (gb) with the same PCM assumptions.
Can gb to minutes support storage budgeting?
Yes. GB to minutes is suitable for first-pass recording and archive estimates in PCM workflows.
