Minutes to GB for 48kHz / 24-bit 5.1 PCM Audio
60 minutes = about 3.11 GB · fixed PCM recording estimate · 48kHz / 24-bit 5.1 PCM Audio
Direct Answer
At 48kHz / 24-bit 5.1 PCM, 60 minutes of audio needs about 3.11 GB
This result uses the fixed 48khz / 24-bit 5.1 pcm audio PCM profile, anchored to 864,000 bytes/s.
For 15 minutes, the 48kHz / 24-bit 5.1 PCM Audio PCM estimate needs about 0.78 GB.

SwitchExplanation
Formula: GB = (minutes x 60 x 0.864) / 1000 (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.
Duration (minutes): elapsed audio time in minutes.
File size (GB): decimal gigabytes of storage, where 1 GB = 1,000,000,000 bytes.
This route is useful when estimating how much storage a recording will need 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 minutes to gb?
Minutes 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 min 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 (minutes) with the same PCM assumptions.
Can minutes to gb support storage budgeting?
Yes. Minutes to GB is suitable for first-pass recording and archive estimates in PCM workflows.
