"Worksheet","Calculate PCM audio storage with channels, sample rate and bit depth","Evidence status","Your configuration"
"Purpose","For uncompressed PCM, multiply sample rate, bit depth, channel count and duration, then divide by eight for bytes. Keep compressed audio estimates separate.","Proposed workflow",""
"Check","Question to record","Decision","Your observation"
"Sample rate","Samples per second per channel","Temporal sampling",""
"Bit depth","Bits per sample","Representation",""
"Channels","Independent sample streams","Multiplies payload",""
"Example","Stereo 48,000 Hz, 24-bit PCM for 60 seconds contains 48,000 × 24 × 2 × 60 ÷ 8 = 17,280,000 bytes of sample data, or 17.28 decimal MB. A mono version has half that payload. These are arithmetic sizes, not an audio-quality comparison.","Illustrative; not a measured product result",""
