How Uncompressed Audio File Size is Calculated
Uncompressed Pulse Code Modulation (PCM) audio in WAV or AIFF containers follows a simple mathematical relationship:
File Size (Bytes) = Sample Rate (Hz) × (Bit Depth / 8) × Channels × Duration (Seconds)
For example, 1 second of 48,000 Hz, 24-bit (3 bytes), stereo (2 channels) audio equals 48,000 × 3 × 2 = 288,000 bytes per second (2.304 Mbps).
