Audio Specifications
Audio quality depends on sample rate, bit depth, and channels.
Common sample rates:
- 8,000 Hz: Telephone quality
- 22,050 Hz: AM radio quality
- 44,100 Hz: CD quality (standard)
- 48,000 Hz: DVD/Blu-ray, professional video
- 88,200 Hz: High-resolution audio (2x CD)
- 96,000 Hz: Studio/professional audio
- 192,000 Hz: Ultra high-resolution audio
Common bit depths:
- 8-bit: Low quality (256 levels)
- 16-bit: CD quality (65,536 levels)
- 24-bit: Professional studio (16.7 million levels)
- 32-bit float: Mastering, high headroom
Bit rate formula:
- Bit rate (bps) = Sample Rate x Bit Depth x Channels
- CD quality: 44,100 x 16 x 2 = 1,411,200 bps = 1,411 kbps
File size formula:
- Size (MB) = Bit Rate x Duration (seconds) / 8 / 1,048,576
- 1 minute of CD audio = about 10.1 MB (uncompressed WAV)
