Understanding Audio Bit Depth

Bit depth determines the dynamic range and noise floor of digital audio. Higher bit depths provide more headroom and lower noise.

Common Use Cases

8-bit: Retro gaming, chip music, size-constrained applications
16-bit: CD audio, general-purpose audio, streaming
24-bit: Professional recording, mixing, mastering
32-bit float: Digital audio workstations, maximum dynamic range

Bit Depth	Dynamic Range	Theoretical SNR
8-bit	48 dB	49.93 dB
16-bit	96 dB	98.09 dB
24-bit	144 dB	146.24 dB
32-bit float	1528 dB	Infinite (theoretical)

Frequently Asked Questions

Which browsers support this tool?

Modern browsers with Web Audio API support. Chrome, Firefox, Safari, and Edge all work well. Codec support varies by browser.

What's the maximum file size I can process?

Depends on your device's memory. Typically 50-100MB for most computers. Very long files may cause browser slowdowns.

When should I use WAV vs WebM Opus?

Use WAV for maximum quality and professional work. Use WebM Opus for web delivery where smaller file sizes are important.

How It Works

Audio is decoded using your browser's AudioContext
Processing happens in an OfflineAudioContext for bit depth conversion
WAV files are encoded manually using RIFF/WAV format
WebM Opus uses MediaRecorder API if supported

For informational and educational purposes only. Processing occurs locally in your browser and depends on your device codecs. Audio quality and compatibility may vary. For professional work verify loudness levels, formats, and legal rights before publishing.
