Practical Examples

Podcast Production

Record a video podcast, extract 48kHz WAV audio, normalize levels to -16 LUFS, and trim silence from the beginning and end for professional podcast distribution.

Music Sampling

Extract audio from vintage concert footage at 96kHz/24-bit, preserving the highest quality for music production and sampling in DAW software.

Archival Preservation

Convert old family video recordings to 44.1kHz WAV files for long-term archival, ensuring audio preservation separate from deteriorating video formats.

Audio Quality Reference

Use Case	Sample Rate	Bit Depth	Loudness Target
Music Production	48-96 kHz	24-bit	-14 to -16 LUFS
Podcast/Voice	44.1-48 kHz	16-24 bit	-16 to -18 LUFS
Archival	44.1-96 kHz	24-32 bit	Preserve Original

Frequently Asked Questions

What video formats are supported?

This tool supports any format your browser can decode, including MP4, MOV, AVI, WebM, and MKV. Support varies by browser and operating system.

Is there a file size limit?

Processing happens entirely in memory, so very large files may exceed available RAM. For best results, keep files under 500MB. The tool will warn you if a file is too large.

When should I use WAV vs WebM Opus?

Use WAV for professional editing, archiving, or when you need lossless quality. Use WebM Opus for web distribution, streaming, or when file size is important - it offers excellent quality at much smaller sizes.

Does normalization cause clipping?

Our normalization uses true peak detection and applies soft clipping when necessary to prevent digital distortion while maximizing loudness.

How It Works

Video file is decoded using browser's native MediaElement and Web Audio API

Audio is processed with OfflineAudioContext for sample rate conversion, channel mixing, and normalization

WAV files are encoded by manually writing RIFF headers and PCM data to ArrayBuffer

WebM Opus uses MediaRecorder API when supported by the browser

All processing uses high-quality resampling and dithering when reducing bit depth
