Batch Audio Processing Without Zipping

This tool solves the common problem of needing to process multiple audio files individually rather than bundling them in a zip archive. Perfect for content creators, podcast editors, and audio engineers who need to maintain file organization and quick access.

Step-by-Step Guide

Drag and drop multiple audio files or use the file browser
Configure output settings (format, sample rate, bit depth, channels)
Files process sequentially in the background
Download each processed file individually as it completes

Real-World Examples

Scenario	Input Files	Settings	Output
Podcast episodes	5 MP3 interviews	WAV, 48kHz, 16-bit, Stereo	5 individual WAV files

Frequently Asked Questions

Which audio formats are supported?

Input: Any format your browser can decode (typically WAV, MP3, M4A/AAC, OGG, FLAC). Output: WAV (always) and WebM Opus (if browser supports MediaRecorder).

Are there file size limits?

Processing happens in memory, so very large files may cause browser slowdown. For best results, keep individual files under 100MB.

Why no ZIP download?

Individual downloads allow you to organize files as they complete and avoid waiting for a large ZIP to generate and download.

How It Works

Files are decoded using Web Audio API (AudioContext.decodeAudioData)
Processing happens via OfflineAudioContext for sample rate conversion and channel mixing
WAV encoding uses manual RIFF/PCM header writing to ArrayBuffer
WebM Opus encoding uses MediaRecorder API when available
Files download individually via URL.createObjectURL

Bit depth reduction uses truncation without dithering. Resampling uses browser's default method. Loudness normalization uses peak-based approach.

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