About This Tool

The tool provides in-browser editing and processing of audio files without requiring software installation. It supports trimming, loudness normalization, noise reduction, EQ presets, and format conversion, with batch processing for multiple files. Conceptually, edits are applied through a non-destructive processing chain that outputs new audio while preserving original metadata when available. The platform targets podcasters, voiceover artists, and musicians who need reliable, repeatable results across episodes or tracks. It differentiates itself by offering browser-only access, transparent processing parameters, and batch workflow capabilities that reduce turnaround time. Core features include per-file statistics, loss-aware resampling, and metadata preservation to maintain track information across exports. Use cases include episode post-production, on-the-go voice edits, and quick demos for clients. The tool emphasizes reproducibility—by applying the same target loudness and processing steps across projects, users achieve consistent loudness and tone. The absence of required local software lowers friction for solo creators and small teams seeking a scalable, lightweight solution for routine audio cleanup, mastering, and format delivery.

How to Use

  1. Provide inputs: Upload one or more audio files and set optional start_time, end_time, target LUFS, and noise reduction.

Frequently Asked Questions

Find Quick Answers

What audio formats are supported for input and output?
Input supports MP3, WAV, OGG, and FLAC; output can be MP3 or WAV, with additional formats available based on the selected processing chain. Lossy formats may incur minor quality changes during encoding.
Can I process multiple files at once?
Yes. The tool supports a batch queue where each file is processed with the same processing chain or individually customized settings. Results are exported as a grouped set of files with consistent metrics.
What are the limits for processing in the browser?
Processing limits depend on device memory and CPU. Very long files or large batch queues may trigger longer runtimes or queued processing. Large uploads are managed in the browser with chunked handling to minimize crashes.
