About AinoiseRemover

AinoiseRemover is a free, browser-based audio toolkit built for anyone who needs to clean up recordings quickly and privately. Our flagship tool uses RNNoise — an open-source recurrent neural network — to remove background noise from voice recordings in real time.

We believe audio tools should be accessible without subscriptions, account walls, or file upload requirements. Every tool on AinoiseRemover processes your audio locally in your browser. Your files are never sent to our servers.

What we offer

• AI noise removal powered by RNNoise (WebAssembly)
• Audio editing: trim, merge, split, reverse, fade
• Format conversion: stereo/mono, sample rate, WAV export
• Audio quality tools: normalize, compress, equalize
• Browser-based voice recorder with live VU metering
• Speech-to-text transcription via native Web Speech API

Technology

Built with Astro and deployed on Cloudflare Pages. Audio processing uses the Web Audio API and open-source WebAssembly libraries. No paid APIs or cloud processing for core features.

Limitations

Browser-based audio processing has practical constraints. Very large files may consume significant memory. AI model accuracy varies by recording conditions. We do not promise specific noise reduction quality — listen to your results and use the controls accordingly.
