What Does AI Audio Enhancement Do?

AI audio enhancement analyses the spectral content of your recording and applies a targeted signal processing chain — high-pass filtering to remove low-frequency rumble, notch filtering to eliminate 50/60 Hz electrical hum, parametric EQ to boost speech clarity in the 1–4 kHz range, and dynamic compression to normalise loudness levels. All of this runs inside your browser using the Web Audio API with no server upload required.

Unlike desktop tools that require installation or cloud tools that upload your files, EazyStudio's AI Audio Enhancer processes everything locally — ideal for sensitive recordings like interviews, medical consultations, legal calls or unreleased music.

Which Preset Should I Use?

Podcast cleans up voice, reduces room noise and normalises to broadcast-ready loudness — ideal for interviews and podcast publishing. Voice Call applies aggressive noise removal for Zoom, Teams and phone recordings where background noise is heavy. Music uses gentle cleanup that preserves dynamics and warmth, so it won't over-process instruments. Speech boosts the 2.5 kHz presence peak where intelligibility lives — best for lectures, presentations and voice notes. Use Custom when you need precise control over the noise gate, voice boost, de-hum and loudness sliders.

Frequently Asked Questions

Is my audio file uploaded to a server?

No. All enhancement is processed in your browser using the Web Audio API. Your files never leave your device.

Which formats are supported?

MP3, WAV, OGG, M4A and FLAC up to 200 MB. The enhanced file is always exported as WAV to preserve full quality.

Can I record directly in the browser?

Yes. Click the "Record Audio" tab, allow microphone access, and click Start. Your recording is loaded automatically when you stop.

How do I trim before enhancing?

After uploading a file, drag the handles on the Trim bar to set your start and end points. Only that region will be enhanced and exported.

Can I enhance multiple files at once?

Yes — hold Ctrl/⌘ when selecting files in the browser, or drag multiple files onto the drop zone. Each file gets its own download button when processing is complete.
