Does my audio file get uploaded to a server?

No. Every step — noise analysis, filtering, enhancement and export — happens entirely inside your browser using the Web Audio API. Your audio files never leave your device.

Which audio formats are supported?

You can upload MP3, WAV, OGG, M4A and FLAC files up to 200 MB. The enhanced audio is exported as WAV which retains all the improvements at full fidelity.

Can I record directly without uploading a file?

Yes. Click the "Record Audio" tab, grant microphone permission, and record directly in your browser. The recording is immediately loaded for enhancement.

How does the Trim feature work?

After uploading, drag the start and end handles on the waveform to select the region you want to keep. Only that portion will be enhanced and exported — great for cutting out silence or isolating a specific segment.

How does AI noise removal work in a browser?

The tool analyses your audio's frequency spectrum and applies a combination of adaptive high-pass filtering (to remove low-frequency rumble), notch filtering (to cut electrical hum), parametric EQ and dynamics compression to suppress background noise without affecting voice frequencies.

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?

Noise Removal is best for recordings with consistent background noise — air conditioning, fan hum, road traffic, or a noisy room. Voice Clarity is designed for podcasts, interviews and video calls — it boosts the 2.5 kHz presence peak where speech intelligibility lives. Full Enhancement combines both and also normalises loudness, ideal for YouTube or podcast publishing. Use Custom when you need precise control, for example when enhancing music that shouldn't have the voice-clarity EQ applied.
