How the audio enhancer works

Upload your audio

Drop any audio or video file into the audio enhancer — MP3, WAV, M4A, FLAC, OGG, or a clip from your camera roll. Files up to 500 MB stay on your device; nothing is sent to a server for processing.

Choose enhancement

Pick denoise, normalize, EQ, or bass boost and adjust the sliders until the waveform sounds right. You can chain passes — enhance, download, then re-upload for a second round of cleanup.

Download enhanced audio

Export your enhanced track as MP3, WAV, or OGG. Use the result on YouTube, Spotify, podcast hosts, or drop it into your DAW for further mixing.

What this audio enhancer includes

This free audio enhancer runs entirely in your browser — denoise rumble, normalize loudness, shape tone with EQ, and boost bass before you publish. No upload, no waiting in a cloud queue.

Light denoise

The audio enhancer applies a high-pass filter to cut low-end rumble plus a gentle noise gate for steady background hiss — ideal for voiceovers, Zoom recordings, and podcast intros recorded in imperfect rooms.

Loudness normalize

Make quiet clips louder and consistent so they sit at a competitive level on YouTube, TikTok, or podcast platforms — without clipping or harsh distortion.

3-band EQ & bass

Shape tone with independent low, mid, and high shelves, then add a dedicated bass boost when vocals or instruments need more warmth and body.

Private, local processing

Unlike cloud-based audio enhancer services, every filter runs in your browser tab. Your recordings, interviews, and demos never leave your device.

Audio enhancer FAQ

Is this a professional mastering audio enhancer?+

No — it is a fast browser audio enhancer for basic cleanup before you publish. For heavy noise, room echo, or stem separation, use a dedicated DAW plugin or an AI denoiser.

Will denoise remove music from my track?+

The audio enhancer applies light filtering and gating, not AI stem separation. It works best on speech with steady background noise — fan hum, AC hiss, or low rumble — rather than full music beds.

Is my file uploaded to your servers?+

No. This audio enhancer decodes, filters, and encodes entirely on your device using Web Audio APIs. We never receive your audio.

Can I chain multiple enhancements?+

Yes. Run one pass — say denoise plus normalize — download the result, then upload it again for EQ or bass boost. Many creators use the audio enhancer twice for voice recordings that need extra cleanup.
