Why Notevibes Voice Enhancer
A studio voice chain, calibrated and one click away.
One Click, Six Stages
De-rumble, EQ, compress, de-ess, limit, normalize — the full podcast post chain fires in order from a single button, nothing to configure.
Broadcast-Safe Levels
A brick-wall limiter at -1 dB and a final normalize to -0.4 dB mean the result never clips and lands where streaming and audiobook platforms expect.
Voice-Tuned Presets
Each stage uses the settings a voice engineer reaches for: a high-pass at 80 Hz, a 3 kHz presence lift, gentle 3:1 compression, and sibilance tamed at 6 kHz.
Preview Before You Save
Hear the enhanced version right in the page and pick your MP3 bitrate before anything downloads — no blind processing.

The whole chain runs in your browser with the Web Audio API. Your recording never leaves your device — there is nothing to delete because nothing was sent.

Podcast-Ready Voice in One Click
A raw voice recording almost never sounds finished. It’s thin where it should be present, boomy where a mic picked up the desk, and loud one second and buried the next. Fixing it by hand means stacking a high-pass, an EQ, a compressor, a de-esser, and a limiter — and knowing the right numbers for each. This tool makes those six moves for you, in the right order, from a single button.
The whole chain, in the right order
Order matters: de-rumble first so the compressor isn’t reacting to low-end thud, EQ for presence, compression to even out the swings, a de-esser to keep the highs from getting harsh, then a limiter and a final normalize so nothing clips and every file lands at the same level. It’s the same six-stage sequence engineers run on spoken voice — here it’s calibrated to voice-tuned defaults and applied in one pass.
Hear it before you keep it
The enhanced version plays right in the page, so you can judge it before anything downloads, and you pick the MP3 bitrate on the way out. Because the processing runs on your own device, there’s no upload bar, no queue, and no server copy — which also means there’s nothing to charge for. Files up to 200 MB, no watermark, no sign-up.
Polish, not noise removal
This chain evens and brightens a voice, but it doesn’t subtract steady hiss or hum. When there’s background noise, clean it first: the browser-side noise remover auto-subtracts a noise profile, and for badly degraded recordings the AI noise reducer and background noise remover do a heavier, model-based pass — run one, then enhance. For control over every knob, open the file in the online audio editor.
Want Manual Control Over Each Stage?
The full Notevibes editor lets you tune every effect in the chain by hand, audition each stage, and layer AI cleanup — then export to MP3 or WAV.

Voice Enhancer FAQ
What does the voice enhancer do?
It runs a fixed six-stage cleanup chain on your recording — de-rumble, voice EQ, compressor, de-esser, limiter, and normalize — in the order a voice engineer would apply them. One click does the whole thing; there is nothing to configure.
What does each stage do?
A high-pass at 80 Hz removes rumble, a +3 dB lift at 3 kHz adds presence, a 3:1 compressor evens out volume swings, a de-esser tames harsh S sounds at 6 kHz, a brick-wall limiter catches peaks at -1 dB, and a final normalize sets a consistent -0.4 dB peak.
Will it remove background noise?
Not really — this is a polish chain, not a denoiser. It tames some low rumble, but for steady hiss, hum, or fan noise run the file through the noise remover first, then enhance. For badly degraded recordings the AI noise reducer does a heavier, server-side cleanup.
Is it safe for streaming and audiobooks?
Yes. The limiter holds peaks at -1 dB and the final normalize lands at -0.4 dB, comfortably inside the peak limits podcast platforms, YouTube, and audiobook distributors expect.
Will it work on music?
The chain is tuned for spoken voice — the presence lift and de-esser target the voice band — so on a full music mix it can sound unnatural. For music, use the individual EQ, compressor, and limiter in the full editor with your own settings.
Is my recording uploaded to a server?
No. The whole chain runs in your browser with the Web Audio API. Your file never leaves your device — there is nothing to delete because nothing was sent.
Is the voice enhancer free?
Yes — completely. Because it runs on your device rather than our servers, there is nothing to meter: no watermark, no sign-up, no limits. Files up to 200 MB.
What formats can I use?
MP3, WAV, M4A, FLAC, OGG, and AAC up to 200 MB. The enhanced result downloads as an MP3 at the bitrate you pick, 192 kbps by default.
