Why Notevibes

Why Notevibes Limiter

Brick-wall safety, zero clipping, zero hassle.

Brick-Wall Safe

Threshold −1 dB, ratio 20:1, 1 ms attack, zero knee — peaks never get through. The output is safe for streaming, broadcast, or master delivery.

Catches Every Peak

Anything that would cross the digital ceiling is caught and held just below 0 dB, so a single loud transient can't clip and distort your whole export.

Never Uploaded

Limiting runs in your browser with the Web Audio API. Your file never leaves your device — there is nothing to delete because nothing was sent.

Any Audio Format

MP3, WAV, M4A, FLAC, OGG, and AAC — anything your browser can decode loads instantly, up to 200 MB.

Clean MP3 Output

The limited result previews in the page, then downloads as a 192 kbps MP3 — no watermark, no ads, no attribution required.

Free, Anywhere

No sign-up, no daily limits, no watermark. Works on phones, tablets, and laptops in any modern browser.

Nothing to Upload, Nothing to Leak

The limiting happens on your own device. Your master never touches a server — which is a stronger promise than any “we delete it later”.

One Peak Shouldn’t Ruin the Whole Export

You mixed the whole thing carefully, then one laugh, one door slam, one over-enthusiastic word pushes past the digital ceiling — and the export clips. The old fixes are all a hassle: hunt down the transient by hand, or load a desktop mastering suite for a one-second problem. This limiter does the one thing you need: catch anything above the ceiling and hold it flat, so nothing clips.

A true brick wall, not a maybe

The threshold sits at −1 dB with a 20:1 ratio, a 1 ms attack, and zero knee — the classic brick-wall configuration. Below the threshold your audio passes untouched; above it, nothing gets through. That guarantee is exactly what streaming platforms, broadcast specs, and master delivery ask for.

Safety, not loudness — and how they fit together

A limiter is a specialist: it does almost nothing until a peak threatens the ceiling, then stops it dead. When you want to smooth out dynamics across the whole track, that’s the audio compressor. When a file is simply too quiet, the volume booster raises it — and running the limiter afterward keeps that boost from clipping.

Private because it never leaves

Unreleased masters and client work are exactly the files you don’t want on someone else’s server. Here the limiting runs on your own device — the same Web Audio engine that powers the full Notevibes editor. Because there’s no server doing the work, there’s nothing to meter: no watermark, no daily cap, no sign-up, files up to 200 MB.

The last step before you publish

Limiting is usually the final safety pass. If you also need to hit a platform’s loudness number, the loudness normalizer matches −23, −16, or −14 LUFS, and when the track needs cuts, cleanup, or stacked mastering, open it in the online audio editor.

Need Full Mastering?

The full Notevibes editor stacks limiter with EQ, compressor, normalizer, and effects — process whole tracks in one pass, then export to MP3 or WAV.

FAQ

Audio Limiter FAQ

What is an audio limiter?

A limiter is a special compressor with a very high ratio that catches peaks above a fixed threshold. Anything above the threshold is held flat — no matter how loud the source, the output never exceeds the ceiling. Limiters are used to prevent clipping during recording, mastering, broadcast, and streaming.

How does this limiter work?

It uses the Web Audio DynamicsCompressor with threshold −1 dB, ratio 20:1, attack 1 ms, release 50 ms, and zero knee — a brick-wall configuration. Anything that would clip the digital ceiling is caught and held just below 0 dB.

When should I use a limiter?

Use a limiter on any audio you plan to upload to streaming, broadcast, or hand off as a master — including podcasts, audiobooks, music exports, voiceovers, and YouTube audio. It guarantees zero clipping.

Will it make my audio louder?

Slightly — only the peaks are pulled down, so the average level can come up without clipping. But this limiter is configured for safety, not loudness. If you need to make audio noticeably louder, run the volume booster first and finish with this limiter.

Limiter vs. compressor — what's the difference?

A compressor reduces dynamic range smoothly across a range of levels. A limiter is an extreme compressor — it does almost nothing below the threshold but completely stops anything from going above it. Use compression for tone-shaping, limiting for peak safety.

Is the audio limiter free?

Yes. Completely free with no sign-up, no watermark, and no limits. Max file size is 200 MB.

Is my audio file uploaded to a server?

No. The limiter runs entirely in your browser using the Web Audio API. Your file never leaves your device.

What audio formats are supported?

MP3, WAV, M4A, FLAC, OGG, and AAC. Anything your browser can decode will load. Output is exported as a 192 kbps MP3.
