A waveform shows loudness over time. A spectrogram shows time and frequency, which makes some problems much easier to find. A click, whine, hum stripe, chair scrape, or bump can appear as a shape you can select instead of guessing from the waveform alone.
The AudioMultiCut spectrogram editor is made for targeted repairs. It is not meant to sterilize an entire recording or replace a restoration suite.

Listen. Hear that? Every recording has one sound that ruins it. So let's see it. There. A click. Brush it. Gone. A waveform shows loudness over time. It can't show you the problem. A spectrogram adds frequency, so the problem gets a shape you can point to. This is the AudioMultiCut spectrogram editor. It's built for targeted repairs, not for sterilizing a whole file. Set the brush: minus 18 dB by default. Short noises are the best case. Draw a box around the click. Pull it down. Just that spot. Preview the result before you export. Clean. The speech around it stays intact. A hum or a whine shows up as a thin horizontal line. Select only that frequency band, and reduce it carefully. The voice stays. Small selections matter. Brush a big block, and the repair sounds dull. Keep it small. Keep it clean. But if the whole recording is noisy, clipped, or distorted, a brush isn't enough. Use a full restoration tool. For the spots you can see, everything runs in your browser. Nothing is uploaded. AudioMultiCut. Brush a visible noise. Free, at audiomulticut.com
Short noises with a visible shape
The best use case is a short problem that stands out visually: a click, a mic bump, a squeak, a cough edge, a plosive thump, or a narrow electrical tone. Select the smallest area that covers the problem and preview the result.
Small selections matter. If you brush a large block, you may remove useful tone along with the noise, and the repair can sound dull or strange.
Hum and narrow bands
A steady hum or whine often appears as a horizontal line. A spectrogram view can make that obvious in a way a waveform cannot. Select only the frequency area that contains the problem, then reduce it carefully.
This is where the tool feels different from a normal cutter. You are reducing part of the sound inside a specific time range, which can preserve the surrounding speech or music better.
When to use something stronger
If the entire recording is noisy, clipped, distorted, or badly recorded, a brush is not enough. Use a dedicated restoration tool or a full editor with noise profiles, de-click, de-hum, spectral repair, and careful monitoring.
The spectrogram editor is best for the obvious trouble spots you can point to. It is not a one-button rescue for a broken recording.
