[Open Spectrogram Editor](https://audiomulticut.com/tools/spectrogram-editor)[See How It Works](https://audiomulticut.com/how-it-works) Select time and frequency Brush targeted noise Preview edited result ![Spectrogram Editor and Noise Brush showing selected noise areas on a frequency view.](https://audiomulticut.com/_next/image?url=%2Farticle-screenshots%2Ftools-spectrogram-editor.jpg&w=1600&q=75&dpl=dpl_2JMPia5CMxdedvqoVqs9b5z7XM4q) 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](https://audiomulticut.com/tools/spectrogram-editor) is made for targeted repairs. It is not meant to sterilize an entire recording or replace a restoration suite. ![Selected noise regions in the AudioMultiCut spectrogram editor.](https://audiomulticut.com/_next/image?url=%2Farticle-screenshots%2Ftools-spectrogram-editor.jpg&w=1600&q=75&dpl=dpl_2JMPia5CMxdedvqoVqs9b5z7XM4q) ## 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 not deleting time; you are reducing part of the sound inside that time, wich 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](https://audiomulticut.com/tools/spectrogram-editor) is best for the obvious trouble spots you can point to. It is not a one-button rescue for a broken recording. ## More noise cleanup guides [Targeted browser repair versus professional restoration ### Best Spectrogram Editor Alternatives for Noise Repair Compare AudioMultiCut's spectrogram editor with iZotope RX, Audacity spectrogram workflows, Adobe Audition, DAWs, and simple noise reducers.](https://audiomulticut.com/articles/best-spectrogram-editor-alternatives)[Make quiet or uneven clips easier to hear ### Best Use Cases for an Online Audio Volume Normalizer When to normalize audio, raise quiet recordings, add light compression, and export a more consistent file without turning the process into mastering.](https://audiomulticut.com/articles/audio-volume-normalizer-use-cases)[Use the right tool at the right stage ### How to Combine AudioMultiCut Tools Without Making the Edit Messy A practical workflow for using the cutter, remove-parts editors, normalizer, audiogram maker, video tools, and spectrogram editor together without losing track of the job.](https://audiomulticut.com/articles/combine-audio-tools-workflow) ## Related pages and tools [Spectrogram Editor→](https://audiomulticut.com/tools/spectrogram-editor)[Audio Volume Normalizer→](https://audiomulticut.com/tools/audio-volume-normalizer)[Combine AudioMultiCut Tools→](https://audiomulticut.com/articles/combine-audio-tools-workflow) ## Brush a visible noise Open a file, find the sound on the spectrogram, select the area, and preview the cleaned result before exporting.
