The Vocal Checker lets you drop in a recording and see clipping, noise, rumble and level problems, with plain-English fixes. Use it on a finished take before publishing, read each result, fix the most important problem first and check again. It runs in your browser and the tool describes itself as private.
Before a vocal recording goes public, it is worth checking the basics that listeners notice most: whether the peaks are clipping, whether there is noise or rumble in the quiet parts, and whether the level is steady. Those problems are easy to miss after many hours of listening, and a fresh check can catch them quickly. The Vocal Checker is designed for this job. You drop in a recording, and it reports the problems it finds with plain-English fixes.
This guide walks through a check from start to finish: what to prepare, how to run the check, how to read the results and how to act on them. It is written for podcasters, singers and voice-over artists who want a quick, honest review before publishing.
The Vocal Checker looks for four kinds of problem: clipping, where the loudest sounds are cut off; noise, where a steady background sits under the voice; rumble, where low-frequency sound builds up; and level, where the voice is too quiet or too loud overall. Each one affects how the recording sounds, and each has a different fix. A recording can have one, several or none of them.
The tool does not judge the performance. A recording can be technically clean and still need a better take. Use the check for the technical side, and your ears for the rest.
Export the recording in the form you plan to publish, or as close to it as possible. Check the file plays from start to end in a media player, so you know it is complete. If the recording has several sections, you can check the whole file, or check the sections that worry you most. A finished file gives the most useful results, since an early rough edit may show problems you will fix anyway.
Drop the file into the Vocal Checker in your browser. The tool analyses the recording and reports its findings. Take a moment to read each result before changing anything, since one problem can cause another in the report. Note the results you want to act on, and the order in which you will fix them.
Start with clipping, because it cannot be fully repaired and it affects everything else. If the recording clips, re-record or re-export with lower levels before dealing with other problems. Next, look at noise and rumble, which are easier to reduce but can be damaged by heavy processing. Finally, check the level, since changing it can bring noise up or push peaks into clipping.
After each fix, listen to the recording on headphones and on a phone speaker. A correction that reduces a problem on the report but makes the voice sound thin or distant is not an improvement. Compare the revised version with the original at the same level, and keep the one that sounds better to a listener.
A check on one file can reveal a pattern across several files, such as clipping at the start of each take, or a noise floor that rises late in a session. Use those patterns to change the setup for the next recording, rather than fixing the same problem at the editing stage every time.
Compare the level and the noise of the file with the others in the same project. A take that sits clearly louder or quieter than the rest will stand out in the final mix, even when it passes the basic checks. Use the same clip length and position in the check, so the comparison is fair.
A check is only as good as the file it reads, and the tool cannot judge taste, timing or performance. Results describe what is measurable, and your ears decide what matters. If a recording has serious problems, the best fix is usually a new take, placed closer to the microphone in a quieter room.
Run a check on your next finished vocal before you publish. The Vocal Checker is free and runs in your browser. If you record on a phone, the Tunedzy Go page explains how to clean a phone recording in your phone’s browser, and the guide to true peak explains the clipping check in more depth.
