You can edit audio for free Audio Editor — Version 3.0.1 Update Audio Editor is a free, browser-based tool for slicing, shaping, and exporting audio. Open a sound file, let the app detect its transients, fine-tune the slice points, preview your edits with tempo, pitch, envelope, compression, and three-band EQ controls, and export the result as a ready-to-use pack of WAV files together with an SFZ sampler map and a MIDI file. Everything runs on your own computer, and your audio never leaves your device. This release is a focused quality update. We went through the application from start to finish, fixed the problems that got in the way of real work, smoothed out the controls, and hardened the parts of the app that had been prone to failing quietly. Below is a complete summary of what changed. Reliability fixes you will notice immediately Opening a file now works every time. Previously, loading a track could fail part-way through: the file name would not appear, the on-screen controls could keep the previous file's settings, and the export could end up with the wrong name. That whole chain has been repaired, so every time you open a file its name is shown correctly, all controls reset to sensible defaults, and exports are named after the file you are actually working on. The waveform always draws, even for long recordings. On lengthy files, or when you zoomed in very far, the waveform could go completely blank while the markers kept moving over an empty strip. The display now stays visible and correctly aligned at every zoom level and for long recordings, so you can always see what you are editing. Exporting no longer gets stuck. If your selection contained a very short slice, the export could fail silently and leave the Save dialog frozen. Exporting is now robust: short slices are handled gracefully, and the Save button always recovers instead of hanging. Smoother, more predictable controls The transient-detection slider now tells the truth. Its position and its on-screen value match the sensitivity that is actually applied, both when the app starts and after you open a new file. Zooming is smooth from end to end. The old zoom had a dead zone that made the first click jump too far. Zoom now steps evenly in and out across the full range, so you can settle on exactly the level of detail you want. Keyboard shortcuts respect what you are doing. Space to play or pause, and Delete to remove a marker, now stay out of your way while you are typing in a text field, such as the bars-and-beats entry in the Save dialog. They still work everywhere else. File names are handled safely. The name of the file you open is now always shown as plain text, and multi-part names such as "my.mix.take1.wav" keep their full base name when exported, instead of being cut off at the first dot. Stability and housekeeping under the hood Beyond the visible fixes, we resolved a number of issues that made long editing sessions less stable. A memory leak that caused zooming to slow down over time has been eliminated. The export and MIDI-writing pipeline is now protected against edge cases that could previously cause it to hang or crash, including unusual tempo values. Internal playback and rendering paths have been tightened so that starting, looping, and stopping playback behave consistently. We also cleaned up the extension package itself, removing outdated configuration entries that no longer apply to modern browsers. Tested from end to end This update was verified with an automated test suite that loads the extension into a real browser and exercises the full workflow: opening files, drawing the waveform, detecting and adjusting slices, playing back, and exporting a complete ZIP archive. Every test passes, which gives us confidence that the fixes hold together in actual use rather than only in theory. Everything you rely on, still here All of the app's capabilities remain in place: automatic transient detection with an adjustable threshold, manual nudging and placement of slice markers, tempo and pitch preview, an amplitude envelope with attack, hold, and decay, a compressor, a three-band equalizer, adjustable time-signature and MIDI-mapping options with several musical scales, and one-click export to a ZIP that contains your sliced WAV files, an SFZ instrument definition, and a MIDI file. Privacy and offline use Audio Editor does its work entirely in your browser. Your files are processed locally and are never uploaded to any server, so you can use it with confidence and even without an internet connection. We hope this update makes Audio Editor faster to trust and more pleasant to use. Thank you for using the app; your feedback and ratings help us keep improving it.
