How the local audio editor works
The browser decodes your selected files into audio samples, draws an approximate waveform, and applies edits to those samples. WAV files are written directly in the page. MP3 files use a self-hosted WebAssembly encoder.
Select and cut
Drag across the waveform, then keep the range or remove it. The Undo button restores the previous project.
Preview the finish
Volume and fades are part of playback, so you can hear the result before creating a file.
Export locally
Prepare WAV immediately or load the local MP3 engine for a smaller file. The result stays on your computer.
Audio editor questions
Does HandyPebble upload my recording?
No. The selected audio is read and processed in the browser tab. Like any website, the page itself is delivered over the internet, but the audio files and edited result are not sent to HandyPebble.
Which input formats work?
The editor accepts audio formats your browser can decode, commonly MP3, WAV, M4A/AAC, and Ogg. Exact support depends on the browser and operating system. Export is consistently available as WAV, with MP3 through the included encoder.
Why does MP3 take longer the first time?
The MP3 option loads a self-hosted 32 MB WebAssembly encoding engine. It is not needed for editing or WAV export, and most browsers cache it after the first use.
Can I edit a long recording?
Browser audio editing uses memory for decoded samples. Version 1.0.0 limits a project to 12 files, 300 MB of source files, and about one hour of decoded audio. Shorter projects are faster and less likely to exceed available memory.
