Cathode is a browser tool for podcasters, musicians, and anyone who needs to trim or convert a short recording without uploading it to a server. Drop a file in, read it, cut it, and export it, all in this tab.
The waveform and spectrogram show you where the silence, the clipping, and the frequency content actually are, with labeled time and frequency axes you can zoom and pan.
Drag the in and out handles or nudge them with the arrow keys, then preview just the selection on a loop before you commit to it.
Export the trimmed clip to MP3, AAC, or WAV. ffmpeg runs as WebAssembly in the tab, so there is no upload and no server queue to wait on.
The only network request is the one-time download of the audio engine. Your file is never sent anywhere, because there is nowhere on a server for it to go.
