Perkforge
How it works
Load audio, enter start and end times, adjust gain and fades, preview the result and download WAV. Nothing is uploaded and no account is required.
Useful to know
Input formats depend on your browser. Export is uncompressed 16-bit PCM WAV, not MP3. Limits: 25 MB input and 10 minutes of decoded audio. No microphone permission is requested.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
