🎵 Audio Converter
Load an audio file, choose sample rate and channels, and export a WAV in one click. Great for normalising recordings. Runs locally: no upload.
Note: the pure-front-end version exports WAV (lossless). MP3 encoding needs a server or extra library.
❓ Frequently asked questions
Can it output MP3?
The current front-end version exports WAV (lossless). MP3 encoding needs an extra library or server; this tool stays zero-upload and instant, so it outputs WAV only.
Why change sample rate / channels?
Speech recognition and phone audio often use 8k/16k mono; music uses 44.1k stereo. Matching the format helps downstream tools.
Is my file leaked?
No, everything is processed in the browser.
📚 How to use
Different tasks need different audio specs. Load the file, set parameters, export a standard WAV.
Steps
