WAV is an audio container commonly used for uncompressed PCM samples.
MP3 stores compressed audio with broad hardware and software support.
Audio is encoded as MP3 at the selected bitrate.
Source metadata is removed.
Choose trim points, sample rate, channels, volume, and MP3 bitrate when the output uses MP3 compression.
One file is processed per request. The input limit is 100 MB.
The web application validates the file before forwarding it to a private worker. The worker validates the signature again, processes the file inside a unique temporary directory, validates the output, and removes the job directory in a guaranteed cleanup path. Files are not written to the database or retained for analytics.
When you import from a URL, the application fetches only a validated public HTTP or HTTPS address, checks the downloaded file in memory, and applies the same worker cleanup rules. The URL, filename, and file contents are not sent to analytics.
