Nova Audio Converter is a free, browser-based collection of audio processing tools. It supports format conversion (to WAV), trimming, volume adjustment (0–500%), fade-in and fade-out, speed change, and mono conversion.

How to use it

Pick a tool, then drag and drop an audio file or click to select one. For trim, enter the start and end times in seconds. For volume, enter a percentage. For fade, enter the fade-in and fade-out duration. For speed, enter the multiplier — note that pitch also changes with speed. Mono conversion requires no extra input. When you're ready, click Download to save the processed audio as a WAV file.
