Free Online Audio File Cleaner
Quick & easy cleaner for your audio files




Maztr's free online Audio File Cleaner is a quick and easy tool you can use right in your browser, without downloading any software, to make your audio files sound better. No account or login is required to use it.

Our Audio File Cleaner can sharpen your audio files by reducing their signal-to-noise ratio. You can use it to maximize the volume and increase quieter sections of your audio files to give a richer, fuller sound. It also gives you the option to convert between stereo and mono, increase the tempo (not the pitch) by up to 50% and convert the bitrate up or down between 64kbps and 192/320kbps. Maztr Pro users can also download the output in wav format, and have a 300MB maximum file size.

The Cleaner is designed for users who don't want to sign up for an account and want an audio tool they can use quickly, on the fly. It works particularly well with podcasts, which are often too slow, use unecessary stereo, and vary considerably in volume as well as dynamic range.

Please note that this Audio File Cleaner is not designed to replace our Mastering process. If you want the best results, we recommend you register for one of our accounts which have a much wider range of advanced "state of the art" Mastering tools to make your songs and podcasts really shine.
