Privacy-focused audio tool
Audio producers often have to deal with recordings made in different formats, and at different sample rates and bit depth. Sometimes it is not clear what is in a file, and whether the levels are within an acceptable range. There are many different tools available that can help, but these usually need to be installed on the local machine. Many people turn to free online tools out of convenience and availability. However, these require you to upload your media to an unfamiliar server, which come with legal, security, and privacy risks.
Aud-it offers the convenience of a web tool with the privacy of local software by doing all of the processing in the browser itself. We created it by compiling FFmpeg and MediaInfo into WebAssembly so that they can be run from within a webpage. We then used Material UI to create a simple but powerful interface with support for batch processing. Aud-it can analyse the contents of any media file, decode any audio format, and calculate the loudness and true peak values. It can then normalise to a target loudness value, and export to WAV or FLAC using any sample rate or bit depth.
We are currently in the process of making the tool available as open-source software. Sign up to our newsletter to get notified when it becomes available.
