SoundBench does not upload, store or see the audio files you open. All processing happens inside your web browser on your own device. Closing the tab removes the files from memory.
Libraries used to process audio (LAME, FFmpeg WebAssembly and jsmediatags) are downloaded from the jsDelivr CDN. They receive normal web requests, as with any website, but not your audio.
Analytics
To understand which tools are used and to fix problems, SoundBench uses Google Analytics and Microsoft Clarity. These services collect information such as pages visited, approximate location, device type and how the page is used, and may use cookies. They do not receive your audio files or their contents.
You can block these services with your browser's tracking protection or a content blocker; every tool keeps working without them.
