Audio tools that run in your browser
YourDevice audio tools do the heavy lifting right inside your browser — no installs, no sign-ups and no queue. Transcribe audio online free with in-browser speech recognition that turns podcasts, interviews, voice memos and video into editable text and subtitles. Clean up recordings with the background-noise remover, or generate natural narration with on-device text to speech. Because every step is on-device audio processing, your files are never uploaded — nothing is streamed to a server, and there are no length limits or per-minute fees. It is the private, unlimited way to work with sound: open a file, let your own hardware do the work, and download the result. These browser audio tools stay free to use as often as you like.
