Podcasters use this set for the editing and prep work around an episode: record a quick voice memo or intro with Voice Recorder, convert an exported MP3 to WAV for editing software that expects uncompressed audio, and slow down a guest recording with Slow Down Audio to catch a mumbled line while transcribing.
Recordings stay on your device the whole time — audio is decoded, converted or slowed in the browser tab itself, not streamed to a remote service, so a guest interview or unreleased episode is never sitting on someone else's server. No sign-up, no upload limit, no watermark on the audio.
