From any recording to an MP3 or a transcript
Phones and apps save sound in many formats: M4A voice memos on iPhone, Opus voice notes in WhatsApp and Telegram, WAV from recorders, FLAC from music downloads, and the sound inside every video. The converters here turn all of them into MP3 that plays on any device, and the cutter trims a song or a recording to the part you want, with fades.
The transcription tools write out what is said in a recording with Whisper, a speech recognition model that understands more than 40 languages. Use them for interviews, lectures, meetings and long voice messages. Everything runs inside your browser, including the speech model, so private recordings are never sent anywhere.
