Audio Convert Overview
Audio Convert is a browser-based speech to text workspace that turns recordings into reviewable transcripts. Audio Convert accepts an uploaded MP3, WAV, M4A or MP4 file, a live browser recording, or a supported media URL, then returns an AI transcription produced with OpenAI Whisper across 100+ languages. Speaker labels and timestamps stay attached, so an interview or meeting can be checked against the source audio. The in-browser editor lets you search the transcript, correct proper nouns and rename speakers before exporting TXT, SRT, VTT, JSON, PDF or DOCX. Five free transcription minutes are available to start; paid plans add AI Summary, transcript chat and translation.
