How to extract audio from a Zoom recording
Zoom cloud and local recordings save as MP4 with AAC audio. If you have only the video file and need the audio for transcription, captioning or a podcast edit, VideoSplit extracts it in-browser without sending the recording to a transcription SaaS first.
Zoom already offers an audio-only recording option in the cloud, but if someone sent you the video file and you need the audio, this is a one-click extraction. For transcription workflows, WAV export into Whisper gives the best results.
Step-by-step
- Open VideoSplit.io. Any browser. Privacy-sensitive? This is especially important — Zoom recordings often contain confidential meetings, and VideoSplit never uploads your file.
- Drop the Zoom .mp4 onto the page. Drag and drop. Two-hour meetings typically land around 300–500 MB and process fine.
- Pick WAV for transcription, MP3 for archiving. WAV at 48 kHz is what Whisper and most ASR pipelines prefer. MP3 is fine for an archive-and-listen workflow.
- Download the audio. Saves with the same filename as the Zoom recording.
Tips for better results
- Zoom's Gallery View recording has all speakers in the same audio stream — there is no per-participant track unless the host enabled separate audio files at recording time.
- Long Zoom recordings over 4 GB sometimes split into multiple MP4 files; process each separately and stitch in your DAW or ffmpeg.
- For confidential meetings, VideoSplit's client-side model is a hard requirement — do not pipe sensitive recordings through online converters.
