Frequently asked questions
- Does the video leave my computer?
- No. Clapr extracts the audio track entirely in your browser using WebAssembly. The source video is never uploaded anywhere.
- Which formats can I extract from?
- Any video or audio container ffmpeg supports: MP4, MOV, MKV, WebM, AVI, FLV, and many more. The output is MP3 or WAV.
- MP3 vs WAV — which should I pick?
- MP3 192 kbps is the default and ideal for podcasts, sharing, and transcription. MP3 320 kbps is best for music. WAV is uncompressed PCM — pick it if you will do further audio editing or feed it to a speech-to-text model.
- What if my video has multiple audio tracks?
- Clapr currently extracts the first audio track. Multi-track picker is on the roadmap.
- Is there a size limit?
- Up to 4GB per file in-browser. Larger or mobile-device workloads may fall back to server processing (coming soon).
- Does Clapr keep any copy of my audio?
- No. All processing happens in your browser tab. We have no server-side storage for this tool, and nothing is sent to any third party.
- Can I use the output for transcription?
- Yes — that is a great use. Use our Transcribe tool to take it end-to-end, or feed the WAV output to Whisper, Rev, or any ASR tool you prefer.
