Send a recording that's too big to send
Training delivered live should teach again as content.
The chain
Get the recording out of Zencastr
Per-guest audio tracks appear in the dashboard after upload completes; download each track (WAV/MP3). Wait for the post-call upload to finish before grabbing tracks — partial files are a classic gotcha.
Compress to speech-optimized Opus
An hour becomes ~20 MB; ten minutes ~3.5 MB — under every attachment cap.
Frequently asked
How do I send a recording that's too big to send?
First compress to speech-optimized opus (whipscribe.com/tools-online/compress-audio). You end up with: The same words, attachable anywhere.
Where does Zencastr store its recordings?
Per-guest audio tracks appear in the dashboard after upload completes; download each track (WAV/MP3). Wait for the post-call upload to finish before grabbing tracks — partial files are a classic gotcha.
Do I need to install anything?
No. The free preparation tools run entirely in your browser (WebAssembly), and transcription is a web upload with an instant no-signup preview.
Is my file uploaded during the preparation steps?
No — the tools-online steps (extract, compress, trim, convert, clean up) process the file locally in your browser. Audio only uploads when you choose to transcribe it.
How accurate is the transcription?
Clear audio in major languages transcribes near-publishable; noisy or accented audio deserves a review pass. The instant preview shows real output on your own recording before you commit anything.
