Send a recording that's too big to send
The chain
Get the recording out of Riverside
After a session, download per-participant WAV/MP4 tracks from the recording page — that's the platform's whole point. Use the separate per-speaker tracks: diarization becomes near-perfect when each voice is its own file.
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 Riverside store its recordings?
After a session, download per-participant WAV/MP4 tracks from the recording page — that's the platform's whole point. Use the separate per-speaker tracks: diarization becomes near-perfect when each voice is its own file.
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.
