How to send a listen-once audio message
4 min
Audio is the easiest message to keep and forward — which makes it the riskiest. With listen-once delivery the audio plays a single time and the file is destroyed, never sitting in a chat.
Record now or upload a file
You can record straight on the page with your device microphone, or upload a file you already have (MP3, M4A, OGG or WAV) up to 5 MB and 2 minutes.
After recording you can listen before sending and record again if you're not happy.
Choosing the channel
The audio link goes out by WhatsApp, anonymous SMS (Brazilian numbers) or email. In every case only a link arrives — the file is never attached to a chat.
How listen once works
On the first open the player is released and the file is marked as consumed. The same link won't play again on any device. Without an open, the audio expires in 24 hours.
Tips for a better recording
Simple things that save you from recording twice:
- Record somewhere quiet, with the phone close to your mouth.
- Be direct: short audio gets listened to all the way through.
- Avoid full names and details that identify other people.
Send your view-once photo, audio, video or text
Pick the content and the channel: the recipient opens it once and everything is erased.
