Plivo has mentioned on their Voice SDK features that Plivo supports Dual-channel call recording and Recordings are dual-channel by default and stored encrypted. However I do not see where to get two different audio urls from the call recording.

Does anyone has idea how to do it?

Plivo makes mono recordings of conference calls and stereo recordings of regular calls. Having said that, for dual-channel recording(stereo) Plivo provides the audio of both the participants in separate channels.

You can listen to the audio of:

  • participant1 channel (the left speaker when played with stereo speakers).
  • participant2 channel (the right speaker when played with stereo speakers).

Hope this is helpful, please refer to our Record Calls guide for more details about the recording feature. Thanks!

  • I have also read it on Plivo documents, but there is no where they have written about how to retrieve audios of a separate channel. When i retrieve audio it just gives a single url which plays speaker 1 and speaker 2 voice together – Parth Pandya Jan 04 '22 at 06:41

    you should be able to split it using Audacity or some other audio editing tool. Refer: https://manual.audacityteam.org/man/splitting_and_joining_stereo_tracks.html – Nixon Samuel Jan 05 '22 at 07:30

    unfortunately, Plivo doesn't provide split audio files at the moment. However, you can achieve this using the [Multiparty Call feature](https://www.plivo.com/docs/voice/api/multiparty-call/) that enables to manage the [recording at a participant level](https://www.plivo.com/docs/voice/api/multiparty-call/participants/participant-level-recording#start-recording). You can also refer to the details in the detailed [use case guide](https://www.plivo.com/docs/voice/use-cases/supervisor-coaching/python). Thanks! – Nixon Samuel Jan 07 '22 at 07:06
