We have a customer who wants us to record anywhere from 2-4 participants on a call in stereo (as opposed to mono) quality audio.

Some background.. We are using asterisk 16.6.1
We are also currently using AMI/AsyncAGI and ConfBridge to bring the parties together. I believe recording in the various file formats (based on extension), it’s always recording in mono quality.

My one thought is to transition to using ARI Bridge (instead of ConfBridge) and streamed audio using ExternalMedia. Then have a media server capture the external media packets, stripping the payload information and write directly to a file. Would that audio be of ulaw stereo or mono?

Any suggestions?

  • I’m assuming you mean you want to get one stereo recording for each participant, where the left channel is the participant and the right channel is the rest of the conference?

    If that’s not correct, what do you want the two channels of a stero recording to contain?

    Suppose it *is* stereo – what would you expect the two channels to contain?
    It sounds like you want one single stereo recording of a conference with multiple participants. Are they all using stereo telephones and generating two-channel audio into the conference – or what??

    How about a simple MixMonitor with btr options on each participant who dials in, before they get placed into the conference? Then the t channel should be the participant and the r channel should be the rest of the conference.

    Regards,

    Antony.

  • Thank you Anthony

    I was not involved in the entire conference call with the customer. They plan to send the recordings to another company to anaylze the operators behavior. I believe you are correct about them left channel of the recording to be the operator and the right channel to be the 1-3 other participants (from ConfBridge).

    I will give the MixMonitor a try.

    Have a great day!
