Avaya ACRA how to enable stereo recording

[hymanchen]

version
cm10.1.3
aes 10.1.3
ACRA 15.2
I download the wav file still the mono ,but it had changed to stereo recording.I can't think of a better way to solve this issue.

Thanks all.

Check the recorder compression settings. If you have "mixed mono" enabled it will combine the stereo stream files into a single mono one

Thanks for reply. Recorder compression mixed mono not enabled. Was the Stereo function need to restart all the servers to make it work?

Nope, if it's an IP recorder it gets the audio as two streams and records it as stereo anyway.

Have a look at the Media drive and the latest Calls folder and make a test call, you should see 2x WAV files and an XML while the call is in progress and after hang-up it will change to a single WAV and XML

Assume you have installed a patch or HFR as I've never seen that "enable stereo recording" option under the registration pool before and the 15.2 docs have no reference to it.

Have a look at the latest release notes to see if there is any info about that being added and what it means.

I was restarted all the server .The changed was look like not working.
The downloaded audio is still mono, and the search recording has only one wave.
ACRA was installed 15.2_2021R1_Published_KBs-15.2.9.836
Thanks for your help!

Ah looks like I was wrong about dual streams, looks like DMCC MR sums the streams into a single one by default.

Found this for AES

https://documentation.avaya.com/bun...ent_and_Media_Tone_Announcement_for_DMCC.html

and the NICE manual also says that the stream is summed when using DMCC MR

This integration provides “muxed” (mono) audio and therefore does not support speaker separation for reporting or analytics.

Could be a R10 bug or missing option for CM or AES, I'd raise a ticket with Avaya.

2.Recorder server
general setup-integration adapters-settings-select dmcc adapter and restart
