Hi,

I was trying to record a background music with a user's voice at the
same time. I did a playback and started recording. But the recorded
user's voice and the background music is about 0.5 second out of sync. I
also tried to use uuid_displace instead of playback, but I got the same
result.

I guess it was the transfer delay between freeswitch and the end user.
Is there a way to avoid that?

One of the solution that I can think of is to route the background music
to the end user and then route it back to freeswitch and let freeswitch
recorded user's voice and the routed music together. But I don't know
how I can do that in freeswitch.

Any idea?

Thanks.
Daniel

Can you show us an example of how you're doing this? Playback and
Record aren't async so you'll need to show us how you're doing this.

Also don't hijack threads you hit replay on the one "Re: [Freeswitch-
users] FreeSwitch setup as a "Dumb" SBC" as the subject, deleted the
subject and started a new body. That hijacks the thread and that can
cause your problem to go ignored in some cases if people aren't
interested in the thread topic depending on how their reader threads
the emails.

Please click new message and type freeswitch-

What I did was the following:

First, I sent the playback command:

call-command: execute
execute-app-name: playback
execute-app-arg: <filename>

Then I send uuid_record (Sorry, it was not Record command):

api uuid_record <uuid> start <filename> 120

I also tried replacing the playback command with:
api uuid_displace <uuid> start <filename> 0 mux

But the end results are the same. The recorded user's voice is about 0.5 second behind the expected result.

Thanks,
Daniel
