[Freeswitch-users] Audio clicks between playback of audio files
I'm implementing an IVR solution for FreeSWITCH, but I have a little problem with audio playback. I'm just calling into application park, and then handle the flow using the event socket. All my audio phrases are .PCMA (8KHz a-law), and I play lots of files after eachother. Between each file I can sometimes here a little click, even though I'm 100% sure that this is not from my files. My guess is that it might be caused of the fact that no RTP is sent at all when the phrase is not playing. If I merge the files together before playing them it sounds just fine. Is it possible to make FreeSWITCH send silence frames, even when not needed? I know this is a waste of resources, but it will still make the solution sound much better.

Have you tried wav files? /b On May 11, 2009, at 8:34 AM, Peter Olsson wrote: I’m implementing an IVR solution for FreeSWITCH, but I have a little problem with audio playback.

Re: [Freeswitch-users] Audio clicks between playback of audio files
Brian, Thanks for the response. No, I didn't try wav files - and I'd prefer to keep the current codec if that's possible. But I could give it a try and see what happens. Do you think it might only be related to the native files in FS? //Peter Från: freeswitch-users-boun...@lists.freeswitch.org [mailto:freeswitch-users-boun...@lists.freeswitch.org] För Brian West Skickat: den 11 maj 2009 16:09 Till: freeswitch-users@lists.freeswitch.org Ämne: Re: [Freeswitch-users] Audio clicks between playback of audio files Have you tried wav files? /b On May 11, 2009, at 8:34 AM, Peter Olsson wrote: I'm implementing an IVR solution for FreeSWITCH, but I have a little problem with audio playback.

I'm not sure. Can you provide me a test file and a known case that you can produce this issue with? /b On May 11, 2009, at 9:20 AM, Peter Olsson wrote: Brian, Thanks for the response.

Re: [Freeswitch-users] Audio clicks between playback of audio files
The problem is that it's not 100% reproducable. Sometimes I can play 2-3-4 files, and it sounds great, sometimes it clicks louder, somtimes not so much. I could get a Wireshark dump for you, could that help?

Re: [Freeswitch-users] Audio clicks between playback of audio files
In this case I'm using Avaya Phones connected to a Avaya CM PBX, which talks SIP to FreeSWITCH. But I'll try to connect a SIP phone directly as well - to see if it makes any difference. I Have a Polycom IP550 I can use for some testing. I've used the exact same setup using yate, and that worked fine, but I think one difference is that it sends rtp even when not playing files, so that's why I thought that could be an issue. /Peter Från: freeswitch-users-boun...@lists.freeswitch.org [mailto:freeswitch-users-boun...@lists.freeswitch.org] För Brian West Skickat: den 11 maj 2009 16:43 Till: freeswitch-users@lists.freeswitch.org Ämne: Re: [Freeswitch-users] Audio clicks between playback of audio files What phone are you using? /b On May 11, 2009, at 9:40 AM, Peter Olsson wrote: The problem is that it's not 100% reproducable.
