Hi<div>Code is quite experimental but I intend to release it asap (probably within a few weeks)</div><div>Let's see how it goes</div><div><br></div><div>Regards</div><div>Paulo</div><div><div><br><hr id="stopSpelling">Date: Fri, 28 Jan 2011 08:48:51 -0500<br>From: vipkilla@gmail.com<br>To: freeswitch-users@lists.freeswitch.org<br>Subject: Re: [Freeswitch-users] Portaudio Improvements<br><br>It would be very cool to be able to send audio to portaudio from another program using something like PulseAudio.

Wow, I didn't even know that somebody is working on PA2.<br>Paulo, could you share some more information about that module? Why would somebody use it instead of the current one? Advantages/disadvantages?<br>Is the source code available somewhere? Do you have a roadmap for the module? :)<br>

<div>Hi</div><div>You can try PortMixer for volume control that is intended to work along with PortAudio </div><div><br></div><div>I am developing/testing "mod_portaudio2" that does not rely on pablio, maybe things will be better with this approach</div>

Subject: Re: [Freeswitch-users] Portaudio Improvements<div><div></div><div><br><br>Ah well viewing volume levels had not been something I had looked into. It wouldn't be too hard but the question is how do you constantly report that (FS event every second? every half second? port audio commands to return that value frequently?). If your client is windows however again the native windows volume handler for apps does also keep track of their current output. <br>

Thanks Mitch, I actually had tried the equivalent uuid_audio and looks<br>
like it's the only way to do it for now. We had wanted to get energy<br>
levels dynamically to show a live indication but we given up that<br>
feature.<br>
