Audio Capture and Playback(Full duplex)

Hi all,

 

     I need to capture audio in playbook and play it back at the sametime. So is there a way to do that in Qt? Basically is 

the playbook supporting full duplex?. I tried Qt qmediaplayer examples but it didn't really worked out. Some errors were thrown on phonon support. Any suggestions??

 

 

Thanks,

Madhan

I too have same problem. There is delay between recording and playback. Any idea how to reduce the delay?

Re: Audio Capture and Playback(Full duplex)

You can use native audio support. Have a look at the playwave sample. Full duplex is supported on the playbook. So you should have no problem.

Hi, 

 

How far are you with your app? Are you able to open the capture device and received data?

 

Have you read SDK reference guides: https://developer.blackberry.com/native/reference/com.qnx.doc.neutrino.audio/topic/pcm.html ?
