Creating a waveform graph of audio recorded with AudioRecorder

HI all,

 

I want to to display a waveform, similiar to the Sound Recorder in Windows, while recording audio with AudioRecorder.  Is it possible?  I don't see anyway to get acess to the audio data as its being recorded.  Do I need to use the sound functions in the native sdk instead of the Cascades stuff?

 

If the only way to do it is with the C functions from the native sdk, is it possible to use the the Cascades stuff I already have working in conjunction with the C functions?

 

Any help or examples would be greatly appreciated.

 

Thanks

Did you get a solution for this? 

 

I figure it's "easily" possible with the Core Native, possibly by reading the bytes inside the file. 

Most probably this will need to be generated into a bitmap for performance.

If it can be done in native it should be also possible in Cascades.

 

Probably this docs should help: https://developer.blackberry.com/native/documentation/bb10/com.qnx.doc.neutrino.audio/topic/pcm_capt...

 

I know that Scoreloop, which is available for Native Framework, can be also used in Cascades.
