Unable to run example of Audio Pitch Shift Using Audio Capture Playback on Raspberry Pi board.

Dear Sir/Ma'am,

I am trying to run the example of Audio Pitch Shift using Audio Capture Playback on Raspberry Pi board. For the same I have make setup as shown in the example and also follow the all instructions till deployement of code.

Also, I am getting a message of successful code generation.

As per the example, after successfull code generation it suppose to take input of the microphone and then need to process it for pitch shift and further provide it to 3.5mm jack (aux) port as a output.

In my case I am not getting any audio signal at output side.

I have verified my USB microphone and headphone on my PC and they are working properly.

Screenshot of successful code generation and set that I have prepared at my side are attached herewith.

Please help me to resolve this issue.

Thanks in advance!

Regards,

Mahesh Giri.

Hi Mahesh,

Can you confirm the 'DeviceName' value was set correctly? You can use "listAudioDevices" to get the device id.
