sw_usb_audio with mono signal in 44100hz

Postby noop » Tue Aug 01, 2017 9:04 am

Hi all,
I am playing around with an xCore smart microphone array and the example implementation sw_usb_audio. I am testing all the examples in the Getting Started document.
The functions explained there work at a frequency of 16000hz and with two channels. I tried to change the Makefile to get this running at 44100hz and just a mono signal but was not successful in that.
In a first step after changing the MIN and MAX frequecies, the board showed a strange blinking behaviour. I think this is related to the 44100hz instead of 48000hz. What do I have to change additionally? The Illusonic voice stuff seems to have separate defines where frequency is 16000. But the voice got really disturbed.

Hi, its me again ...
I would really appreciate a Feedback, if the illusonic voice stuff only works with 16000Hz or what I need to change in order to get it running at another frequency.
Thank you and have a nice day.
