I want to save voices from a microphone which is connected to the Edison board by USB interface. But I totally don't have any idea in that.Can anyone help me and give me some advices?
I have a USB earphone, it has a microphone. I am planning to use that microphone. How can I get data from it through USB interface?
Earlier, I have installed alsa, mpg123 on yocto to play ".wav", ".mp3" audio files. And I have noticed that alsa has record function, can that be helpful?
One way to do this is using arecord
Take a look at this tutorial -> arecord Mini-Howto
For testing your setup, there is an instruction in there you can use:
root@edison:~# arecord -f dat -d 20 -D hw:0,0 test.wav
Be sure to be running the Release2.1 (version = 146)
I hope you find this helpful
