Capture/Record Audio Input in RaspberryPi

I bought a USB Audio Controller for RaspberryPi, in order to capture Audio input. I already done below steps on Rasbian but still unsure about Audio Capturing. Can you please guide me on how do I get it?

Type the following commands to install the Audio device

pi@raspberrypi ~ $ sudo apt-get install alsa-utils

Detection Successfully by

pi@raspberrypi ~ $ lsusb
pi@raspberrypi ~ $ amixer
pi@raspberrypi ~ $ alsamixer

Also configure USB Audio device to make it default

/etc/modprobe.d/alsa-base.conf

by adding pound/hash symbol with

options snd-usb-audio index=2
#options snd-usb-audio index=2
Solution

  • simply write this command of Command Terminal, in order to record Audio

    arecord -f cd -D plughw:0 -d 10 a.wav

    Let me know if you get further any issue in recording sound
