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

Raspberry Pi boards are capable of recording stereo audio using an interface called the inter-IC sound (I2S or I2S) bus. The I2S standard uses three wires to record data, keep track of timing (clock), and determine whether an input/output is in the left channel or right channel [read more on I2S here and here].
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
