What is the terminal command that can used to find the bitrate of an mp3 file?

Is there any other option available other than mpg321 -t name.mp3?

MediaInfo is further solution to do that (not only on mp3).

sudo apt-get install mediainfo

Example:

mediainfo Aphrodite_-_Superman_\(dnb\).mp3 | grep "Bit rate"

Output:

Bit rate mode                            : Constant
Bit rate                                 : 192 Kbps

Another Example:

mediainfo Aphrodite_-_Superman_\(dnb\).mp3 | grep 'Bit rate  '

Another Output:

Bit rate                                 : 192 Kbps

Get exactly the audio bitrate via mediainfo in bps: 

mediainfo --Output='Audio;%BitRate%' '/MY/MEDIA/FILE.MP3'

or in Kbps: 

mediainfo --Output='Audio;%BitRate/String%' '/MY/MEDIA/FILE.MP3'

Simply put:

file song.mp3

Note: file is included with Ubuntu.

For alias lovers, insert this at the end of your ~/.bashrc file:

bitrate () {
    echo `basename "$1"`: `file "$1" | sed 's/.*, \(.*\)kbps.*/\1/' | tr -d " " ` kbps
}

Open a new Terminal window. You may now run the following command:

bitrate song.mp3

Install mp3info package 

sudo apt-get install mp3info

To find the bitrate use

mp3info -r a -p "%f %r\n" *.mp3

will give the info you need, also has some other useful functions man mp3info for more info

You can install the package libimage-exiftool-perl:

sudo apt-get install libimage-exiftool-perl

Then run:

exiftool -AudioBitrate GoldLion.mp3

It will output something like:

Audio Bitrate : 192 kbps

The best info, by-far, is provided by ffprobe (part of the ffmpeg package). mpg123 is also nice, but hard to grep output, which is probably why you were asking for something else.

$ mpg123 -t example.mp3 2>&1 | grep -A1 -E "^MPEG"
MPEG 2.5 L III cbr32 11025 mono

$ ffprobe example.mp3 2>&1 | grep Stream
    Stream #0:0: Audio: mp3, 11025 Hz, mono, s16p, 32 kb/s

For pro-use, do this:

# ffprobe -v quiet -print_format json -show_format -show_streams example.mp3
