To get the bit rate of an MP3 file using FFmpeg, you can use the ffprobe command, which is a multimedia stream analyzer bundled with FFmpeg. Here's a command you can use:

ffprobe -v error -show_entries format=bit_rate -of default=noprint_wrappers=1:nokey=1 input.mp3

Replace input.mp3 with the path to your MP3 file.

This command will output the bit rate of the given MP3 file in bits per second (bps).

Explanation of the command:

-v error: Set the logging level to "error" to avoid unnecessary messages.

-showentries format=bitrate: Show only the bit rate information in the output.

-of default=noprint_wrappers=1:nokey=1: Set the output format to display just the value of the bit rate without additional formatting or metadata.

After running the command, you should see the bit rate of the MP3 file displayed in the terminal.

To display the bit rate in kilobits per second (kbps), you can modify the command slightly by using awk to perform the conversion. Here's the updated command:

ffprobe -v error -show_entries format=bit_rate -of default=noprint_wrappers=1:nokey=1 input.mp3 | awk '{print $1 / 1000 " kbps"}'
