如何通过命令行查找 mp3 文件的比特率?

如何通过命令行查找 mp3 文件的比特率?

可以用来查找 mp3 文件的比特率的终端命令是什么?

除此之外还有其他可用选项吗mpg321 -t name.mp3

答案1

媒体信息是进一步的解决方案(不仅仅在 mp3 上)。

sudo apt-get install mediainfo

例子:

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

输出:

Bit rate mode                            : Constant
Bit rate                                 : 192 Kbps

另一个例子:

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

另一个输出:

Bit rate                                 : 192 Kbps

通过以下方式获取音频比特率媒体信息单位为bps:

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

或以 Kbps 为单位:

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

答案2

简单的说:

file song.mp3

笔记: file包含在 Ubuntu 中。


对于别名爱好者,请在文件末尾插入以下内容~/.bashrc

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

打开一个新的终端窗口。您现在可以运行以下命令:

bitrate song.mp3

答案3

安装mp3信息包裹

sudo apt-get install mp3info

要查找比特率,请使用

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

将提供您需要的信息,还有一些其他有用的功能man mp3info可供您了解更多信息

答案4

迄今为止最好的信息是由ffprobe(该包的一部分ffmpeg)提供的。mpg123也不错,但是很难 grep 输出,这可能就是你要求其他东西的原因。

$ 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

对于专业使用,请执行以下操作:

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