如何通过命令行找到mp3文件的比特率?
什么是可用于查找mp3文件比特率的终端命令?
除了mpg321 -t name.mp3
之外还有其他选择吗?
简单的说:
file song.mp3
注意:
file
包含在Ubuntu中。
对于别名爱好者,请在~/.bashrc
文件的末尾插入:
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
安装mp3info包
sudo apt-get install mp3info
找到比特率使用
mp3info -ra -p "%f %r\n" *.mp3
将提供您需要的信息,还有一些其他有用的functionman mp3info
获取更多信息
MediaInfo是进一步解决方案(不仅在mp3上)。
sudo apt-get install mediainfo
例:
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bps中的mediainfo获取完全音频比特率:
mediainfo --Output='Audio;%BitRate%' '/MY/MEDIA/FILE.MP3'
或以Kbps为单位:
mediainfo --Output='Audio;%BitRate/String%' '/MY/MEDIA/FILE.MP3'
你可以安装包libimage-exiftool-perl
:
sudo apt-get install libimage-exiftool-perl
然后运行:
exiftool -AudioBitrate GoldLion.mp3
它将输出如下内容:
Audio Bitrate : 192 kbps
到目前为止,最好的信息由ffprobe
( ffmpeg
包的一部分)提供。 mpg123也不错,但很难grep输出,这可能是你要求别的东西的原因。
$ 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
如需使用,请执行以下操作:
# ffprobe -v quiet -print_format json -show_format -show_streams example.mp3 { "streams": [ { "index": 0, "codec_name": "mp3", "codec_long_name": "MP3 (MPEG audio layer 3)", "codec_type": "audio", "codec_time_base": "1/11025", "codec_tag_string": "[0][0][0][0]", "codec_tag": "0x0000", "sample_fmt": "s16p", "sample_rate": "11025", "channels": 1, "channel_layout": "mono", "bits_per_sample": 0, "r_frame_rate": "0/0", "avg_frame_rate": "0/0", "time_base": "1/14112000", "start_pts": 0, "start_time": "0.000000", "duration_ts": 55294344, "duration": "3.918250", "bit_rate": "32000", "disposition": { "default": 0, "dub": 0, "original": 0, "comment": 0, "lyrics": 0, "karaoke": 0, "forced": 0, "hearing_impaired": 0, "visual_impaired": 0, "clean_effects": 0, "attached_pic": 0, "timed_thumbnails": 0 } } ], "format": { "filename": "example.mp3", "nb_streams": 1, "nb_programs": 0, "format_name": "mp3", "format_long_name": "MP2/3 (MPEG audio layer 2/3)", "start_time": "0.000000", "duration": "3.918250", "size": "17260", "bit_rate": "35240", "probe_score": 51, "tags": { "title": "Sound Effects - Female Operatic La 1 - Opera singer sings La.", "artist": "Download Sound Effects - SoundDogs - AOS", "album": "http://www.Sounddogs.com", "track": "0", "copyright": "(c) 2010 Sounddogs.com, All Rights Reserved", "genre": "SFX - Humans; Vocalizations", "comment": "Royalty Free Sound Effects - Sounddogs.com", "date": "2008" } } }
