¶ Bases:
mutagen.StreamInfo
MPEG audio stream information
Parse information about an MPEG audio file. This also reads the Xing VBR header format.
This code was implemented based on the format documentation at http://mpgedit.org/mpgedit/mpeg_format/mpeghdr.htm.
Useful attributes:
-
length
¶ audio length, in seconds
- Type
float
-
channels
¶ number of audio channels
- Type
int
-
bitrate
¶ audio bitrate, in bits per second. In case
bitrate_mode
isBitrateMode.UNKNOWN
the bitrate is guessed based on the first frame.- Type
int
-
sample_rate
¶ audio sample rate, in Hz
- Type
int
-
encoder_info
¶ a string containing encoder name and possibly version. In case a lame tag is present this will start with
"LAME "
, if unknown it is empty, otherwise the text format is undefined.- Type
-
encoder_settings
¶ a string containing a guess about the settings used for encoding. The format is undefined and depends on the encoder.

class
mutagen.mp3.
BitrateMode
¶ -
UNKNOWN
= <BitrateMode.UNKNOWN: 0>¶ Probably a CBR file, but not sure
-
CBR
= <BitrateMode.CBR: 1>¶ Constant Bitrate
-
VBR
= <BitrateMode.VBR: 2>¶ Variable Bitrate
-
ABR
= <BitrateMode.ABR: 3>¶ Average Bitrate (a variant of VBR)

EasyMP3
(filething)¶ Bases:
mutagen.mp3.MP3
Like MP3, but uses EasyID3 for tags.
