FLAC¶
Read and write FLAC Vorbis comments and stream information.
Read more about FLAC at http://flac.sourceforge.net.
FLAC supports arbitrary metadata blocks. The two most interesting ones are the FLAC stream information block, and the Vorbis comment block; these are also the only ones Mutagen can currently read.
This module does not handle Ogg FLAC files.

FLAC
(filething)¶ Bases:
mutagen.FileType
A FLAC audio file.
Parameters: filething (filething) – -
pictures
¶ list[Picture] – list of embedded pictures
-
info
¶
-
static
score
(filename, fileobj, header_data)¶ Returns a score for how likely the file can be parsed by this type.
Parameters: Returns: - negative if definitely not a matching type, otherwise a score,
the bigger the more certain that the file can be loaded.
Return type: int
Add a Vorbis comment block to the file.
-
delete
(filething=None)¶ Remove Vorbis comments from a file.
If no filename is given, the one most recently loaded is used.
-
clear_pictures
()¶ Delete all pictures from the file.
-
save
(filething=None, deleteid3=False, padding=None)¶ Save metadata blocks to a file.
Parameters: - filething (filething) –
- deleteid3 (bool) – delete id3 tags while at it
- padding (
mutagen.PaddingFunction
) –
If no filename is given, the one most recently loaded is used.

StreamInfo
¶ FLAC stream information.
This contains information about the audio data in the FLAC file. Unlike most stream information objects in Mutagen, changes to this one will rewritten to the file when it is saved. Unless you are actually changing the audio stream itself, don’t change any attributes of this block.
-
min_blocksize
¶ int
– minimum audio block size
-
max_blocksize
¶ int
– maximum audio block size
-
sample_rate
¶ int
– audio sample rate in Hz
-
channels
¶ int
– audio channels (1 for mono, 2 for stereo)
-
bits_per_sample
¶ int
– bits per sample
-
total_samples
¶ int
– total samples in file
-
length
¶ float
– audio length in seconds
-
bitrate
¶ int
– bitrate in bits per second, as an int
Bases: mutagen.StreamInfo
-
pprint
()¶ Returns: text: Print stream information
-
-
class
mutagen.flac.
Picture
¶ Read and write FLAC embed pictures.
-
type
¶ id3.PictureType
– picture type (same as types for ID3 APIC frames)
-
width
¶ int
– width in pixels
-
height
¶ int
– height in pixels
-
depth
¶ int
– color depth in bits-per-pixel
-
colors
¶ int
– number of colors for indexed palettes (like GIF), 0 for non-indexed
To create a picture from file (in order to add to a FLAC file), instantiate this object without passing anything to the constructor and then set the properties manually:
p = Picture() with open("Folder.jpg", "rb") as f: pic.data = f.read() pic.type = id3.PictureType.COVER_FRONT pic.mime = u"image/jpeg" pic.width = 500 pic.height = 500 pic.depth = 16 # color depth

CueSheet
¶ Read and write FLAC embedded cue sheets.
Number of tracks should be from 1 to 100. There should always be exactly one lead-out track and that track must be the last track in the cue sheet.
-
media_catalog_number
¶ mutagen.text
– media catalog number in ASCII, up to 128 characters
-
lead_in_samples
¶ int
– number of lead-in samples
-
compact_disc
¶ bool
– true if the cuesheet corresponds to a compact disc
-
tracks
¶ list[CueSheetTrack] – list of CueSheetTrack objects
-
lead_out
¶ CueSheetTrack
orNone
– lead-out as CueSheetTrack or None if lead-out was not found
-
-
class
mutagen.flac.
CueSheetTrack
¶ A track in a cuesheet.
For CD-DA, track_numbers must be 1-99, or 170 for the lead-out. Track_numbers must be unique within a cue sheet. There must be atleast one index in every track except the lead-out track which must have none.
-
track_number
¶ int
– track number
-
start_offset
¶ int
– track offset in samples from start of FLAC stream
-
isrc
¶ mutagen.text
– ISRC code, exactly 12 characters
-
type
¶ int
– 0 for audio, 1 for digital data
-
pre_emphasis
¶ bool
– true if the track is recorded with pre-emphasis
-
indexes
¶ list[CueSheetTrackIndex] – list of CueSheetTrackIndex objects
-
-
class
mutagen.flac.
CueSheetTrackIndex
(index_number, index_offset)¶ Index for a track in a cuesheet.
For CD-DA, an index_number of 0 corresponds to the track pre-gap. The first index in a track must have a number of 0 or 1, and subsequently, index_numbers must increase by 1. Index_numbers must be unique within a track. And index_offset must be evenly divisible by 588 samples.
-
index_number
¶ int
– index point number
-
index_offset
¶ int
– offset in samples from track start
-
