What is "puddletag"

Puddletag is an audio tag editor, i.e. a metadata editor for audio file formats.

Under the hood it utilizes Mutagen, a Python module to handle audio metadata. Mutagen supports ASF, FLAC, M4A, APE, MP3, MPC, Ogg Opus, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, WavPack, OptimFROG, and AIFF audio files. All versions of ID3v2 are supported, and all standard ID3v2.4 frames are parsed. It can read Xing headers to accurately calculate the bitrate and length of MP3s. ID3 and APEv2 tags can be edited regardless of audio format. It can also manipulate Ogg streams on an individual packet/page level.

The user interface is very similar to that of Mp3tag, it uses a spreadsheet-like layout so that all the tags a user may want to edit by hand are visible and easily editable. All the other audio taggers available for Linux take a different approach to user interface design.

Puddletag is written in Python 2.x and uses Qt 4 (through PyQt) for its user interface. Mutagen works on Python 2.6, 2.7, 3.3, 3.4 (CPython and PyPy) and has no dependencies outside the Python standard library.

It includes support for the following audio formats: AAC, MPEG-4 (mp4/m4a/m4b/ iTunes compatible), OGG, OptimFROG OFR, OFS, SPX, TAK, TTA, WMA, WV.
