wavinfo

See the note below about version 3.

The wavinfo package allows you to probe WAVE and RF64/WAVE files and extract extended metadata. wavinfo has an emphasis on film, video and professional music production but aspires to be the encyclopedic and final source for all WAVE file metadata.

Metadata Support

wavinfo reads:

• All defined Broadcast-WAVE fields, including embedded program loudness, coding history and SMPTE UMID.
• iXML production recorder metadata, including project, scene, and take tags, recorder notes and file family information.
  • iXML STEINBERG sound library attributes.
• All known RIFF INFO metadata fields.
• Audio Definition Model (ADM) track metadata and schema, including channel, pack formats, object, content and programme, including Dolby Digital Plus and Dolby Atmos dbmd metadata for re-renders and mixdowns.
• Wave embedded cue markers, cue marker labels, notes and timed ranges as used by Zoom, iZotope RX, etc.
• The wav format is also parsed, so you can access the basic sample rate and channel count information.

How To Use

The entry point for wavinfo is the WavInfoReader class.

from wavinfo import WavInfoReader

path = '../tests/test_files/A101_1.WAV'

info = WavInfoReader(path)

adm_metadata = info.adm
ixml_metadata = info.ixml

The package also installs a shell command:

$ wavinfo test_files/A101_1.WAV

Version 3 Coming Soon!

Version 3 is under active development and will be released in the near future. Version 3 will support editing of Broadcast-WAVE and INFO metadata, with more formats to be added.

There will be some minor breaking changes with the interface which is why I'm bumping to version 3, these will be documented and should be easy to update for.
