The wavinfo package allows you to probe WAVE and RF64/WAVE files and extract extended metadata, with an emphasis on film, video and professional music production metadata.
wavinfo reads:
- Broadcast-WAVE metadata, compliant with EBU Tech 3285v2 (2011), including embedded program loudness and coding history, if extant. This also includes the SMPTE 330M UMID Unique Materials Identifier.
- iXML production recorder metadata, including project, scene, and take tags, recorder notes and file family information.
- Most of the common RIFF INFO metadata fields.
- The wav format is also parsed, so you can access the basic sample rate and channel count information.
In progress:
- iXML
STEINBERGsound library attributes. - Pro Tools embedded regions.
The entry point for wavinfo is the WavInfoReader class.
from wavinfo import WavInfoReader
path = '../tests/test_files/A101_1.WAV'
info = WavInfoReader(path)The length of the file in frames (interleaved samples) and bytes is available, as is the contents of the format chunk.
(info.data.frame_count, info.data.byte_count)
>>> (240239, 1441434)
(info.fmt.sample_rate, info.fmt.channel_count, info.fmt.block_align, info.fmt.bits_per_sample)
>>> (48000, 2, 6, 24)- For other file formats and ID3 decoding, look at audio-metadata.
