# wavinfo
|
|
|
|
The `wavinfo` package allows you to probe WAVE and [RF64/WAVE files][eburf64] and extract extended metadata, with an emphasis on film, video and professional music production metadata.
|
|
|
|
|
|
## Metadata Support
|
|
|
|
`wavinfo` reads:
|
|
|
|
* [__Broadcast-WAVE__][ebu] metadata, including embedded program
|
|
loudness, coding history and [__SMPTE UMID__][smpte_330m2011].
|
|
* [__ADM__][adm] track metadata, including channel, pack formats, object and content names.
|
|
* [__iXML__][ixml] production recorder metadata, including project, scene, and take tags, recorder notes
|
|
and file family information.
|
|
* Most of the common [__RIFF INFO__][info-tags] metadata fields.
|
|
* The __wav format__ is also parsed, so you can access the basic sample rate and channel count
|
|
information.
|
|
|
|
In progress:
|
|
* [__Dolby RMU__][dolby] metadata and [EBU Tech 3285 Supplement 6][ebu3285s6].
|
|
* Pro Tools __embedded regions__.
|
|
* iXML `STEINBERG` sound library attributes.

## How To Use
|
|
|
|
The entry point for wavinfo is the WavInfoReader class.
|
|
|
|
```python
|
|
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:
|
|
|
|
```sh
|
|
$ wavinfo test_files/A101_1.WAV
|
|
```
|
|
|
