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__ metadata<sup>[1][ebu]</sup>, including embedded program
|
||||
loudness and coding history, if extant. This also includes the SMPTE UMID<sup>[2][smpte_330m2011]</sup>.
|
||||
* ADM track metadata<sup>[3][adm]</sup>, including channel, pack formats, object and content names.
|
||||
* __iXML__ production recorder metadata<sup>[4][ixml]</sup>, including project, scene, and take tags, recorder notes
|
||||
* [__Broadcast-WAVE__][ebu] metadata, including embedded program
|
||||
loudness and 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__<sup>[5][info-tags]</sup> metadata fields.
|
||||
* 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].
|
||||
* iXML `STEINBERG` sound library attributes.
|
||||
* __NetMix__ library attributes.
|
||||
* [__Dolby RMU__][dolby] metadata and [EBU Tech 3285 Supplement 6][ebu3285s6].
|
||||
* Pro Tools __embedded regions__.
|
||||
* iXML `STEINBERG` sound library attributes.

### Basic WAV Data
|
||||
|
||||
The length of the file in frames (interleaved samples) and bytes is available, as is the contents of the format chunk.
|
||||
|
||||
```python
|
||||
(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)
