1. wavinfo Quickstart
All metadata is read by an instance of WaveInfoReader
.
Each type of metadata, iXML, Broadcast-WAV etc. is accessible through scopes, properties on an
instance of WaveInfoReader
.
import wavinfo
path = 'path/to/your/wave/audio.wav'
info = wavinfo.WavInfoReader(path)
adm_metadata = info.adm
ixml_metadata = info.ixml
1.1. WavInfoReader Class Documentation
- class wavinfo.wave_reader.WavInfoReader(path, info_encoding='latin_1', bext_encoding='ascii')
Parse a WAV audio file for metadata.
- __init__(path, info_encoding='latin_1', bext_encoding='ascii')
Create a new reader object.
- Parameters:
path – A pathlike object or IO to the wav file you wish to probe or a file handle to an open file.
info_encoding – The text encoding of the
INFO
,LABL
