---------------------------------
Summary: Mp3Parser extracts wrong number of channels
Key: TIKA-990
URL: https://issues.apache.org/jira/browse/TIKA-990
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.2
Reporter: Oliver Heger
In class {{AudioFrame}} the last two bits of the MPEG frame header are used to
determine the number of channels. According to my documentation, this
information is encoded in bits 7 and 6.
I did a cross check with the ID3 tag editor tool ID3-TagIT
(http://www.id3-tagit.de/). The unit tests expect that the test MP3 files have
2 channels. However, the tool reports that the files are mono.
