Summary0001470: Multi-channel Ogg Vorbis sample import results in garbled sample data
Description

Some Ogg Vorbis files fail to import properly in the latest testing version. It seems that single-channel files are not affected by this bug—at least, none of the mono samples that I imported were affected. The result of this bug is a sample that is visibly distorted, does not last as long as it should, and is basically totally unusable. It does not seem like the encoder, quality and other parameters, etc. matter.

Steps To Reproduce
  1. Import a multi-channel Ogg Vorbis sample.
  2. The sample should sound (and look) strangely distorted.
Additional Information

Attached is a compressed folder containing some example Ogg Vorbis files which I produced, and the result of importing them and then re-saving them in WAV format. All the Vorbis files are 44.1kHz, quality 6.0. I encoded a stereo example with two different encoders (see metadata); I did not bother to do this for the mono one.

TagsNo tags attached.
