Remarks

This method first evaluates the BASS_CTYPE_xxx for the stream, by calling the BASS_ChannelGetInfo(Int32, BASS_CHANNELINFO) function internally. Based on the retrieved BASSChannelType a call to the BASS_ChannelGetTags(Int32, BASSTag) function is made in order to retrieve the pointer to the tags/header data - if available. Finally this tag pointer is evaluated and the related tag/header data is evaluated.

This method is able to retrieve the following TAGs:

MP3, MP2, MP1BASS_TAG_ID3V2 first, then BASS_TAG_ID3, then BASS_TAG_APE, then BASS_TAG_RIFF_BEXT.
OGG, FLAC, OPUSBASS_TAG_OGG first, then BASS_TAG_APE
WAV, BWFBASS_TAG_RIFF_INFO first, then BASS_TAG_RIFF_BEXT.
