The BASS_CHANNELINFO type exposes the following members.

	Name	Description
	BASS_CHANNELINFO	Default constructor.

	Name	Description
	Is32bit	Gets, if the flags property contains the BASS_SAMPLE_FLOAT resp. BASS_MUSIC_FLOAT flag.
	Is8bit	Gets, if the flags property contains the BASS_SAMPLE_8BITS resp. BASS_MUSIC_8BITS flag.
	IsDecodingChannel	Is the channel a decoding channel?

	Name	Description
	ToString	A description of the decive info object (driver file name, inputs etc.). (Overrides ObjectToString.)

	Name	Description
	chans	Number of channels... 1=mono, 2=stereo, etc.
	ctype	The type of channel it is, which can be one of the following (see BASSChannelType), or another value if it's an add-on format (see the add-on's API). BASS_CTYPE_SAMPLE Sample channel. (HCHANNEL) BASS_CTYPE_STREAM User sample stream. This can also be used as a flag to test if the channel is any kind of HSTREAM. BASS_CTYPE_STREAM_OGG OGG VORBIS format file stream. BASS_CTYPE_STREAM_MP1 MP1 format file stream. BASS_CTYPE_STREAM_MP2 MP2 format file stream. BASS_CTYPE_STREAM_MP3 MP3 format file stream. BASS_CTYPE_STREAM_AIFF Audio IFF format stream. BASS_CTYPE_STREAM_CA CoreAudio codec stream. Additional information is avaliable via the BASS_TAG_CACODEC tag. BASS_CTYPE_STREAM_MF Media Foundation codec stream. Additional format information is avaliable from BASS_ChannelGetTags(Int32, BASSTag) (BASS_TAG_WAVEFORMAT). BASS_CTYPE_STREAM_WAV WAVE format flag. This can be used to test if the channel is any kind of WAVE format (LOWORD contains the codec number). BASS_CTYPE_STREAM_WAV_PCM WAV format file stream, PCM. BASS_CTYPE_STREAM_WAV_FLOAT WAV format file stream, Floating-Point. BASS_CTYPE_MUSIC_MOD MOD format music. This can also be used as a flag to test if the channel is any kind of HMUSIC. BASS_CTYPE_MUSIC_MTM MTM format music. BASS_CTYPE_MUSIC_S3M S3M format music. BASS_CTYPE_MUSIC_XM XM format music. BASS_CTYPE_MUSIC_IT IT format music. BASS_CTYPE_MUSIC_MO3 MO3 format flag, used in combination with one of the BASS_CTYPE_MUSIC types. BASS_CTYPE_RECORD Recording channel. (HRECORD) Other channel types may be supported by add-ons, see the documentation.
	filename	The filename associated with the channel. (HSTREAM only)
	flags	BASS_SAMPLE/STREAM/MUSIC/SPEAKER flags. A combination of these flags (see BASSFlag): BASS_SAMPLE_8BITS The channel's resolution is 8-bit. If neither this or the BASS_SAMPLE_FLOAT flags are present, then the channel's resolution is 16-bit. BASS_SAMPLE_FLOAT The channel's resolution is 32-bit floating-point. BASS_SAMPLE_LOOP The channel is looped. BASS_SAMPLE_3D The channel has 3D functionality enabled. BASS_SAMPLE_SOFTWARE The channel is NOT using hardware mixing... it doesn't benefit from any special hardware interpolation, etc. BASS_SAMPLE_VAM The channel is using the DX7 voice allocation and management features. (HCHANNEL only) BASS_SAMPLE_MUTEMAX The channel is muted when at (or beyond) it's max distance. (HCHANNEL) BASS_SAMPLE_FX The channel has the "with FX flag" DX8 effects implementation enabled. (HSTREAM/HMUSIC) BASS_STREAM_RESTRATE The internet file download rate is restricted. (HSTREAM) BASS_STREAM_BLOCK The internet file (or "buffered" user file) is streamed in small blocks. (HSTREAM) BASS_STREAM_AUTOFREE The channel will automatically be freed when it ends. (HSTREAM/HMUSIC) BASS_STREAM_DECODE The channel is a "decoding channel". (HSTREAM/HMUSIC) BASS_MUSIC_RAMP The MOD music is using "normal" ramping. (HMUSIC) BASS_MUSIC_RAMPS The MOD music is using "sensitive" ramping. (HMUSIC) BASS_MUSIC_SURROUND The MOD music is using surround sound. (HMUSIC) BASS_MUSIC_SURROUND2 The MOD music is using surround sound mode 2. (HMUSIC) BASS_MUSIC_NONINTER The MOD music is using non-interpolated mixing. (HMUSIC) BASS_MUSIC_FT2MOD The MOD music is using FastTracker 2 .MOD playback. (HMUSIC) BASS_MUSIC_PT1MOD The MOD music is using ProTracker 1 .MOD playback. (HMUSIC) BASS_MUSIC_POSRESET All notes will be stopped when seeking in the MOD music. (HMUSIC) BASS_MUSIC_POSRESETEX All notes will be stopped and BPM/etc reset when seeking in the MOD music. (HMUSIC) BASS_MUSIC_STOPBACK The MOD music will be stopped when a backward jump effect is played. (HMUSIC) BASS_SPEAKER_xxx Speaker assignment flags. (HSTREAM/HMUSIC) BASS_UNICODE A filename, command-line or argument is a Unicode (UTF-16) string. Other flags may be supported by add-ons, see the documentation.
	freq	Default playback rate.
	origres	The original resolution (bits per sample)... 0 = undefined.
	origresIsFloat	Is the original resolution floating point?
	plugin	The plugin that is handling the channel... 0 = not using a plugin. Note this is only available with streams created using the plugin system via the standard BASS stream creation functions, not those created by add-on functions. Information on the plugin can be retrieved via BASS_PluginGetInfo(Int32).
	sample	The sample that is playing on the channel. (HCHANNEL only)

Each "Channel" function can be used with one or more of these channel types.

The BASS_SAMPLE_SOFTWARE flag indicates whether or not the channel's sample data is being mixed into the final output by the hardware. It does not indicate (in the case of a stream or MOD music) whether the processing required to generate the sample data is being done by the hardware, this processing is always done in software.

BASS supports 8/16/32-bit sample data, so if a WAV file, for example, uses another sample resolution, it'll have to be converted by BASS. The origres member can be used to check what the resolution originally was.

BASS_CHANNELINFO info = new BASS_CHANNELINFO();
Bass.BASS_ChannelGetInfo(channel, info); // get info
if (info.ctype == BassChannel.BASS_CTYPE_STREAM_MP3) 
{
    // it's an MP3!
}
