these are indices for acessing the mCoordinates array in struct AudioChannelDescription [@enum] AudioChannelCoordinateIndex Constants for indexing the mCoordinates array in an AudioChannelDescription structure. [@constant] kAudioChannelCoordinates_LeftRight For rectangulare coordinates, negative is left and positive is right. [@constant] kAudioChannelCoordinates_BackFront For rectangulare coordinates, negative is back and positive is front. [@constant] kAudioChannelCoordinates_DownUp For rectangulare coordinates, negative is below ground level, 0 is ground level, and positive is above ground level. [@constant] kAudioChannelCoordinates_Azimuth For spherical coordinates, 0 is front center, positive is right, negative is left. This is measured in degrees. [@constant] kAudioChannelCoordinates_Elevation For spherical coordinates, +90 is zenith, 0 is horizontal, -90 is nadir. This is measured in degrees. [@constant] kAudioChannelCoordinates_Distance For spherical coordinates, the units are described by flags.
