Downmixes from stereo to mono file for mono encoding in OGG Vorbis format.
Important note Starting from version 8 of the component, this property is ignored until the usage of default internal encoders is enabled: see the EnableInternalEncoders method for details about disabling internal encoders.
This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_OGG.
This property is the same as entering the --downmix setting inside the Appendix B - OggEnc command line.
For further details about encoding in OGG Vorbis format refer to the EncodeOGG class section.
For further information about available encoding formats see the EncodeFormatsMan class.
