Effects.MPXEnable method

Previous pageReturn to chapter overviewNext page

Remarks

 

Enables/disables the application of the MPX (Multiplex) DSP effect on the playing sound. A sound must be already loaded inside the given player before applying this method.

 

Multiplex is a type of Karaoke software that has specially formatted left and right channels to make multiplex features available. To be formatted for multiplex use, a disc must have the vocals coded to the right channel and the music to the left channel. When you enable the use of the MPX DSP, the control will attenuate/remove the right channel (vocals) and split the left channel (music) to both sides. Attenuation removal of the vocal channel can be fine-tuned using the Effects.MPXSetVocalAttenuation method.

 

With some special MPX file there may be the need to invert channels management: this can be done using the Effects.MPXInvertChannels method.

 

See the How to apply special effects to a playing sound section for further details.
