[pulseaudio-discuss] Fade-In/Fade-Out Effect

[Yogesh Sharma]

Hello All
        
How to get Fade-in/Fade-out effect using pulseaudio APIs.
As Arun says in Article
http://arunraghavan.net/2011/05/more-pulseaudio-power-goodness/
"PulseAudio doesn’t offer an API to do fades" , is there any way to get
fade effects in pulseaduio. 

And if pulseaudio does not support fade effect then what are these APIs
meant for pa_cvolume_get_fade(), pa_cvolume_set_fade() and
pa_cvolume_get_fade(). 
I tried to use these APIs but did not get any success.

Any suggestions will be very great help.

Regards
Yogesh
