FFMPEG Audio filters

[lafuente]

Thank,

So I tried :

stream.transcode : aiff:wav;, flac:wav;
This seem OK.

After, as sample, I tried :

stream.options : convOut=-lavfi equalizer=f=1000:t=q:w=1:g=2
Seem OK

Then I tried to add a second argument :
stream.options : convOut= -lavfi equalizer=f=1000:t=q:w=1:g=2,equalizer=f=100:t=q:w=2:g=-5
Not OK

Can someone point me where is my mistake ?

thank again
