[MPlayer-users] correct syntax for combining filters

[Christian]

Hi all,

I´m looking for the right way to combine filters in *mplayer*.

I want to achieve the following:

I´d like to play a .wav-file with the *equalizer*-option set and the 
*higher-speed*-option (plus: *not altering the pitch* when playing
faster).

Man-pages say:

-af <filter1[=parameter1:parameter2:...],filter2,...>
               Setup a chain of audio filters.

Seems that´s what I´m looking for.

This command however doesn´t work:

mplayer -af scaletempo=scale=1.2:speed=pitch -srate 44100 -af 
lavcresample=44100 -af equalizer=0:0:0:0:0:0:0:0:7:7 test.wav

I.e.: the equalizer option does work (audio is much crisper) but it´s 
all played back at normal speed (not with the factor of "1.2").

Could anybody help me with the correct syntax?

Thanks a lot in advance.
Many greetings.
Rosika
