>> Hello Stefan!
>> Ecasound's basic concept is chains. A chain looks like this:
>> input -> possible processing options -> output
>> So you can use jack intput and output:
>> ecasound -f:16,2,44100 -i jack_multi,mpd:out1,mpd:out2 -o \
>> jack_multi,system:playback_1,system:playback_2
>> At the end of this line you can add effects. For example a filter. You
>> can
>> use LADSPA unique IDs or the labels. I prefer IDs, since I always forget
>> upper and lower case letters. So the GLAME Highpass IIR filter (label:
>> highpass_iir and ID 1890). It has two parameter cutoff and poles/stages.
>> You
>> can find that out with analyseplugin from the basic ladspa suite or look
>> it
>> up in your favourite graphic ladspa host. So at the end of the ecasound
>> line
>> we have:
>> -eli:1890,50,2
>> or
>> -el:highpass_iir,50,2
>> Adds a highpass filter with 50Hz cutoff frequency and two
>> stages/poles.
>> My favourite EQ is still Fons Adriaenson's 4-band parametric EQ
>> (1970). I
>> think the package is called 4-band parametric filter (or just filter).
>> It
>> has a lot of options, you can try them in your favourite graphical
>> application first and then copy all the values, that you found. probably
>> easiest for you.
>> If you need more help ask. - one last note: the -f:16,2,44100 is the
>> ecasound audio formation option, see the manpage. It's
>> bitrate,number-of-channels,samplerate. So this is CD-quality. Adapt to
>> your
>> needs.
>> Warmly yours
>> Julien
