Hi all Well, I have discorer 4 months ago liquidsoap, and I am very happy with this powerful and smart software.
Meanwhile I am learning about LS and caml language, I was tried a lot of tweaking to improve sound processing in my no-gui centos server. I was tried all the LS own filters, like high-pass, low-pass, iir, etc. But making a big process use a lot of cpu resources. Better one is to use all PADSPA plugins that LS can handle! and use a little power of cpu. Look at http://ardour.eu/plugins or http://www.ladspa.org to know more about ladspa and plugins. Install through your package management system all the plugins you want, or compile those that your OS not have. One case is the calf multiband processor. Centos not have this package in repository, so I was compiled the latest calf plugin from the git repository. Here you have a 4 band compressor, with the settings I have using. You may need to tweak to your requirements. radio = ladspa.multibandcompressor( bypass=false, input=1., output=1., split_1_2=130., split_2_3=1500., split_3_4=7000., s1=-0.25, s2=-0.136, s3=-0.148, q1=0.90, q2=0.90, q3=0.90, threshold_1=0.211, ratio_1=2.5, attack_1=4., release_1=400., makeup_1=1.2, knee_1=1., detection_1=1, bypass_1=false, mute_1=false, threshold_2=0.300, ratio_2=2.5, attack_2=10., release_2=150., makeup_2=1.1, knee_2=3., detection_2=1, bypass_2=false, mute_2=false, threshold_3=0.260, ratio_3=2.5, attack_3=100., release_3=200., makeup_3=1.1, knee_3=2.75, detection_3=1, bypass_3=false, mute_3=false, threshold_4=0.145, ratio_4=2.5, attack_4=57., release_4=200., makeup_4=1.2, knee_4=2., detection_4=1, bypass_4=false, mute_4=false, radio ) Of course, you have a tons of plugins to made and creat effects or audio processing. If you want to preset prior to put in your LS script, you can use an audio software to run in your PC and add the plugin, and then copy the settings in you LS script. because I have a XP workstation, I am using Aqualung to implement the ladspa plugins in window$: http://aqualung.factorial.hu Please share your experience with ladspa plugins in LS.
