Crackling sound on alsa setup

Hey everyone can someone help me out with this one? I have this setup I'm trying to do here its alsaequal and some sort of loudness equalization but I'm trying to make these two work together.
But when I try to play something with this setup it sounds all crackling and unrecognizable! Here's the setup

defaults.pcm.rate_converter "speexrate_best"

ctl.equal {
      type equal;
}

pcm.equal {
      type equal;
      #slave.pcm "plughw:0,0";
      # using dmix allows multiple apps to use the sound card simultaneously
      slave.pcm "plug:dmix"
}

pcm.ladcomp_compressor {
    type ladspa
    slave.pcm "ladcomp_limiter";
    path "/usr/lib/ladspa";
    plugins [{
        label dysonCompress
        input {
            #peak limit, release time, fast ratio, ratio
            controls [0 1 0.5 0.99]
        }
    }]
}

pcm.ladcomp_limiter {
    type ladspa
    slave.pcm "equal";
    #slave.pcm "plug:dmix";
    path "/usr/lib/ladspa";
    plugins [{
        label fastLookaheadLimiter
        input {
            #InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release time (s) 0.01 -> 2
            #####controls [ 20 0 0.8  ]
			controls [ 20 0 0.8  ]
        }
    }]
}


pcm.!default {
    type plug;
    slave.pcm "ladcomp_limiter";
}

Can somebody please tell me why this is happening?
