Hi!<div><br></div><div>I'm trying to enable DRC through LADSPA plugins, I found a solution that work very well using dysonCompress and fastLookaheadLimiter with alsa, here are the details:</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://alsa.opensrc.org/index.php/Ladspa_(plugin)">http://alsa.opensrc.org/index.php/Ladspa_(plugin)</a></div>
<div><br></div><div><a href="http://alsa.opensrc.org/index.php/Ladspa_(plugin)"></a>The problem with alsa is that I was unable to use surround (5.1) with this config. As pulseaudio supports LADSPA plugins I'm trying to use this two plugins</div>
<div><br></div><div>The dysonCompressor works fine, I'm using this config:</div><div><br></div><div><div>load-module module-ladspa-sink sink_name=ladspa_output.dyson_compress_1403.dysonCompress master=alsa_output.pci-0000_00_05.0.analog-surround-51 plugin=dyson_compress_1403 label=dysonCompress control=0,1,0.5,0.99</div>
<div><br></div><div>With only this filter, a volume change takes effect after seconds/minutes, very annoying.</div><div><br></div><div>According with the pulseaudio wiki ladspa module only supports plugins with only one input:</div>
<div>"Currently this module only works with plugins that have one audio input port named "Input" and one output with name "Output". Patches welcome!"</div><div>So this may be the problem, FastLookaheadLimiter has two inputs:</div>
<div><br></div><div>analyseplugin /usr/lib/ladspa/fast_lookahead_limiter_1913.so </div><div>Ports:<span class="Apple-tab-span" style="white-space:pre"> </span>"Input gain (dB)" input, control, -20 to 20, default 0</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>"Limit (dB)" input, control, -20 to 0, default 0</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>"Release time (s)" input, control, 0.01 to 2, default 0.5075</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>"Attenuation (dB)" output, control, 0 to 70</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>"Input 1" input, audio</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>"Input 2" input, audio</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>"Output 1" output, audio</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>"Output 2" output, audio</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>"latency" output, control</div><div><br></div><div>Is there something I can do to make this plugin work?</div><div><br></div><div>Thank you in advance</div>
