Note: Windows users have to use the -option-name="value" syntax instead of the -option-name value syntax. You need to be quite comfortable with command line usage to use this.

Here is the complete description of VLC's command line and how to use it. However, some complex operations can only be done from the command line and there are situations in which you don't need or want a GUI. 3.2 Opening a DVD or VCD, or an audio CDĪll standard operations of VLC should be available from the GUI.I would even suggest that you try one of the other compressors, that seem better documented, like sc4. "Compression ratio" input, control, 0 to 1, default 0.5 "Fast compression ratio" input, control, 0 to 1, default 0.5 "Release time (s)" input, control, 0 to 1, default 0.25 Ports: "Peak limit (dB)" input, control, -30 to 0, default 0 The plugin itself suggests control=0,0.25,0.5,0.5 $ analyseplugin /usr/lib/ladspa/dyson_compress_1403.so So how could you all say what you should input as the last two values? The author of the package doesn't know what the last two values control. Source: settings above were adapted to pulseaudio from brien's blog on miscfitsĪlong with an alternative, I have some comments to the solutions above that suggest using the dysoncompressor.įrom the manual: 2.37 Dyson compressor (dysonCompress, 1403)Ĭontrols the desired limit of the output signal in dB's.Ĭontrols the time taken for the compressor to relax its gain control over the input signal. We may use the fast_lookahead_limiter for this with the master sink being now our just created lasdpa_sink from above: pacmd load-module module-ladspa-sink sink_name=ladspa_normalized master=ladspa_sink plugin=fast_lookahead_limiter_1913 label=fastLookaheadLimiter control=10,0,0.8 To avoid clipping of playback we may also combine this plugin with a limiter after compression.
See in the plugin documentation for more details, defaults and minimal resp maximal values for these controls. The compressed output can now be heard on the newly created output sink ladspa_sink accessible from the Sound Settings menu.Ĭontrol settings for the compressor plugin are as follows: peak limit, release time, fast ratio, ratio. Replace with the exact name of the output sink (in my system this was alsa_output.pci-0000_00_14.2.analog-stereo).
