The VLC Graphical Equaliser<\/h2>\n
Play your CD and adjust the equaliser settings in the VLC equaliser until your mix is satisfactory. Find this by pressing Here is an example of how to invoke VLC from the command line to equalise a stream to a file called The three most important options to note are the Now that you have the example command, let’s put the command into a script so that you can conveniently convert a whole CD without a lot of retyping. We will parameterise the track number and the name of the output file, but not the equaliser settings. If you need custom equaliser settings for every track, then by adapting this example you can parameterise the equaliser also. This script uses the FAAC encoder to save the That’s it! In the example above I added line breaks for clarity; if you get errors then you might need to remove them.<\/p>\n The author acknowledges the traditional custodians of the Daruk and the VLC\u00ae is a registered trademark of the VideoLAN non-profit organisation.<\/p>\n","protected":false},"excerpt":{"rendered":" Introduction Suppose you have some music on a CD or an online streaming source that you want to copy to your computer for personal listening.

When you have found the equaliser settings that you want, such as is shown in the screenshot below, the question is: how do you translate these into a command that will work when you stream the file? It is not simple enough to save these settings, quit VLC, then run a script, since that will not work. When you have found the settings you want, write down on the numbers for the Preamp and the frequency bands, including those you left at 0, and get ready to use them on the command line.<\/p>\n![\"VLC](\"\/wp-content\/uploads\/2023\/06\/VLC_equaliser_screenshot.png\")
