L+R, L-R Mixer?

One of the many features of Cool Edit which I miss is the mixer. You could do additive mixing – adding a little left channel into the right – or subtractive editing – moving the center signal out to the wings – with just a touch of the slider.

I haven’t found anything like that in Audacity. Am I not looking in the right place?

I also came from CoolEdit, and missed that feature, so I made a “Channel Mixer” plug-in that is now available on the Audacity wiki: https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Channel_Mixer
Instructions for installing “Nyquist plug-ins” on macOS: https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_mac_os_x.html#nyquist_install

Cool, you are my new best friend.

Except I can’t get it to install.

The wiki says “To install new Nyquist plug-ins, place them in Audacity’s “Plug-Ins” folder at ~/Library/Application Support/audacity/Plug-Ins.” I did not have that folder, so I created it. All my other Nyquist plug-ins are shown as being in /Applications/Audacity.app/Contents/plug-ins. Looking at the file structure on my hard drive, they’re in /Applications/Audacity/plug-ins.

I placed the ChannelMixer.ny file in all three locations, closed & re-opened Audacity, even rebooted – and it still doesn’t come up as an option under Add/Remove Plug-Ins.

I feel like such a no0b.

The “~/” means your home directory.

Woo-hoo! That worked, thanks Steve. I had to add one step, downloading the file and MOVING it to that directory gave me an “alias” version of the file which would not enable. I had to specifically download the .ny file to my desktop first.

But it worked, so thanks 10~6.
