I can't seem to get this plug-in to install on the latest version of Audacity. It's like it can't be seen. Copied file to the correct plug-ins folder but it doesn't appear anywhere.

Working on a Mac, which is pretty new to me, so maybe it's just something I am screwing up?

Any help would be appreciated.

What is the exact location that you copied it to?
On a Mac they need to be in:
~/Library/Application Support/audacity/Plug-Ins
where "~/" means your "home" directory.

If the plug-in is in the correct location, you should be able to see it listed in the plug-in manager (see: http://manual.audacityteam.org/man/mana ... yzers.html)

A note: When you run it, it doesn't say "Chris's Compressor!!!" It says "Compress dynamics". So it's easy to miss.

I run it at slightly different settings than factory. I change the first setting Compress ratio from default 0.5 to 0.77. It gives stiffer compression and matches almost exactly the local radio station.

Also there is a Bug Note. Make your show a little too long. Chris doesn't like running off the end of a performance, so it's best not to end the show too soon. I usually don't perform the last end edit, compress, and then cut off the extra.

These are three graphics of how it works. From top to bottom: original work, default and 0.77. Note the high peaks don't change all that much, but the low volume work gets a serious boost.

Any shortcomings will probably never be fixed because Chris reached "End of Life."

Hello,

I am new to Audacity and new to Chris's compressor too. I am looking for a way to properly normalize human voice so that the soft parts and loud parts appear to be more even. This compressor appears to do the job well. But I ran into a few problems.

1. 'Noise gate falloff' doesn't seem to work no matter how I set it. I've tried factor -2 and factor 10 and nothing seems to be different. Am I missing something?
2. Noise level at the beginning and end of the file seems to be greatly amplify after compression. Is there an easy way to fix this?

I am running Audacity 2.3.0 with Chris's compressor version 1.2.6 on a Windows 10 machine. Also, I am very new to sound processing. Is this compressor still the recommended way to even the volume? Is there an alternative that might work as well? I've tried the default Compressor and Limiter plug-ins but they don't seem to match the functionalities of Chris's compressor.

I just leave that at the default setting.

It can sometimes help to add a bit of "padding" at the start / end of the track before applying the effect, then trim off the padding after.
Generating a couple of seconds of silence at each end should be sufficient.

Chris's compressor can't cope with more than 1/100th of a second of true silence :
it truncates when there is > 0.01 of true flat-line silence.

Padding with typical (non-silent) audio copied from the track is a workaround.

I don't see that with "compress-b1.ny" (from the first post of this topic).

Sorry : I thought it was about Chris Capel's original plugin, (which has problems with true silence).

I had found that if you adjust the hardness (I think—it's been a while), it wouldn't affect the silences much.

And for clarification, Chris's compressor does not truncate silence. That's something completely separate from compression.

The old copy I have of Chris's compressor truncates accidentally if it encounters true-silence ...
