The Webernets has been running a bit slow lately, so I started looking at ways to speed things up. I stumbled on an article on WPMUDEV titled “How To Massively Reduce Your Images For A Faster WordPress Site“, and I thought I would put it to the test. I downloaded my entire images folder from my server, and here are the beginning stats.
As I am using a Mac, I downloaded the free app recommended in the article called ImageOptim (The article recommended Caesium as a free alternative for Windows users). I was impressed to read on the download page that “ImageOptim is lossless — it compresses image files without changing pixels.”
Opening the program shows a pretty familiar looking window.
63.9 MB saving is nothing to sneeze at, but I was interested to see if I could push it any further. In the settings, I found a “Quality” slider for Jpegs. By default, it is set to 100% hence the claim to lossless, So sliding it down to 80% will obviously reduce the quality and void the lossless claim, but is the trade off for file size justifiable?
With the Jpeg Quality Slider set to 80, I ran the program again on a copy of the original folder I made before the first optimization run. It took about 60 minutes this time, and here is the summary from the window footer
110.5 MB Saving on a 330.4 MB original file size is impressive. That’s 1/3! I went through a number of files to check the quality, and even though there is a slight difference if you look hard, for the most part the quality is good.

Below is a diagram on how to run your wiring between the devices.
Plug your USB Mic into a USB Slot, run an appropriate lead from the Line Out/Headphone Out of your computer into a stereo input channel on your mixer. If your mixer has only mono channels, use channel one for your left, and channel 2 for your right. Next, run wires from the Main Output of the mixer to your Line in/Mic In on your computer, and the physical part is done.
Next, open up Voicemeeter (If you don’t have Voicemeeter you can download it free at VB-Audio.com) and select your USB Mic as the device for channel 1. Make sure “A” is selected/highlighted and “B” is not selected.
All that is left is to open up the app you want to use (eg – Skype, Vidblaster, or some other Web Cam program) and select Voicemeeter’s Virtual Device (Output “B” in Voicemeeter) as the input source audio device.
Voicemeeter can be downloaded FREE HERE at vb-audio.com. Don’t forget to make a donation – the programmer deserves a little something for a program this good!
