How To Speed Up a WordPress Web Site by Optimizing Images

Imageoptim LogoThe 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.

Original SizeAs 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.

ImageOptim WindowI dropped the whole folder in using the default settings and away it went. It took about 50 minutes, and here is the summary it displayed when finished.

file size savingsAnd this is the specs on the folder from the finder.

default optimized file size63.9 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?

ImageOptim PreferancesWith 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

Hard Optimize SettingsAnd here is how the Finder views the folder

Hard Optimized Finder Size110.5 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.

How to run a USB Mic through an External Audio Mixer

USB Mic through an External Audio Mixer – How To

USB Mic through an External Audio MixerI have been reading on forums lately how some people would like to be able to run their USB Mic through their external hardware mixing desks, and it is relatively easy to do.

Below is a diagram on how to run your wiring between the devices.

sound-flow-direction-diagram

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.

step 1Then, select your Line Out/Headphone Out jack as the device for Voicemeeters Main Output, “A1”.

Step 2Now it is time to select your Line In/Mic in as the device for Channel 2. Make sure that “A” is not selected, and “B” is selected.

Step 3All 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.

How to use a USB Mic AND Mixer together in Skype or Vidblaster

How to use a USB Mic AND Mixer together in Skype or Vidblaster

USB Mic AND MixerWeb cam software like Skype and Vidblaster only allow for one audio source, so if your mixer is coming into the computer via the line input, and your mic is coming in through USB, you are generally out of luck….until now.

I recently stumbled upon a free piece of software called Voicemeeter which makes it incredibly easy to solve this problem. It is basically a software mixer that will allow you to take various inputs as well as your system sound and mix them with a great deal of control into one “Virtual” sound device, which you can then select as your audio input device in your web cam program.

Voicemeeter Connection DiagramTo get started, Download your free copy of Voicemeeter HERE.During installation, you will get some dialogue boxes telling you it wants to install some drivers, this is completely normal.

voicemeeter-driver-installOnce you have installed it, you will need to restart your computer so the virtual drivers can register in your system. Once you have rebooted, open up Voicemeeter and you will see the mixing console.

voicemeeter Mixing ConsoleLooks cool doesn’t it! In short, you have two hardware inputs and one virtual input. The virtual input seems to be your system sound, so anything that tries to output through your computers speakers, like Winamp or Windows Media Player, can be fed into your mix here if you want it, if not, just mute this track by pressing the “M” button at the bottom next to its slider. To mix your Mic and Line In (Mixer) click where it says “1 Hardware Input” and select your USB Mic from the drop down list.

Select USB MicThe next step is to select your line in/mixer device in “2 Hardware Input”

Select Line InNow its time to tell Voicemeeter where your speakers are. Select them from the drop down menu that says “Hardware OUT”

select-speakersThe last step to making this all work is to open your Windows menu and select control panel. When this opens select the sound icon to open your computers sound preferences window. In the “Playback” section select “Voicemeeter Input” and then set it as the default device.

select-voicemeeter-in-soundNow you are all configured, you just need to do a small adjustment in Voicemeeter to stop feedback loops. The output of Voicemeeter has two channels, “Main Out” which will go to your speakers, and “Virtual Out” which is what will go into web cam software (Skype, Vidblaster etc….)

main out  virtual out
 In the “1 Hardware Input” channel, it is wise to de-select “A” as this will stop your mic from being played out aloud through your speakers. This will prevent feedback, but still allows your USB Mic to feed into your web cam program through the Virtual Out.

Channel SelectNow, all that’s left is to open your web cam program, Skype or Vidblaster etc, and select Voicemeeters output as your input device, and you can now use your USB Mic AND your external hardware mixer.

How To Use iPhone Android or Nokia Smart Phones as cameras in Vidblaster

Epoccam Icon

httpvh://youtu.be/Z5E-vEalubM

This video will show you step by step how to download and install software that will allow you to use your iPhone, Android Phone, or Nokia Smart Phone as a camera in Vidblaster.

**NOTE** – Your phone and computer need to be connected to the same wifi network

To get started, download the free Epoccam App from your devices app store and install it. Then, on your computer, browse to kinoni.com to download the free virtual device drivers. The software relies on Apple’s Bonjour networking technology, and if it isn’t already on your system, the installer will download and install it automatically for you. Don’t worry, it’s harmless!

Once everything is installed, open the app on your phone, then open Vidblaster, and add a new camera module and select “Kinoni Video Source” and you should be up and running.
