Distortion, clicks, and pops can destroy an otherwise good recording session, and these problems 99% of the time are manufactured by something simple and easily avoidable. So here are a few quick things to check if you ever run into these situations.

Update Firmware, Software, and Drivers

The first thing that you must do is make sure your system has been completely updated. Lets say you just updated your OS to OSX Yosemite and you installed the drivers from the disc that came with your audio interface. You should always go to the website of the software you are installing and check for the most current software and drivers. With quick things move in the computer world, it is not always possible to possess the latest driver on the installation disc that comes with your software, even if you just purchased it.

It is also wise to make sure any audio applications, software synths, and plugins you own are up to date as well. Always go check the manufacturer’s website and update according to what they say in their instructions.

Buffer Settings

The next to check after you have updated your software would be your buffer settings. One of the simplest fixes for these types of problems can be changing your buffer settings. Understanding why you might possibly need to change the buffer setting can be a bit more difficult to understand and will be discussed separately.

Fixes

For the simplest answer: If you are getting distortion, pops or clicks in your recording raise the buffer setting in your audio application. In Logic, click on Preferences > Audio. On the Core Audio tab you will see “I/O Buffer Size.” Regardless of what the buffer size is set to, move it to the next highest number. For example, if your buffer size is currently set to 32, change it to 64. If it is set to 64, then move it up to 128, etc. In GarageBand, it is a bit easier: Click on GarageBand & Preferences. Click on the Audio/Midi icon and you will see the following screen:

Change to “Maximum number of simultaneous tracks/Large buffer size.”

Pretty much every other audio application will have very similar settings. If you are not sure where to these settings then contact the software manufacturer or look it up on Google or YouTube. If switching the buffer doesn’t fix the problem, the next step is taking a look at other USB or FireWire devices you may have plugged into your setup.

Other USB or Firewire Devices

Quite often other FireWire or USB devices connected to your computer can cause problems if your audio interface is FireWire or USB. Conflicts with other audio interfaces, cameras, etc can usually cause the biggest problems, but external hard drives can also cause problems as well.

Solution

If you are having problems with distortion, pops, and clicks and you have other devices connected to your computer, try the following:

1. Turn off your computer and unplug all USB and FireWire devices except for your main audio interface.


2. After you turn your computer back on, play something from iTunes and make sure the audio you are hearing sounds clear.


3. If you have an external USB or FireWire device, connect it to your computer and try running your session again.


4. If you are still having problems it might be time to bite the bullet and reach out to the manufacturer’s tech support.

It is best to keep all other devices disconnected from the computer while working on audio. The new Mac’s on the market are amazing and extremely powerful. If your desire is to record professional quality audio then you might not be able to connect every USB and FireWire device that you own because there is a limit to what you can do with your computer and DAW. If that is not your desire, connect all your devices back up and just keep doing what you are doing.
