When you’re playing your music on your Mac, the sound is great.
But when you’re streaming it, things get a little muffled and grainy.
This is because your Mac is using a hardware DSP to compress audio.
That compression technique has been around for a long time and is sometimes referred to as a “compression engine.”
The problem is, the hardware DSC has its own compression algorithm, and if you turn it on, it can dramatically reduce your audio quality.
Here’s how to fix that issue.
If you’re interested in learning more about the differences between hardware and software DSPs, you might also want to check out this post on How to Enable Hardware DSP and Reduce Your Mac’s Sound Quality.
If your Mac isn’t using hardware DMS, you can disable the DSC.
You can do that by going to System Preferences > Sound > System DSP Settings and selecting “Disable Hardware DSS” from the dropdown.
If all else fails, you’ll have to make sure your audio settings are in the right place for the DSP.
In our previous tutorial, we disabled DTS for Mac, but if you’re on a Mac that uses a hardware-only DSP, you’re better off disabling that method as well.
If that doesn’t work, there’s a new tool available in OS X called SoundCheck that can help.
SoundCheck is a software-only software that analyzes your Mac for problems like the following: Low-frequency noise and distortion that doesn
