Apple technology has always been notable for its simplicity and ease of working with multimedia. The revolution of the iPod player is not only in its compactness, but also in the quality of the reproduced sound.

The ergonomics and minimal thickness of the iPad or MacBook Air did not prevent the company from installing decent speakers and taking care of good sound on mobile devices. Decent mobile sound is a nightmare for audiophiles, but we will not consider ourselves as music lovers in this category, and in today’s instructions we’ll just do our best to squeeze the maximum out of the MacBook speakers.

The options for achieving good sound are somewhat demanding to understand what you are doing. By “good sound” I mean one that is significantly louder than the maximum allowed value of Apple-limited sound that has volume and a balanced frequency picture.

Improving the Sound of macOS using Equlization

In order to play over the sound of your MacBook, you can use the free alternative. The only “but” – you will need two applications at once and minimal skills to work with sound plug-ins. If you are ready – feel free to fight!

Attention! I’m not responsible for any hardware and software damage to your devices. Abuse of volume can harm the dynamics of your laptop. Please be attention with settings!

We will need the Soundflower application that emulates an additional sound card in the MacBook and a virtual distributor of audio ports — Apple’s AU Lab application:

  • Download Soundflower;
  • Install and reboot the computer;
  • Download Apple’s AU Lab;
  • Go to Settings -> Sound. For Output, choose Soundflower;
  • Open the AU Lab application and set the settings as follows: as the input signal (Audio Input Device), select the installed Soundflower and as the output signal (Audio Output Device) select the Built-in output;
  • Click Create and see a window with two bands – the mixer of our audio signals. Raise the volume sliders to the maximum;
  • Now our task is to enhance the sound. We will use the plug-ins built into the system (subject to Garageband installed). For sophisticated users working with sound processing, you can use any “best plug-ins.” On the Output 1 track, in the Effects field, select the AUNBandEQ plugin;
  • In the plug-in window that opens, the Global Gain slider is raised to 24 decibels. If the received volume is not enough – we catch another plug-in in the appeared free field of effects and amplify it;
  • Attention!!! Do not overdrive it! Overdriv of sound, wheezing and plunging suggests that the volume level is too high for speakers installed in a MacBook;
  • Now you need to put the equalizer plugin and build it the way your ears want. Choose AUGraphicEQ;
  • Turn on your favorite song, switch the equalizer to 10 bands and move the sliders, adjusting a sufficient number of low, mid and high frequencies;
  • After finishing the settings in the AULab application, select File -> Save and specify the directory to save all the settings of your profile.


In the future, when you open the AU Lab, you can use it. There was a long way, but we did it! My Congrats!
