I got this app to overcome the overprotective volume limits on my MacOS. SpeakerAmp does a good job of boosting those limits. A word of caution, there are limits you can apply to customize the app for your system. I recommend that you start with the lower settings and then turn them up if you need to. The app has the capability of causing pain and possibly blowing the voice coils on your headphones if you crank it all the way up. The free version is limited to a 10 band equalizer. I like the out-of-the-box equalizer presets on my music player better than the ones on this app. But those presets are just the starting point and I expected that would be the case from the get-go. The control panel is quite small on my monitor. I had to turn the resolution all the way up to make the sliders large enough to have a chance at adjusting them where I wanted. Expect to spend a bit of time getting it right if you are as picky as I am. After you get it adjusted you can save that setup as a preset and pretty much forget it. Or you can set the equalizer to flat and use the equalizer on your music player if you already have that one set the way you want. I always use only one equalizer in the audio pathway. Trying to use multiple equalizers is an easy way to make your music sound bad.The Pro version has a better equalizer and hopefully an easier to adjust control panel that you can leave on your desktop.But this thing does exactly what I wanted it to do.

SpeakerAmp adds equalizer and other effects to your iMac’s sound to improve your experience with different media. While the paid ‘pro’ version offers additional features pro audio users may enjoy, the free version is robust enough for any Mac user to have better audio. It has different presets you can select for different types of media to get a better experience. I use the “Movie” setting when watching shows and it makes everything so much better with richer sound that just seems to fit. There are a number of pre-baked settings like ‘spoken word’ that can really help with certain types of media. At one point, I believe it had a setting to cut off pops and hisses but I cannot find it anymore. Maybe it was a pro feature. I did not give it five stars because you, the user have to activate the settings rather than them be selected automatically based on your media, and because when switching between your built in speakers and headphones - without the app just plugging in headphones is enough to switch. With the current version of the app, you need to select headphones - and in the case of Safari, quit and restart the app to use headphones. Still, the difference is night and day between the flat Mac sound and what the app gives you. Thanks to the developer for a great app!

I'm so glad that I found this app because it's been so useful adjusting the audio levels of my bluetooh speakers that I connect to my M1 and M2 Macbook Pros. Essentially instead of purchasing a desktop speaker system, I've been using my Sony SRSXB41, Lenovo, and JBL speakers with my laptop. Since apple for some reason doesn't have their own built in equalizer, this app has been awesome in allowing me to adjust the EQ for basically any audio device. Yeah it's really weird how those speaker manufacturers develop the speaker apps for an iphone or ipad only, and not the actual desktop/laptop computers. Well anyway, try this app out and see what you think. I bet you'll be like me an end up purchasing the pro version after the introductory trial is over. Don't wait, try this app now.

This product being advertised as an all-purpose system-wide volume adjuster is unfit, as it has great difficulty keeping up with bluetooth devices and sound synchronization. If you are using this program to simply edit and equalize sound then I can see how it would be properly lauded; however, using it to try to simply boost volume on a bluetooth device has proven useless.The program is unable to interact with bluetooth volume controls, causing conflict where the volume shown in the booster program is not kept synchronized with system volume. This means that pushing the volume up and down buttons on the MacBook actually functions differently than pressing the volume up and down buttons on the bluetooth device that is connected. This makes the program a complete pain to keep up with, as you have to constantly enter the volume booster to manually synchronize the two layers so that they don't end up in some weird configuration that is an undetermined combination of both levels.In addition, the program frequently loses its place when using the bluetooth play/pause function on my headset, where it will simply fail to play any sound through the volume booster and force the user to enter System Preferences and select their sound device again and again to force it to play.Overall, this program is clearly not tested or designed to operate in conjunction with bluetooth audio devices and fails miserably at that task.
