Audio volume level compression would raise all the soft sounds so they're almost as loud as the loud sounds. Good for Clasical music in the car. Pop music is already compressed out of the factory, to make it easy to listen to anywhere.

McIntosh had equipment in the 70s that included audio level compression, and it cost thousands of dollars. And they broke the audio spectrum into 3 bands, so as the bass, mids, and tebles got louder and softer, they would all be held steady, independently. If the volume of the entire frequency range is compressed as a single band, a bass beat might cause the mids and trebles to pump.

Should be easy to add a little DSP, multi band, digital signal processing in the Equalizer app to do the same thing, easily. Make those octacores work for a living.

Add a Compressor/Limiter

Amen. There are environments where 100 dB dynamic range is undesirable. E.g., in the car where you can't hear the soft passages; or at night where loud passages may wake up the baby...

Also, apparently, when your hearing isn't so good anymore -- for instance, post Led Zeppelin -- reduced dynamic range can be helpful, since the Pain Threshold becomes an issue.

On a tangent, a lesson I'd like to pass on to y'all: Just because your ears don't hurt doesn't mean the volume isn't up too loud.

Good work, thank you!

When I wave the mouse over an EQ slider, the mouse cursor changes to a big sloppy hand. A smaller, more precise mouse cursor would be more appropriate for the small slider controls. Maybe the extension could provide its own mouse cursor, perhaps a nice pointy arrow.

After playing with the EQ for a few seconds, I wanted to return the settings to Flat, but it wasn't a choice anywhere, and I got scared. It took me a while to find out that it's called Default. So, no problem.

I thought it would be helpful if there were a numerical readout for each slider, in dB's. It wouldn't have to be accurate, just something to make the sliders a little more quantifiable. Then I realized there are tick-marks every 5 dB's. That works 100% for me, don't need numerical readout anymore, so no problem.

In summary, I give the audio equalizer 5-stars-out-of-5.

Now I need better speakers, newer ears, and more World citizens demanding more progressive rock. And remember that just because your ears don't hurt doesn't mean the music's not too loud.
