QuickTime volume control in the Finder Desktop
The following was submitted to me via email, and it's an interesting tidbit. I'm sure everyone knows that you can play MP3's in the Finder's column view mode, but did you know that the volume was keyboard controllable and has a "super loud" mode? Here's the email...
I was listening to an MP3 in column preview mode and wanted to select it and some others using the keyboard. So I hit the shift and up arrow keys and the volume started to change! Playing around with it, the up and down arrows adjust the volume, but the shift and up arrow can make the volume even louder (think Spinal Tap's "11"). It appears that the quality starts to suffer using the shift key. Using the up or down arrow alone will return things to the normal scale.
I knew that the arrow keys would control the volume, but I had never thought to try a shifted arrow key. Since this is QuickTime at work, the same trick should work for movies or any other files that QuickTime controls.

Use the control key
Authored by: Fraki on Jun 07, '02 10:36:03AM

I couldn't get the same effect just using the arrow keys with or without shift - but instead, using the control key with the up and down arrow keys will change the volume, and shift-control-up arrow will make it go quite loud. (In the meantime, I also discovered that command-up arrow will take you up a directory, and command-down arrow will take you 'forward' one directory if applicable.)

Shift-click on the sound icon

To see the volume level with the extra-loud level added in. This is an old trick with Quicktime that dates back to the original versions of the early 90s.

Aha! It must be preamping it!

The only thing I can figure for this, is if the quality starts to suffer when you turn it up, and you can make it very loud, then QT must have a preamplifier that it's not telling us about, and the normal volume control affects the "power amp" equivalent! Meaning that it should be possible to crank the preamp VERY high and keep the power amp low so your eardrums don't burst, and then play something loud - and POOF! instant distortion! Of course it will probably sound utterly horrid because it's not tube or transistor amplification, but software, which will probably sound like digital audio clipping (i.e., wraparound, also known as "*terrible* sounding"). QT is full of all kinds of awesome features like this! =)

Speaking of shift
Authored by: percy on Jun 07, '02 07:54:13PM

Speaking of shift; something I had not noticed before is, that if you raise or lower your volume with the volume buttons, while holding down shift, no alert will sound. Anyone know how to make that the default mode? (Or point me to the hint describing this, if I have missed it.)

That's a hint! I hate it when I'm listening to something and have to adjust sound level: bing... bing... bing... I now know how to avoid it, thanks to you! Kudos!

I think that's worthy of posting on its own...with full credit to the author, of course!

QuickTime volume control in the Finder
Authored by: ice_cold_irony on Sep 11, '07 11:14:19AM

WOAH! that is sweet, it definitely is a pre-amp because if you use<at least on a macbook> the volume down key after the 3rd bar the volume you can really notice that it doesn't scale down linearly.
My question is, how do you apply this pre-amp across the board? Itunes especially could use this, as the macbook speakers are really limited and not even loud enough in a relatively quiet room.
The distortion isn't even that bad surprisingly...the high and low ends get a bit fuzzy but definitely tolerable. Also, what is with apple constantly crippling their products?

In Sound prefs uncheck the box "Play feedback when volume is changed." With this unchecked, holding the shift key brings back the beeps as you change the volume.
