Hey fellas. Came across this new video tutorial for this very thing. Right now I'm using the 30 band AU graphic eq to add a 'psycho-coustic' cut at around 3 Khz, as I find that a lot of program material sounds hot in this region.

Cool tweak. Thanks. Might be fun to see what happens when switching to a USB attached output device.

My pleasure, mate, and kudos to Dan Horn (dhorn92 on the Spotify forum) for the vid.

I missed this thread, but recently discovered AU Lab. Here's the download link:

John, have you compared Fabfilter Pro-Q in your setup vs. the AUNBandEQ plug-in built into AU Lab?  The Fabfilter UI wins hand's down, no contest, but that becomes less important once the filters are established, so I was curious as to whether you notice a difference in the actual acoustic presentation.

(I'm using AUNBandEQ for driver EQ, while an active analog line-level crossover handles the frequency splitting between the drivers in my active system.)

Have others run into other challenges?

My setup is starting to get more complicated, as I'm using an Aggregate Input Device that combines the (optical) Built-In Input (used when I connect my TV/Blu-Ray/etc.) with the Soundflower input (used when streaming music).  This is a new build still in-work, so I have yet to move on from iTunes, but eventually I'll give some of the other players (Audirvana+, Pure Music, Amarra, etc.) a shot and how well they integrate into this environment as well, complete with the various "hog mode", "integer mode", etc..

Thanks!

Hi Brian, I've not used AUNBandEQ, actually it's not there for me in AULab, I assume the available plugins are system-wide, but I'm not sure where it would/should come from.

I have run into an issue, which is that after some time AULab starts making ticking/clicking sounds, necessitating a restart. Still, it's much better than Pure Music playthrough mode or another app I tried (paid) called... er, Audio Plugin Player.

Thanks, John.

I had clicking on the Optical Audio Input until I set the "Hardware Rate Converter" to "automatic" in the Audio Devices section of Audio Midi Setup.

Interesting that you don't see the AUNBandEQ plug-in.  I know I didn't download it separately - it was included with the AU Lab package.  I downloaded AU Lab to my new (used) 2012 Mini less two weeks ago, but I've had it on my MBP for maybe a year?  In both cases, it was included.  I have AU Lab version 2.2.2.
