But, how about watching HD video on Youtube? Yup, we don’t have EQ set for that, also for Quicktime, and practically anything, …
Of course we could buy the EQ system for that,
But, there’s a free workaround for that
Here we go:
Install AU Lab, previously is part of XCode, now can be downloaded at https://developer.apple.com/downloads/index.action#
Install SoundFlower from https://code.google.com/p/soundflower/ got 1.6.6b version, restart the mac
Alt-clickthe speaker symbol and choose soundflower as output device
start Sound Flower
choose audio setup right clik soundflower and click “use this device assound output”
richt click Soundflower again, this time choose ‘configure speaker’
choose multichannel, choose stereo, click the round-rectangle area, done
Start AU Lab, all the way around till got this one
doubleclick the output1, make sure it use soundflower
then click ’show device preferences’, set to soundflower
done
now you can add effect like EQualizer, timeshift, echo, whatever and it’ll affect general sound of OS X
