iMac Sound Quality Driver v1.0

Before installing this driver, please check that a
Microphone playback is switched off.

(If after tapping computer on the top, the tap is 
immediately heard back from the speakers - then it is 
a sure sign that the microphone is not muted and may
create an unpleasant resonance in the sound.)

To switch the microphone off:

   1. Right click on the speaker icon in the system tray
   
   2. Select: Recording devices
   
   3. Right click on the Microphone, select Properties. 
   
   4. On the Listen tab, "Listen to this device" should 
      be unchecked.
      
   5. On "Levels" tab, the blue speaker button should 
      display a small red crossed circle, signifying that 
      it is muted.


Note, this driver was made using measurements taken from 
aluminium 24" iMac. This driver will not properly adjust
the sound on MacBooks, and sound adjustments for other 
iMac models might not be optimal. 

This driver was only tested on Windows 7 and supposedly
should work on Windows Vista. Both 32-bit and 64-bit
versions should be supported.

The side effect of installing this driver is that:

   All DRM audio will be disabled, such as music from 
   Microsoft URGE store, and Blu-ray discs. 
   
   However Music from iTunes store will still work.

   Standard RealTek audio effects will not be available. 
   Settings such as environment, reverberation and 
   equalization will disappear.

   This fix might be incompatible with 3rd party sound 
   changing effects software, such as pitch shifting, 
   voice morphing, etc.

The author disclaims all warranties about this software. 
If for whatever reason the computer is blocked, please 
boot up into a Windows safe mode, run this utility again 
to deinstall the driver.

Technical information:

    This program will install an LFX system audio effect 
    with a long chain of equalization and modify the 
    registry to replace the standard RealTek and Microsoft 
    driver effects.

    A file MacFixAPOLFX.dll will be copied to the Windows 
    system folder and registered as an audio object.

    A technology which is used to create this driver is
    described on this Microsoft's page:
