Installation

First of all, qaac is a 32bit Windows console application, and depends on Apple Application Support. Apple Application Support is not shipped as an independent package, but included in Apple products such as iTunes, QuickTime, or Safari. You need a version at least included in iTunes 10.5 or later. Usually, the latest one is recommended.

To install qaac, just extract the archive qaac_x.xx.zip, and put qaac.exe and other DLLs in x86 directory to where you like.

libsoxrate.dll in the archive is optional, and you can run qaac without it. However, some features of qaac such as resampling or lowpass filter require it. Therefore, I recommend you to copy it to the same place, too.

msvcr100.dll and msvcp100.dll are Visual Studio C++ 2010 runtime, and they are necessary to run qaac. It's likely that you already have them installed in your system. In such case, you won't need them. Alternatively, you can download Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package from MS site, and install it. You need vcredist_x86.exe for qaac and refalac. If you are running 64bit OS and want to use refalac64, vcredist_x64.exe is also needed.

If you want to directly import FLAC, WavPack, TAK, or other formats supported via libsndfile, you have to obtain the original distribution.

FLAC

Download flac-1.2.1-devel-win.zip from http://sourceforge.net/projects/flac/files/flac-win/flac-1.2.1-win/. Install libFLAC.dll in the archive into the same directory with qaac.exe.

WavPack

Download wavpackdll.zip from http://www.wavpack.com/downloads.html. Install wavpackdll.dll in the archive into the same directory with qaac.exe.

TAK

Download tak-x.x.x.zip from http://www.thbeck.de/Tak/Tak.html. Install tak_deco_lib.dll in the archive into the same directory with qaac.exe.

libsndfile

Download libsndfile-1.0.xx-w32-setup.exe from http://www.mega-nerd.com/libsndfile/. Run installer, and copy libsndfile-1.dll from Program Files (x86)/Mega-Nerd/libsndfile (default install directory for x64 environment, it may be different with your installation).
