Any single or multi-channel soundcard with one of the following drivers is supported:

• DirectSound (WDM) driver
• Core Audio (WASAPI) driver
• Steinberg Audio Stream Input/Output (ASIO) driver (recommended)

For best quality we recommend to use a professional audio soundcard which supports full 32-bit or 24-bit processing. Note that you can use any number of soundcards in your system. However, you should try to avoid mixing the type of driver between multiple soundcards (i.e. if available use only ASIO drivers, then use only WASAPI drivers and finally use only WDM drivers).

ProppFrexx ONAIR requires the Microsoft .NET Full Framework in version 4.0 or above. The latest .NET Framework will normally be installed with your Windows Operating System. However, you can obtain the .NET Framework from the Microsoft website: here.
It is recommended to install the latest service pack for your .NET framework (we recommend using the latest .NET Framework 4.5)!

Furthermore the Microsoft Windows Media Audio Codec resp. the Microsoft Windows Media Foundation is required if you intend to playback WMA or MP3 files. The Windows Media Audio Codec will normally be installed with your Windows Operating System, however, you might also install the latest Windows Media Player: here.

For certain functionalities it is also recommended to install the latest DirectX version, which can be obtained here: here.

There should normally be no need to install any of the above mentioned 3rd party software, as this typically already comes installed with your operating system.

ProppFrexx might leverage the QuickTime runtime for AAC support, which can be downloaded here: here.
(Note: installing iTunes will also install the latest QuickTime version, however iTunes is not required to be installed for AAC support)

For streaming AAC+ content (e.g. to a SHOUTcast server) ProppFrexx will use the Winamp media player libraries. So make sure to install Winamp if you plan to stream in the AAC+ format. Winamp can be downloaded here: here.
