Apollo currently supports three different output devices: Wave Out, decode to .WAV and DirectSound. Use the radio buttons on the left to select the output device.

Wave Out is the regular Windows output system. If you have multiple sound cards installed, you can select from the combo box the one you want to use. Selecting "Wave Mapper" will use the default Wave Out device of the system. If you encounter problems with this output mode, switch to DirectSound, which is the recommended output mode for Windows 2000 and later.

With "Decode to .WAV" output you can perform a conversion from some other file format to standard Windows WAV. This way you can decode your MP3s file to WAVs for creating an audio CD, for instance. Or using a CD Reader input plug-in with Apollo this option makes it possible to extract tracks from an audio CD to .WAV files.

Allow continuous output binding

Enabling this will bind the output tracks with the chosen continuous playback mode. Each track, however, will be output to its own WAV file. This is handy for creating an audio CD with tracks mixed together with crossfades, for instance.

Create output directories for playlist

With this option, Apollo will create a directory to hold the WAV files for each playlist.

This is the recommended output mode for Windows 2000 and later. On older platforms you might be better off with the regular Wave Out. If you encounter problems with this output mode, switch to Wave Out.

Use hardware acceleration if possible

This option will allow the DirectSound drivers to use hardware mixing capabilities of the soundcard whenever it is possible. Hardware mixing usually means better sound quality, but with some drivers it simply means trouble.
