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.

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.

Use DirectSound output only if you have a special reason for it, since the regular Wave Out is (usually) faster and more stable. It is recommended to use 100% buffer pre-fill with DirectSound output to avoid playback troubles. Buffer pre-fill can be set from the Player section.
