File Player

Use the File Player to play .wav or .mp3 files and to record the computer audio if you require. For most people, there will never be a need to change the Output Mode. If you are keen to use an ASIO driver, you can choose this setting here. Also, if you experience any problems with your output drivers or hear some disruption in your audio, you may find that changing the output mode will help.

WaveOut - the default output used by Windows to connect to your sound card
Wasapi - A newer output by Microsoft, which was intended to be the next big thing but never became as popular as expected
Direct - Direct Sound Out, an alternative API to WaveOut
ASIO - a powerful, low-latency output, popular with sound engineers and audio software programmers. This is not included within Windows and requires an additional driver. The most common ASIO driver is ASIO4ALL and can be downloaded for free at asio4all.org

The audio buffer size can be adjusted for WaveOut and DirectSoundOut within the Harmonic Equalizer application in "File Audio..." under "Settings". The ASIO buffer size can be set within the driver (e.g. ASIO4ALL).
