SETUP WIZARD

DirectSound Driver Setup

In the DirectSound streaming buffer section you'll see a slider that sets the audio buffer length.

A larger buffer setting means more stable performance (without underruns). However, a larger buffer also means that there will be a slight delay between playing notes (important if you have a MIDI/USB keyboard connected), tweaking knobs and pushing sliders and the response of FL Studio. The delay will be the same as the buffer size.

The ability to reduce the buffer size without buffer underruns (clicks and pops in the audio) depends on your CPU speed and sound card. It's recommended to leave the default settings and try the demo songs. You may then need to come back to the audio settings F10 and fine-tune the setting (buffer as small as possible without any underruns, 20-40 ms is typical with a good card). Note that the best buffer size may vary from project to project, depending on the CPU usage of the song.

For more information on the rest of the settings in that section go to the Audio Settings page.
