Effects And Radio Windows

Effects Window
All effects are applied to audio as it transmitted out of Airfoil. Use Effects to adjust audio output through your AirPort Express units.
Volume - Adjust the volume of the audio. This slider goes up to 200% for "double gain", which may cause audible distortion.
Balance - Adjust the speaker balance from left to right. Defaults to Center.
Equalizer - Adjusts audio using the high-quality 10-band EQ, with Custom settings or many included presets.

Radio Window
The radio window in Airfoil allows for adjustment of USB radio sources, which can be a Griffin RadioShark or D-Link DSB-R100 radio.

Main Controls
Tuning Slider - Adjust the frequency to which the radio is tuned
AM/FM Toggle - Adjust the band on which the radio is receiving.
