Use it to compensate for existing deficiencies in audio. AudioEffectEQs are useful on the Master bus to completely master a mix and give it more character. They are also useful when a game is run on a mobile device, to adjust the mix to that kind of speakers (it can be added but disabled when headphones are plugged). </description> <tutorials> <link title="Audio buses">$DOCS_URL/tutorials/audio/audio_buses.html</link> </tutorials> <methods> <method name="get_band_count" qualifiers="const"> <return type="int" /> <description> Returns the number of bands of the equalizer. </description> </method> <method name="get_band_gain_db" qualifiers="const"> <return type="float" /> <param index="0" name="band_idx" type="int" /> <description> Returns the band's gain at the specified index, in dB. </description> </method> <method name="set_band_gain_db"> <return type="void" /> <param index="0" name="band_idx" type="int" /> <param index="1" name="volume_db" type="float" /> <description> Sets band's gain at the specified index, in dB. </description> </method> </methods> </class>
