AudioEffectEQ
继承： AudioEffect < Resource < RefCounted < Object
派生： AudioEffectEQ10, AudioEffectEQ21, AudioEffectEQ6
Base class for audio equalizers. Gives you control over frequencies.
Use it to create a custom equalizer if AudioEffectEQ6, AudioEffectEQ10 or AudioEffectEQ21 don't fit your needs.
描述
AudioEffectEQ gives you control over frequencies. 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).
