How to apply EQ or gain booster in the latest version?

[noho501]

Hi,

In older versions of HaishinKit, there was an AudioEffect interface that allowed applying custom effects (like EQ or gain booster) on audio buffers.
In the current version, this API seems to be removed.

What’s the recommended way in the latest HaishinKit to apply an EQ or gain booster effect?

Thanks a lot for your help! 🙏

I realized that there’s indeed no safe way to directly edit a raw AudioBuffer.

For something like EQ-level processing, it might be possible to implement it using AVAudioEngine.
As for gain control, you might be able to use AVAudioSession.setInputGain(_:).

I haven’t personally used it myself, so please take this just as a reference.
