AKEqualizerFilter的带宽参数如何影响Q-factor?

问题描述 投票:1回答:1

我正在使用AudioKit的AKEqualizerFilter在我的应用程序中添加一些均衡器,我只是想确保我理解带宽参数是如何影响Q因子的。根据我的理解,用中心频率除以带宽就可以得到Q-factor。所以如果中心频率是50,带宽是50,那么Q因子就是1,如果带宽是25,那么Q因子就是2,我的理解是否正确?

这是一个好问题! 我认为最好是在这里检查实现 ( https:/github.comAudioKitAudioKitblobmasterAudioKitCommonNodesEffectsFiltersEqualizer%20FilterAKEqualizerFilter.swift。 )

/// A 2nd order tunable equalization filter that provides a peak/notch filter
/// for building parametric/graphic equalizers. With gain above 1, there will be
/// a peak at the center frequency with a width dependent on bandwidth. If gain
/// is less than 1, a notch is formed around the center frequency.
