可以使用AVAudioPlayer制作均衡器吗? [英] can I use AVAudioPlayer to make an equalizer player?

问题描述

我想为音乐播放器制作一个均衡器，它可以进行一些EQ设置，例如低音和高音，并且我想通过设置频率来改变音乐效果.
250Hz ， 1000Hz ， 16000Hz .

I want to make an equalizer for music player,which can do some EQ setting like bass and treble,and I want to change the music effect by setting the frequency.

但是我找不到AVAudioPlayer的任何API来设置频率.有人可以帮助我吗?我将非常感谢.

推荐答案

我认为AVAudioplayer不支持均衡器效果，因此您需要为所有音频单元应用频段，但是使用STKAudioPlayer可以轻松实现.请参考以下链接，它将为您提供帮助.

i think AVAudioplayer is not support for Equalizer Effect, for this you need to apply bands for all audio units but by using STKAudioPlayer u can achieve it easily. refer following link it will help you.
