can I use AVAudioPlayer to make an equalizer playe

问题:

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.
250Hz, 1000Hz, 16000Hz.

(void)setEQ:(@"250Hz");
(void)setEQ:(@"1000Hz z");
(void)setEQ:(@"16000Hz");

But I can not find any API of AVAudioPlayer to set frequency.Can anyone help me? I will be very grateful.

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.
