AudioEffectChorus issue

[Angel]

I have configured the AudioEffectChorus as follows:

//buffer delay
short delayBuffer[AUDIO_BLOCK_SAMPLES*2];

//in the setup()
chorus1.begin(delayBuffer,AUDIO_BLOCK_SAMPLES*2,2) ;

then I change the voices parameter from 1 to 8 in real time and I don't hear the sound change anything.

Am I doing it the right way or am I missing something?

You want about 50ms delay, try 8*AUDIO_BLOCK_SAMPLES

With 2 blocks worth of delay that's about the same delay as speaker multipath in a standard room, so
its probably just going to acoustically enlarge the room slightly.

AudioEffect is a bit strange. The Chorus that I have seen usually have as parameters the number of voices, but also the type of LFO and the rate of the LFO
