//------------------------------------------------------------------------------// name: chorus.ck// desc: basic demo of the Chorus UGen//// The Chorus UGen adds a chorus effect to a signal. Chorus refers to an audio// effect in which multiple sounds occur close together in time, and with// similar pitch. The slight deviations in pitch and time are generally small// enough such that the signals are not perceived as being out-of-tune. The// effect is often described as adding "shimmer", "richness", or "complexity"// to the timbre. When implemented digitally, the chorus effect is acheived by// taking a source signal, and mixing it with delayed copies of itself. The// pitch of these copies is usually modulated using another signal like an LFO.// In ChucK, you can adjust the depth and frequency of this modulation of pitch,// as well as the amount of delay and how much of the chorus effect is present// in the mix.//// author: Alex Han// date: Spring 2023//------------------------------------------------------------------------------ // set up signal chainSinOsc s[4]; Chorus chor[4];// chorus often "shines" best with polyphonic textures![62, 65, 69, 72] @=> int notes[]; // connectfor( int i; i < s.size(); i++ ){    // patch each voice    s[i] => chor[i] => dac;     // sine wave as source signal    s[i].gain( .2 );    s[i].freq( Std.mtof(notes[i]) );     // initializing a light chorus effect    // (try tweaking these values!)    chor[i].baseDelay( 10::ms );    chor[i].modDepth( .4 );    chor[i].modFreq( 1 );    chor[i].mix( .2 );} // time loopwhile( true ){    // nothing to do here except advance time    1::second => now;}
