Hi Steve,
I've been trying to figure out how to do some simple distortion / clipping in Chuck. I'm not sure I fully understand the GenX objects. Is this the best way to do it?
Can you show your patch? Clipping involves waveshaping, so you should know the expression of the clipping function (i.e. x-x^3/3) and substitute x with audio samples. Possibly, with GenX functions you could multiply your samples at time t with your GenX sample at time t but you should hardclip your output so it does not exceed 1. Otherwise you get unexpected behaviour as you say: <quote>
I find my audio output significantly degrades (i.e., sound pops, goes silent, or makes strange unpleasant noises) when I exceed this limit, so I always have to fight to keep it within the correct range. <quote>
You could try this. Don't know if it's the best way, but it's some way... fun float softclip( float x ) { if( x > 1. ) return 2./3.; if( x < -1. ) return -2./3.; return x-x*x*x/3.; } fun float hardclip( float x ) { if( x < -1. ) return -1.; if( x > 1. ) return 1.; return x; } adc => Impulse imp => Gain vol => dac; 10 => adc.gain; // pre amplifying input signal, Change accordingly 1./adc.gain() => vol.gain; // keep same headroom. you can skip this. while( now < later ) { hardclip( adc.last() ) => imp.next; // softclip( adc.last() ) => imp.next 1::samp => now; } Plug-in your guitar, now! There may be some errors, as I have not execute the patch. Alternatively, you may use atan(x) for waveshaping instead of x-x^3/3. hope it helps, eduard
