question about svf


    Aug 18 2009 | 6:11 pm
    Hi,
    The value of the svf~ parameters is only sampled once per signal vector.
    What does that mean?Can this cause sound quality issues?
    Thanks

      Short answer: if your doing something that requires timing resolution below your vector size then this object is inadequate. For instance if you need to change the q exactly every 801 samples use a different object. Otherwise don't worry about it.

      like what? one of the filters which take input every sample? biquad? or FIR?

      This only applies when you connect a signal to the inputs that control frequency and slope. If you would connect a line~ that ramps from 600 to 800 (hz), instead of a continuous change, the frequency would move in discrete steps, one step sampled every signal vector size. In SuperCollider this is called control rate, as opposed to audio rate.
