    // pan = (ans * 220L) >> 7.  That's the same as:
    // pan = (ans * 440L) >> 8.  And this way avoids a 7X four-byte shift-loop on AVR.
    // Identical math, except for the highest bit, which we don't care about anyway,
    // since we're returning the 'middle' 16 out of a 32-bit value anyway.
    pan *= 440L;
    return (pan>>8);
 
    // // return scale16by8(pan,220)<<1;
    // return ((inoise16_raw(x,y,z)+19052)*220)>>7;
    // return scale16by8(inoise16_raw(x,y,z)+19052,220)<<1;
