Well as my very lovely lady is away, and I seem to have irked my hamstring somehow AND the weather here is utter rubbish at the moment I thought I would crack on with some improvements to my Sound Engine.<\/p>\n
Last few days have been spent faffing with the Vibrato effect, this effect takes two parameters, one sets the frequency and the other the amplitude of a pitch distortion of a playing sound.\u00c2\u00a0 It always gives me a headache to code, and as my OCD tends to want perfection that irks me further.\u00c2\u00a0 The amplitude is based on 8ths of a semitone, of course as these are calculated by a non-linear expression it requires some look up action.. but then if you are coming off the end of a slide, there is a good chance that the current playback period may not actually exist in your lookup table.. so I engineered a less than accurate, but hopefully good enough work around.<\/p>\n
So I compute a percentage of the current period which is approximetly the same size as an 8th of a semitone between the current note and it’s neighbour, so whilst not 100% accurate, it works irrespective of the actual playback period and gives similar audiable effects.<\/p>\n
Overall I am quite pleased with my solution, that combined with the other effects I have added support for and the improved timing code so that non 50Hz timing based modules play correctly make quite a lot of modules that sounded a bit iffy now sound bob-on..<\/p>\n
Of course this has meant I have had to rethink a lot of previous ideas, had new ideas and subsequently need to re-write a fair chunk of the code before I progress further.. or I will claw my own eyes out, but its all going nicely and I have my most hated effect completed, so the rest should be easy now… should be… \ud83d\ude00<\/p>\n
