Dear all, Yesterday you listened to Vina3.mp3 made from -gr.vina3 on BP3. Today I compared it with the same production on BP2.9.8 and I saw/heard a small difference. If you compare the sound recordings, they sound similar except that around t = 10 seconds the BP2 version includes a nasty sound ressembling the frictions that guitar players produce while performing. ;-) This would be impossible on a Sarasvati vina — and afficionados would be horrified! So, evidently we have an artifact which can be verified comparing the (enclosed) score files. I have not been able to understand why this happened. I am not too worried about it because the correct version is on BP3! Still, it requires some investigation into the way interpolation tables are constructed (the CsoundMaths.c file, pfff…) because it might be the trace of a bug. Csound experts are welcome to find the culprit! Some explanations in chapter 17 of https://bolprocessor.org/misc/docs/ will probably be helpful. I am also going to check all documented examples in -da.tryCsound. Bernard |
