The amount of developing time for a reverb algorithm is very much depended on the goals and target for that particular algorithm. If you want to make a high-end classic and start from scratch then it takes way more time than contract work.
VSS series from TC Electronic took 8 engineers almost 10 years to finish. Bricasti (Casey) use at least 4-5+ years for a single algorithm. Lexicon (David Griesinger) worked 3 years on the HD algorithm. And so on. The above is obviously flagship products and not contract work. And none of them use FDN in the traditional sense. -----Original Message----- From: music-dsp-boun...@music.columbia.edu [mailto:music-dsp-boun...@music.columbia.edu] On Behalf Of gm Sent: 21. maj 2020 23:04 To: music-dsp@music.columbia.edu Subject: [music-dsp] the time it takes to design a reverberator and related I need some possibly quotable real world opinions and experiences on how long stuff can take to design or develop, especially takeing Hofstadter's Law into account For instance reverberators, hard to estimate, and I dont recall all the times I spent exactly I tried so many things on different occasions so long ago, improved things, disimproved them but my estimate is that it takes many months experience (at least) and experimenting to come to good and really good results. Especially if you start with FDNs first and waste a long time on them... If you have experience and start from scratch it takes days or weeks to refine your design. You may however have at some point developed prototypes that you can reuse and modify and do not change too much any more. Two years ago or so I posted a kind of non-paper here on "magic numbers in reverb design" where I claimed having found a "perfect" ratio for allpass delay stage lengths. I could never decide if its kind of nonsense or not since the method gives quite good results, but I think I used other numbers afterwards myself IIRC. I am not even sure at the moment... Does anybody recall that paper and did anybody ever try and remember the results? Did it speed developement up for you? Did it make any sense to you at all (its written in a weird way)? Would you call a good reverb algorithm a piece of art? Since the process can take so eratically long, and since you can go back and forth many times, what do you think a reasonable time estimate would be? How much time would you charge for that reverb, reasonably? How and when do you decide it's finished and that you don't change parameters any more? How many times and for how long did you try to make "the most efficient reverberator you can get away with"? Did you ever succeed in that quest? Do you think there is something like a "most reasonable" reverb design? _______________________________________________ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp _______________________________________________ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
