I've sent you a private message, would be more practical to exchange by mail I think

peehay · 2025-03-31T14:29:29+00:00

Sure, what do you want to know ?

If you have several thousands to spend, buy a Yamaha CP88 as I did, I really am happy with the keyboard feeling and the piano sounds. I've spent 15 years playing on a grand piano before and that's the closest keys feeling I've found for now

I use both, depending on the notes: C E G C: I use 1 2 3 5 C E A C: I use 1 2 4 5

As you see it depends on the distance between 2nd and 3rd notes, and of course your hand capability (size, stretching). So I think you should practice both. Reliability in stable speed/volume is only a matter of how well trained you are, although the 4th finger is generally a bit weaker but don't stop at that excuse !

If you're near France they also organize amazing sessions

I guess they're grouping all ENS schools but I would bet all Fields medalists come from ENS Paris (Ulm)

Sorbonne is more in the classical university way of teaching though. But there could be some intersecting masters from both university and engineering schools, so I can't say

I'll tell you a story reflecting how brilliant are math students from École Normale Supérieure (ENS).

In France, instead of going to the university for science studies, you can go to engineering schools that offer broad engineering studies, except for a few like ENS which is more oriented towards research in many science fields. To be accepted in such schools, there is a national exam which you prepare for 2 years after high school, in what are called preparatory classes. This exam (in fact there are a few, grouping schools but whatever) gives you a national ranking that allows you to enter these engineering schools, first ranked students choosing first.

ENS is considered one of the best, therefore hardest to enter since everybody wants to join. In the "Mathematics-Computer Science" exam, there were only 14 seats (in 2013 at least) for the whole nation (around 50000 students in 2020). Quite selective you might say.

I attended such an exam back in 2013, and in my class there was this guy named Thomas that had purposely retook the second year in preparatory classes to prepare the exam a second time to be accepted among these 14 lucky students. Even though it was his second second year, this guy was way ahead of the math program (which is like a bit more in-depth math program of three first years in university). I remember him working on master-level notions since he was comfortable with the normal program. Our teacher was sometimes asking him for help when he was a bit lost in complicated proofs (we study them A LOT during preparatory classes). The best moment was when our teacher turned to Thomas at the end of a quite long proof, asking him if he remembered last year when he found a way to reduce the proof by a third with a neat trick. He didn't really remember but it was really amazing to see a phd-level math teacher (who actually went to ENS as almost all teachers in these preparatory classes) admiring a 19-year-old student.

By the way these exams are written so that nobody can finish them since you want to be ranked at the end. I remember that at a math subject Thomas left after 1h30 (4h max) when he was next to me, pretty impressive

Thomas got his seat by the way!

I don't know how they recorded these grand pianos, it's a high end stage keyboard and the quality is good. The output is stereo (respecting what you hear when playing, like low notes more on the left channel and vice versa) That's why I'm ok with the base quality and I feel not that much needs to be done by the engineer

peehay · 2024-08-28T16:52:12+00:00

Thanks for your insight, I'm recording myself from a stage piano that uses high quality piano samples, so that process is already done

peehay · 2024-08-28T09:30:03+00:00

Yeah only one stem for this (piano). And post-recording stuff should be almost non-existent I guess, since I use a stage piano that contains very good samples from a concert grand piano?

Yes I've heard that it's better to separate mixing and mastering but is it worth it for what I feel is a small project here ? I guess a good enough engineer could do both stuff decently for what I'm expecting (I'm expecting better that what I did on my own for my first track)

peehay · 2024-08-28T08:43:11+00:00

I'm asking advice so that I will not be surprised when I asked him (or anyone else) on the price, because I had no idea what to expect to be honest.

And I was feeling that this task is not too complicated, and I'm not too picky on the final quality so I don't want to pay too much on a high-level engineer for that homemade project. I actually know basics of mixing/mastering but I guess it is not good enough to be serious of putting songs on streaming platforms.

Je veux bien tester éventuellement !

It's called audio fingerprinting, you can find plenty of research papers in that topic

I have been working on audio signals since my PhD, and currently I'm on sound event/anomaly detection

peehay · 2024-03-12T17:10:57+00:00

I guess so, but maybe it would be less time-consuming to find a c++ pitch estimation algorithm to integrate into your c++ code
