Mario Martinez Posted December 10, 2018 Author Share Posted December 10, 2018 Here is something you might find interesting... It is a paper on "Timbre Solfege" written by Tomasz Letowski from the U.S. Army Research Laboratory and Andrzej Miskiewicz from the Fryderyk Chopin University of Music. The paper discusses the foundations of "Timbre Solfege" (a course in perceptual analysis of sound) and presents the current version of the course program from a perspective of over three decades of its existence in the sound engineering curriculum. The interesting thing about this paper is realizing that the timbre we hear in every recording is not a direct product of the timbre of the physical instruments, but a product of the psychoacoustic abilities of the engineer that made that particular recording. No matter how far technology goes (better mics, better preamps, better converters) there will always be a "black hole" on the recording chain that will prevent us from capturing the timbre of instruments "as is" That "black hole" is located on the recording chain between the instruments and the mics and, according to this paper, the only instrument we have to restore its effects is the psychoacoustic abilities of the recording engineer himself. But how can we be sure that work has been done properly? There is no objective way to check that this work has been done properly. The only thing we can do (like the engineer did) is use our psychoacoustic ability to subjectly determine if the timbre sounds right to us, but in our case we have not even had the chance to hear the physical instrument. Our research has to do with all this. The purpose of our work is to develop a methodology that will ensure we get the right timbre on the recording without the use of subjective evaluation.

Mario Martinez Posted December 14, 2018 Author Share Posted December 14, 2018 Here is some info that might be helpful in the evaluation of the different calibrations. The purpose of our methodology is not to make each album sound as "good" as possible. If we wanted to do that we would not use one single calibration for all our albums. Instead we would master each album separately to obtain whichever sound we liked best. For example, say we are recording a small piano that has very little bass, we could compensate the recording to make it sound bigger. That is actually the standard procedure in any regular recording project. The purpose of our methodology is to make each instrument sound as "truthful" as possible. That means portraying the timbre of each instrument "as is" with all its good and bad qualities. No instrument is perfect in every way, some have a glorious bass, others have beautiful treble, other rich mids, some sustain wonderfully; choosing an instrument is always a compromise. When we developed calibration 2.0 we only had one piano to work with. We tried to be as objective as possible on the developing of our calibration but with only one instrument to run test with it was easy to be bias by the particularities of the instrument. We were not aware of this when we presented 2.0. The recorded sound was so good we were convinced we had gotten it right. But running further tests made us realize that we could have unintentionally tweak the calibration in favor of that particular piano. That is when we decided to get the new piano. We thought having two completely different instruments placed at two different spots on the stage would help us stay objective. Running 2.0 over this new piano was an eye opener for us. It did not just confirm our suspicions but it also gave us immediate clues as to what was going on. But fixing it proved much harder than hearing it. We spend a long time trying to fix what we knew was there but we did not manage to get it right. Every time we thought we had something we would test it against the old piano just to find out that we were being fooled again. At some point (probably drawn by desperation) we wondered away from our initial philosophy and decided to use two different calibrations (2.0 for the old piano and 3.0 for the new piano) but that would have been wrong. It would have been just like mastering each album in a different way. Back then we convinced ourselves that this was the only way; we even came up with a good excuse that justified the use of these two different calibrations (that excused is explained on the 3.0 thread) But some how (and with the help of some of you) we came back to our senses, we decided we would try it again, and this time we did manage to get something that worked on both pianos.

kravi4ka Posted December 15, 2018 Share Posted December 15, 2018 I would like to apologize for my review being late, I have a technical problem that requires complete computer change... It will take a few days but I keep my promises. Thanks again! Link to comment
bruny Posted December 15, 2018 Share Posted December 15, 2018 I’d love to give your pieces a listen also interested in Cabrera plays Debussy. Many thanks Sir Link to comment
Mario Martinez Posted December 16, 2018 Author Share Posted December 16, 2018 Here are some sketches that may be useful as a reference on your evaluation. The blue area represents the stage. The person in red represents the mics. The following sketch represents instrument placement for the old albums : - Debussy Preludes. Book 1. - Chopin Polish Songs - Iberia - Songs of Paolo Tosti - Cabrera plays Debussy - Conversations The black piano on the sketch represents the old piano: a smaller size piano placed further back on the stage. The following sketch represents instrument placement for the new albums: - An evening with Riera - From Russia with love - Mozart - Beethoven wind quintets - Goldberg Variations - Ad Astra The brown piano represents the new piano: a bigger size piano placed up front on the stage. And these are the sketches for the classical guitar, drums, flamenco and strings: All these recordings have been done using the exact same setup: same hall configuration, same mic arrangement and position, same recording chain, same calibration. The only thing that changes from one recording to another is the instruments themselves and their position on the stage.

Bob Stern Posted December 16, 2018 Share Posted December 16, 2018 Mario: I would appreciate "Stories" as the free album. Muchísima gracias! p.s. 2 previous albums that I recommend to others are Debussy by Cabrera and Albéniz by Grané.

kschac Posted December 16, 2018 Share Posted December 16, 2018 Mario: I would love to get a code as well. I have several of your older releases (they sound amazing to begin with) and will be interested in comparing the new sound. For another album, I would like From Russia With Love -- big fan of piano transcriptions! Thanks Link to comment
Mario Martinez Posted December 17, 2018 Author Share Posted December 17, 2018 If the calibration is right, what you see on the recordings should match what you see on the sketches. In other words, all the instruments on all these recordings should be rendered by your systems in a way that their relative position to one another matches the position of the physical instruments on the stage. Why is this important? The "black hole" we were talking about before is the one responsible for the deformation of the spectrum of all recorded material. That deformation does not just affect timbre, it also affects depth, presence, balance, position, etc... If you were to record several instruments (like we did) using a fixed two mic setup with no mixing, you would definitively be able to perceive the effects of this "black hole" on the sound of the raw takes. As of today, the industry does not have a "mechanical" way to correct this (that is what we were talking about on the "timbre solfege" post). There is no known solution to this other than the engineer fixing it "by ear". Our research project is about developing a methodology that will allow us to deal with this "black hole" in a more objective manner, but checking the quality of the results is still something that has to be done "by ear", which is what we are trying to do here with this giveaway.
