Luthier |
culture, programming, generative |
Luthier is an experimental tool for generating sound synthesisers, which imitate a given sound sample. I'm building it as my master's thesis.
| Week & month | Goal |
|---|---|
| w1/02 | Test FFT algos in rust, try plotting them in real time in UI |
| w2/02 | Prepare any prototype of synth graph building UI |
| ... | |
| Half a semester passes.. | Busy with work |
| ... | |
| w8/05 | Wrote an actual working prototype in Python |
| w9/01 | Graph structure |
| w9/02 | Audio playback |
| w9/03 | Random graph generation, simple loss function |
| w9/04 | Control signals normalisation |
| w10/05 | Multithreading when optimising or searching through parameter space for benchmarks |
| w10/06 | Handcoding different FM synths and trying to optimise them by stupid-simple evolutionary algorithms |
| w10/07 | Graph colorisation & animations, integration with scipy.optimize |
| w11/01 | Normalised ADSR signals, reworked parameter setting. Basic one-operator FM optimised successfully! |
| w11/02 | Experiments with Frechet audio distance (abandoned, different use case than mine), rust ADSR, converting notebooks to the new rust backend |
| w11/03 | Notebook cleanup, UTs cleanup |
| w11/04 | Implemented simple virtual analog algorithms |
| w11/05 | Cheat day |
| w11/06 | Implemented a reverb node, successfully evolving a 2-oscillator virtual analog with reverb |
| w11/07 | basic version of generic synth genetic code |
| w12/01 | Making the presentation, evolving analog-FM hybrids |
| w12/02 | Progress presentation seminary |
| w12/03 | A break! |
| w12/04 | Consulting my thesis advisor, MVP has been reached, time to write the thesis! |
| w12/05 | |
| w12/06 | |
| w12/07 | |
| w13/01 | |
| w13/02 | |
| w13/03 | |
| w13/04 | Experimenting with analog modeling, sounds quite nice now |
| w13/05 | |
| w13/06 | Attepmting to recreate samples from Korg Minilogue, fix an insanely dumb bug with different sample rates across Python and Rust |
| w13/07 | Implementing delay, tweaking param ranges for ADSR |
| w14/01 | Testing spectrogram as target function |
| w14/02 | Testing different variations of MFCC and Fourier target functions, RMS/DTW flying all over the place |
| w14/03 | Consulted the current thesis state with the supervisor, looks good, chapter shuffling ahead |
| w14/04 | Restructured the thesis according to supervisor's directions |
| w14/05 | Equations in the problem definition chapter |
| w14/06 | Performed synthesis parameters cross-section tests of target functions |
| w14/07 | Found benchmarks of a previous thesis which I can use for comparison with my work |

Use a simple NxN matrix as a "patch bay". Pass a pointer to that matrix to each node as a mutable reference. Nodes know their own ID.
Question: how would they know the IDs of modulators? Maybe the matrix should not be a raw array (in a structural sense), but rather a mirror-like mapping (axis going across the array)?
