Latent Timbre Synthesis

Fast Deep Learning tools for experimental electronic music
by Kıvanç Tatar, Daniel Bisig, and Philippe Pasquier

The model learns from a dataset of audio files and synthesizes sounds in real-time. The model let users to explore a universe of timbre that it learns from the dataset. More details of the Deep Learning framework is upcoming in a few weeks. 



Examples


Here are our initial generations. Original 1 and Original 2 are the excerpts of original samples. Well, these two tracks are actually generated only using the original magnitude spectrums, and phase is added after using a reconstruction technique. Likewise, our Deep Learning model generates only the magnitude spectrum, and phase is added later using a reconstruction technique. Hence, the original 1 and original 2 are our baselines, and they are the ideal qualities that the Deep Learning model aims to achieve during the training.

Reconstructions-> X Interpolations 0.0 and X Interpolations 1.0 are reconstructions of the original audio files using the Deep Learning model, original 1 and 2 respectively. 

Timbre Interpolations-> X Interpolations 0.1 means that this sample is generated using 90% of original 1 timbre and 10% of original 2 sample. Think 0.1 as a slider value...

Timbre Extrapolations-> X Extrapolations 1.1 means that we are drawing an abstract line between timbre example 1 and 2, and then following the direction of that line, we are moving further away from the timbre 2 by 10%. X Extrapolations -0.1 means we are drawing a line between timbre 2 and 1, and moving further away from timbre 1 in that direction by 10%.
