LETHE (Latent-parameter Evolution with Temporal Hierarchical quasi-Equilibrium) is a sonic-oblivion system designed for audio processing. It uses a 3 x 3 mixing matrix with two delay lines, where coefficients and delay times evolve via interaction between a linear discriminator and a random-perturbation optimizer.
The discriminator compares current energy behavior with an archive of the initial state, guiding parameter updates in a closed feedback loop. The system can mix circular, fixed, and live sources independently, allowing for flexible audio synthesis.
This architecture is situated within self-referential electroacoustic music, where the sonic outcome depends on an adaptive loop defined by the composer. It operates without external datasets or supervision after initialization, emphasizing autonomous evolution.
Why it matters: This approach demonstrates a GAN-inspired method for evolving audio parameters in a closed system, relevant for engineers interested in autonomous audio synthesis and self-referential models.
