Query: CRASH: Raw Audio Score-based Generative Modeling for Controllable
  High-resolution Drum Sound Synthesis   In this paper, we propose a novel score-base generative model for
unconditional raw audio synthesis. Our proposal builds upon the latest
developments on diffusion process modeling with stochastic differential
equations, which already demonstrated promising results on image generation. We
motivate novel heuristics for the choice of the diffusion processes better
suited for audio generation, and consider the use of a conditional U-Net to
approximate the score function. While previous approaches on diffusion models
on audio were mainly designed as speech vocoders in medium resolution, our
method termed CRASH (Controllable Raw Audio Synthesis with High-resolution)
allows us to generate short percussive sounds in 44.1kHz in a controllable way.
Through extensive experiments, we showcase on a drum sound generation task the
numerous sampling schemes offered by our method (unconditional generation,
deterministic generation, inpainting, interpolation, variations,
class-conditional sampling) and propose the class-mixing sampling, a novel way
to generate "hybrid" sounds. Our proposed method closes the gap with GAN-based
methods on raw audio, while offering more flexible generation capabilities with
lighter and easier-to-train models.
