Abstract: Generative Models for Audio Synthesis have been gaining momentum in the lastfew years. More recently, parametric representations of the audio signal havebeen incorporated to facilitate better musical control of the synthesizedoutput. In this work, we investigate a parametric model for violin tones, inparticular the generative modeling of the residual bow noise to make for morenatural tone quality. To aid in our analysis, we introduce a dataset ofCarnatic Violin Recordings where bow noise is an integral part of the playingstyle of higher pitched notes in specific gestural contexts. We obtain insightsabout each of the harmonic and residual components of the signal, as well astheir interdependence, via observations on the latent space derived in thecourse of variational encoding of the spectral envelopes of the sustainedsounds.
