Researchers have conducted a systematic analysis of feature encoding within VAE-based audio decoders, specifically focusing on the Realtime Audio Variational autoEncoder (RAVE). Their study reveals that synthetic musical stimuli are encoded effectively across different models and audio features like pitch and BPM. While encoding strength is reduced with natural audio, it remains substantively apparent, particularly when using nonlinear probes. The findings indicate that encoding strength varies throughout the decoder layers, with middle layers showing an increased ability to jointly encode features. Similar patterns were observed in a general-purpose EnCodec model, suggesting broader applicability of these encoding characteristics in neural audio models and informing future control strategies for neural synthesis.
