• Abstract: HARP 2.0 brings deep learning models to digital audio workstation (DAW) software through hosted, asynchronous, remote processing, allowing users to route audio from a plug-in interface through any compatible Gradio endpoint to perform arbitrary transformations. HARP renders endpoint-defined controls and processed audio in-plugin, meaning users can explore a variety of cutting-edge deep learning models without ever leaving the DAW. In the 2.0 release we introduce support for MIDI-based models and audio/MIDI labeling models, provide a streamlined pyharp Python API for model developers, and implement numerous interface and stability improvements. Through this work, we hope to bridge the gap between model developers and creatives, improving access to deep learning models by seamlessly integrating them into DAW workflows.

• Designing Neural Synthesizers for Low-Latency Interaction [8.27756937768806]
  We investigate the sources of latency and jitter typically found in interactive Neural Audio Synthesis (NAS) models. We then apply this analysis to the task of timbre transfer using RAVE, a convolutional variational autoencoder. This culminates with a model we call BRAVE, which is low-latency and exhibits better pitch and loudness replication.

  AudioX is a unified Diffusion Transformer model for Anything-to-Audio and Music Generation. It can generate both general audio and music with high quality, while offering flexible natural language control. To address data scarcity, we curate two datasets: vggsound-caps with 190K audio captions based on the VGGSound dataset, and V2M-caps with 6 million music captions derived from the V2M dataset.

  This paper exploits the zero-shot capabilities of pre-trained large language models (LLMs) for music genre classification. The proposed approach splits audio signals into 20 ms chunks and processes them through convolutional feature encoders. During inference, predictions on individual chunks are aggregated for a final genre classification.

  multimodal generative modeling has created milestones in text-to-image and text-to-video generation. Its application to audio still lags behind for two main reasons: the lack of large-scale datasets with high-quality text-audio pairs, and the complexity of modeling long continuous audio data. We propose Make-An-Audio with a prompt-enhanced diffusion model that addresses these gaps.
