OpenAI has introduced two new audio models: Whisper, a highly accurate automatic speech recognition (ASR) system, and Jukebox, a neural net that generates novel music with vocals. Whisper is open-sourced and approaches human-level robustness and accuracy on English speech, while also offering multilingual and translation capabilities. Jukebox, while not real-time, allows users to generate music in various genres and artist styles, though it acknowledges limitations in consistency and coherence. Both models represent advances in AI's understanding and generation of audio, with Whisper positioned for practical applications and Jukebox offering a creative exploration of musical possibility.
The blog post introduces a novel method for sound synthesis on the web using a network of interconnected masses and springs, simulated in real-time using the Web Audio API. By manipulating parameters like spring stiffness, damping, and mass, users can create a wide range of sounds, from plucked strings and metallic pings to more complex textures. The system is visualized on the webpage, allowing for interactive exploration and experimentation with the physics-based sound generation. The author highlights the flexibility and expressiveness of this approach, contrasting it with traditional synthesis methods.
Hacker News users generally praised the project for its innovative approach to sound synthesis and its educational value in demonstrating physical modeling. Several commenters appreciated the clear explanation and well-documented code, finding the visualization particularly helpful. Some discussed the potential applications, including musical instruments and sound design, and suggested improvements like adding more complex spring interactions or different types of oscillators. A few users shared their own experiences with physical modeling synthesis and related projects, while others pointed out the computational cost of this approach. One commenter even provided a link to a related project using a mass-spring system for image deformation. The overall sentiment was positive, with many expressing interest in experimenting with the project themselves.
