Title: New AI Models for Music Generation: A Breakthrough in Audio Generation
The field of computer vision and natural language processing witnessed remarkable growth last year, leading researchers to explore the potential of deep learning and large language models (LLMs) in audio generation. In the past few weeks, four groundbreaking papers have been released, unveiling innovative models that simplify research in this area.
Subheading: MusicLM – High-Quality Music Generation from Text Descriptions
Researchers from Google and IRCAM – Sorbonne Universite have developed MusicLM, a model capable of producing top-notch music based on text descriptions like “a soothing violin melody supported by a distorted guitar riff.” MusicLM can generate 24 kHz music that remains constant for several minutes. This model can be trained on both text and melody, allowing it to match the pitch and tempo of a hummed or whistled tune with a captioned text. MusicCaps, a dataset with detailed music-text pairs, enhances the training process.
Subheading: SingSong – Creating Instrumental Music to Accompany Vocals
SingSong, proposed by Google researchers, offers a system that generates instrumental music to accompany input vocal audio seamlessly. By utilizing advancements in source separation and generative audio modeling, the team divided a massive musical dataset into aligned pairs of voice and instrumental sources. SingSong employs AudioLM, an audio-generative model, to generate instrumentals based on vocals. Noise addition and selective feature strategies further enhance the performance of isolated vocals.
Subheading: Moûsai – Long-Context Music Generation Based on Text Inputs
Moûsai, developed by researchers from ETH Zürich and Max Planck Institute for Intelligent Systems, introduces a text-conditional cascading diffusion model capable of constructing long-context 48kHz stereo music. This model utilizes a two-stage cascading diffusion technique to compress the audio waveform while maintaining high quality, making it efficient for real-world applications.
Subheading: AudioLDM – State-of-the-Art Text-to-Audio Generation
The University of Surrey, in collaboration with Imperial College London, presents AudioLDM, a text-to-audio (TTA) system that achieves remarkable generation quality. Using mel-spectrogram-based variational auto-encoder, AudioLDM can learn to construct the audio prior in a latent space. This model demonstrates superior TTA performance with minimal resources, outperforming existing baseline models.
Subheading: EPIC-SOUNDS Dataset – A Comprehensive Collection of Everyday Noises
The University of Oxford and the University of Bristol release EPIC-SOUNDS, a vast dataset of everyday noises. This dataset includes 100 hours of footage from residential kitchens, enabling research in audio/sound recognition and sound event detection. The aim is to tackle acoustic challenges with auditory descriptions.
These innovative AI models for music generation hold immense potential for transforming the music industry. While concerns regarding deep hazards exist, these models prove valuable for music creators, enabling faster generation of ideas and experimentation with new sounds and styles. However, human musicians still possess unique artistry and nuance that machines cannot replicate. The future of music creation lies in a harmonious collaboration between human musicians and AI technologies.
