Meta Open-sources Generative AI Tool MusicGen that Can Create Music from Text Prompts

Meta, the renowned technology company behind various groundbreaking innovations, has recently unveiled its latest achievement in the field of artificial intelligence as it open-sources MusicGen to create music from text prompts. This open-source AI-powered music generator has the remarkable ability to create unique compositions based on text prompts.

Meta Open-sources Generative AI Tool MusicGen That Can Create Music from Text Prompts

How MusicGen Works

MusicGen operates by leveraging a cutting-edge AI model trained on an extensive dataset of licensed music. The training process involved analyzing a vast collection of 20,000 hours of high-quality music tracks, including Meta’s internal dataset as well as tracks sourced from Shutterstock and Pond5. This diverse corpus of musical styles and genres empowers MusicGen to offer a wide range of creative possibilities.

To optimize performance, Meta employed their 32Khz EnCodec audio tokenizer, which breaks down the music into smaller chunks. This enables parallel processing, resulting in faster and more efficient music generation. Users can input various text prompts, such as a specific genre or melody, to guide MusicGen in producing a composition that aligns with their desired musical direction.

Furthermore, MusicGen allows users to provide a reference audio file, which serves as a blueprint for generating new music. By aligning the generated composition with the reference track, MusicGen offers a unique opportunity to create harmonious pieces that resonate with established melodies or songs.

Meta’s MusicGen vs Google’s MusicLM

Google too launched its own text to music generator MusicLM at Google I/O 2023 so let’s compare these products:

Model typeSingle-stage (Music generation all at once)Hierarchical (Music generation in parts)
Training dataMusic scoresAudio recordings
AvailabilityOpen sourceNot open source
StrengthsQuick and easy to use, can generate music in a variety of stylesHigh-quality music that sounds like real-world recordings
WeaknessesCan be less accurate than MusicLM, may not be able to generate music in all stylesLimited to Google employees and select partners.

Benefits of MusicGen

Here are some specific examples of how MusicGen can be used to benefit musicians and music producers:

  • A beginner musician can use MusicGen to learn about different musical styles and techniques. They can experiment with different prompts and see how MusicGen generates different results. This can help them to develop their own musical style and to learn new techniques.
  • An experienced musician can use MusicGen to experiment with different melodies, rhythms, and harmonies. This can help them to come up with new ideas for songs that they would not have thought of on their own.
  • A music producer can use MusicGen to generate different styles of backing tracks, which can be used to create a variety of different moods and atmospheres.

Limitations of MusicGen

Variable Output Quality: While MusicGen endeavors to generate high-quality music, the AI system’s output may not always meet users’ expectations. Due to the complex nature of music composition and individual preferences, some generated pieces may fall short in terms of perceived quality.

As Meta open-sources MusicGen to create music from text prompts, it signifies a significant milestone in the realm of generative AI tools for music creation. As musicians and producers increasingly embrace AI-driven technologies, MusicGen offers a promising avenue for exploration and innovation.
