MusicLM is an advanced AI model developed by Google Research that generates high-fidelity music from textual descriptions, such as “a calming violin melody backed by a distorted guitar riff.” By framing music generation as a hierarchical sequence-to-sequence modeling task, MusicLM can produce music at a high resolution of 24 kHz that maintains consistency over several minutes. This model not only surpasses previous systems in terms of audio quality and fidelity to text descriptions but also supports the conditioning of generated music on both text and melody inputs, allowing for the transformation of hummed or whistled melodies based on stylistic text descriptions.
