Google has launched the Lyria 3.5 music generation model with the ability to edit individual sections of a track
Google has launched the Lyria 3.5 model in Google Flow Music with improved melodies, lyrics and vocals. The new Selective Section Painting feature allows users to edit a section of a track without regenerating it. Tracks last 30 seconds to 3 minutes; the company has not commented on the training data.
Google has launched a new music generation model, Lyria 3.5, in Google Flow Music. According to the company, it offers richer and more natural-sounding melodic structures, higher-quality lyrics with better adherence to prompts and song structure, and more expressive, emotionally convincing vocals with improved pronunciation. Users also have more precise control over the tempo and output length.
Tracks generated by the model can last from 30 seconds to 3 minutes. A new feature called Selective Section Painting allows users to edit a specific section of a track or expand a short melody into a full song without having to regenerate the entire track. Users can also fine-tune the tempo and duration of individual elements of a track, such as vocals, drums or bass.
Sources vary in how much detail they provide about the training data for the model. When Lyria 3 was first introduced, Google stated that it had trained the model on materials that Google and YouTube had rights to under terms of service, partner agreements and applicable laws, without providing further details. According to The Decoder, Google did not respond to a question about the training data specifically for Lyria 3.5.
Why it matters
The ability to edit individual sections of a track without having to regenerate the entire track shifts the workflow for AI-generated music from a one-off attempt to iterative editing, which has practical applications for content creators, video production and hobby musicians. At the same time, uncertainty about the training data persists, which is relevant to businesses considering licensing and copyright risks.
Two audiences, two different impacts
What this means
For individuals
Users creating music can now edit selected passages of a track or expand a short melody into a full song without having to regenerate the entire track, and set the tempo and duration of vocals, drums or bass more precisely.
For a business
Companies creating video content, advertisements or marketing materials can use Google Flow Music with the Lyria 3.5 model to create custom music with more precise control over length and edits to individual sections of a track, but the lack of transparency about the training data poses a risk for commercial use.
