Perfecting real-time adaptive audio soundtracks, from tone to cadence, has become an essential tool for brands to produce ads running across large language models and AI-powered platforms.

Earlier this week, Google introduced Lyria 3, its latest AI music generator developed in collaboration between developers at Gemini and Google DeepMind. It powers the "Dream Track" feature for YouTube Shorts, enabling creators to generate royalty-free, customized soundtracks.

Lyria 3 can generate music from either photos or text. The text-to-track feature allows users to specify a genre, mood, inside joke or memory, and then creates a track with lyrics or instrumentals based on prompts. for example, a user can say, “Make a song for my mother about our childhood memories and her delicious home-cooked plantains.”

Just prior to this tool being released, news broke that David Greene, longtime host of NPR’s “Morning Edition,” sued Google, alleging that Google’s NotebookLM tool is based on Greene’s podcast voice, according to The Washington Post.
Gemini's audio outputs are limited to 30 seconds, at least for now. Google introduced the tool as a fun and quirky music creator, rather than something brands use in ads.

Lyria 3 simplifies the process of creating music, allowing users to generate high-quality audio tracks across a range of genres -- from short jingles to lo-fi beats, or intricate songs.

Users describe an idea or upload a photo. For example, they can describe “a humorous R&B slow jam about a sock finding its match” and Gemini produces a professional track, complete with style-specific lyrics, vocals, and tempo.
