What is Lyria 2?

Lyria 2 is the third generation of Google DeepMind's AI music creation tools, as a core component of the Vertex AI platform, is centrally positioned as an omnimodalmusic compositionThe model realizes for the first time the full link coverage from text cue to high-fidelity audio generation. This model realizes for the first time the full link coverage from text cue to high-fidelity audio generation, supports dynamic real-time interaction and multi-style arranging, and is regarded as "the GPT-4 moment in the field of AI music" by the industry.

Lyria 2 Core Features

1. Full Modal Music Generation
   • Input form: Supports mixed input of text, MIDI, audio clips, and control parameters (e.g., BPM, modulation).
   • output qualityThe newest addition to the system is a new, more advanced version of the new audio system: it produces audio with a 48kHz sampling rate and 24-bit bit depth, which is comparable to professional studio standards.
   • Stylistic generalization: Based on a hierarchical style encoder, it supports cross-stylistic fusion generation (e.g. "electronic symphony") for 20+ music genres (e.g. jazz, classical, electronic).
2. Dynamic real-time interaction
   • Low latency generation: Achieve end-to-end latency <500ms on consumer GPUs such as the NVIDIA RTX 4060 with TensorRT acceleration and streaming inference, supporting scenarios such as live performances and live soundtracks.
   • Dynamic style migration: Users can trigger stylized extensions of the AI (e.g., automatically arranging a simple piano melody into a full rock band accompaniment) in real time via a MIDI controller or microphone input.
3. Parametric control
   • BPM Reconciliation: Supports ±20% dynamic adjustment.
   • Tuning Options: Covers the 12-tone scale and differential tones.
   • musical instrument combination: Specific instrument combinations can be specified (e.g. "Piano Solo without Drums").
4. modular toolchain
   • AI Melody Generation → AI Chord Generation → Artificial Recording: Support drag-and-drop combination of functional modules to lower the threshold of creation.
   • plug-in marketCompatible with VST, AU and other audio plug-in formats, seamlessly integrates with mainstream DAWs (e.g. Ableton Live, FL Studio).

Lyria 2 Usage Scenarios

1. Film/TV/Commercial Soundtracks
   • case (law): An independent director generates a dynamic soundtrack by entering script keywords (e.g., "suspenseful chase scene") at a reduced cost of 70%.
   • dominance: Supports real-time adjustments to match the mood of the screen.
2. Music Composition and Production
   • music producer: Quickly generate background music, sound effects or complete soundtracks to reduce production costs.
   • independent musician: Explore AI-assisted creation to break through bottlenecks of inspiration.
3. Corporate Branding Customization
   • demand (economics): Generate customized branded music to enhance user memory points.
   • realization: Quickly generate customized music by "brand keywords + emotion tags".
4. live performance
   • functionalityThe AI is triggered in real time by a MIDI controller to create a "one-man-band" effect.
   • case (law): A band on tour uses Lyria 2 to generate extended backing tracks in real time to enhance their performance.

Lyria 2 Operating Instructions

1. basic operation
   • Text-to-Music: Enter a text prompt (e.g. "80's retro electronica, BPM 120") to generate a full music clip.
   • Real-time interactive controlThe AI generates the accompaniment in real time: the melody is entered through the MIDI controller.
2. Advanced Features
   • Multi-style fusion: Specify multiple styles (e.g. "Jazz+Electronic") to generate cross-genre music.
   • emotional control: Modulate the direction of generation through emotion labels (e.g., "exciting", "melancholic").
3. Deployment and Compatibility
   • hardware requirement: NVIDIA RTX 3060 and above GPUs (RTX 4060 recommended).
   • software environment: Python 3.8+, TensorFlow 2.10+, CUDA 11.7+.
   • Model Download: Access to pre-trained models via the Google Vertex AI platform or Hugging Face Hub.
