Overview

This repo contains the PyTorch implementation of Audio Flamingo 3: Advancing Audio Intelligence with Fully Open Large Audio-Language Models. Audio Flamingo 3 (AF3) is a fully open, state-of-the-art Large Audio-Language Model (LALM) that advances reasoning and understanding across speech, sounds, and music. AF3 builds on previous work with innovations in:

• Unified audio representation learning (speech, sound, music)
• Flexible, on-demand chain-of-thought reasoning (Thinking in Audio)
• Long-context audio comprehension (including speech and up to 10 minutes)
• Multi-turn, multi-audio conversational dialogue (AF3-Chat)
• Voice-to-voice interaction (AF3-Chat)

Extensive evaluations confirm AF3’s effectiveness, setting new benchmarks on over 20 public audio understanding and reasoning tasks.

Main Results

Audio Flamingo 3 outperforms prior SOTA models including GAMA, Audio Flamingo, Audio Flamingo 2, Qwen-Audio, Qwen2-Audio, Qwen2.5-Omni.LTU, LTU-AS, SALMONN, AudioGPT, Gemini Flash v2 and Gemini Pro v1.5 on a number of understanding and reasoning benchmarks.

Audio Flamingo 3 Architecture

Audio Flamingo 3 uses AF-Whisper unified audio encoder, MLP-based audio adaptor, Decoder-only LLM backbone (Qwen2.5-7B), and Streaming TTS module (AF3-Chat). Audio Flamingo 3 can take up to 10 minutes of audio inputs.

Installation

./environment_setup.sh af3

Code Structure

• The folder audio_flamingo_3/ contains the main training and inference code of Audio Flamingo 3.
• The folder audio_flamingo_3/scripts contains the inference scripts of Audio Flamingo 3 in case you would like to use our pretrained checkpoints on HuggingFace.

Each folder is self-contained and we expect no cross dependencies between these folders. This repo does not contain the code for Streaming-TTS pipeline which will released in the near future.

Single Line Inference

To infer stage 3 model directly, run the command below:

python llava/cli/infer_audio.py --model-base /path/to/checkpoint/af3-7b --conv-mode auto --text "Please describe the audio in detail" --media static/audio1.wav

To infer the model in stage 3.5 model, run the command below:

python llava/cli/infer_audio.py --model-base /path/to/checkpoint/af3-7b --model-path /path/to/checkpoint/af3-7b/stage35 --conv-mode auto --text "Please describe the audio in detail" --media static/audio1.wav --peft-mode
