MMAC: A Massive Multi-dimensional Benchmark for Audio Captioning
Researchers introduce MMAC, a benchmark with 5,638 audio clips across six capability categories and fifteen evaluation dimensions to improve open-ended audio captioning.
- MMAC contains 5,638 audio clips sourced from over 20 datasets.
- It covers six capability categories and fifteen evaluation dimensions.
- The benchmark enables detailed diagnosis of coverage and reliability for audio captioning models.
- Provides a standardized, multi-dimensional evaluation framework for the audio AI community.
Audio large language models are moving toward generating detailed, free-form descriptions of sound, but existing tests mainly measure generation quality or task performance, leaving gaps in coverage and reliability assessment.
The newly proposed MMAC benchmark addresses these gaps by assembling 5,638 audio clips drawn from more than 20 data sources. It organizes the material into six capability categories and evaluates models along fifteen distinct dimensions, providing a granular view of how well a system captures various aspects of audio.
By offering this multi-dimensional evaluation framework, MMAC enables researchers and developers to diagnose specific strengths and weaknesses in their audio captioning models, fostering progress toward richer, more accurate descriptions.
The benchmark is publicly available, encouraging broader adoption and comparison across the community, and sets a new standard for future audio captioning research.
Offers a detailed test suite to benchmark and refine audio captioning models.
Supplies a rich dataset for academic projects on audio understanding.
Raises the bar for evaluating AI systems that describe sound.
