AudioMarathon: A Comprehensive Long-Form Audio Understanding Benchmark

Abstract

AudioMarathon is a large-scale, multi-task audio understanding benchmark designed to systematically evaluate audio language models' capabilities in processing and comprehending long-form audio content. It provides a diverse set of 10 tasks built upon three pillars: long-context audio inputs with durations ranging from 90.0 to 300.0 seconds, which correspond to encoded sequences of 2,250 to 7,500 audio tokens, respectively, full domain coverage across speech, sound, and music, and complex reasoning that requires multi-hop inference.

📊 Task Taxonomy & Statistics

Task Categories

AudioMarathon organizes tasks into four primary categories:

1. Speech Content Extraction -
2. Audio Classification
3. Speaker Information Modeling

🎯 Benchmark Objectives

AudioMarathon is designed to evaluate:

1. Long-Audio Processing: Ability to maintain coherence across extended audio sequences
2. Multi-Domain Generalization: Performance across diverse acoustic environments and tasks
3. Semantic Understanding: Comprehension of spoken content, not just acoustic patterns
4. Efficiency: Computational requirements for long-form audio processing
