# MMAU


## Overview

MMAU (Massive Multitask Audio Understanding) is a comprehensive benchmark for evaluating audio understanding capabilities of multimodal large language models across diverse audio tasks.

## Task Description

- **Task Type**: Audio Understanding (Multiple Choice)
- **Input**: Audio recordings with multiple-choice questions
- **Output**: Correct answer choice (A/B/C/D)
- **Categories**: Speech, Sound, Music

## Key Features

- Large-scale audio understanding benchmark
- Covers multiple audio domains (speech, environmental sounds, music)
- Multiple-choice format with 4 options
- Includes both mini and full test sets
- Per-category accuracy reporting

## Evaluation Notes

- Default configuration uses **test_mini** split
- Primary metric: **Accuracy** (exact match on predicted letter)
- Reports overall accuracy and per-task-category accuracy
- Prompt includes chain-of-thought instruction

{choices}
```

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets mmau \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['mmau'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
