# 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

## Prompt Template
**Prompt Template:**
```text
Answer the following multiple choice question based on the audio content. The last line of your response should be of the following format: 'ANSWER: [LETTER]' (without quotes) where [LETTER] is one of {letters}. Think step by step before answering.
{question}
{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)
```
