## Installation

1. Install via pip
 ```
 pip install audiobox_aesthetics
 ```

2. Install directly from source

 This repository requires Python 3.9 and Pytorch 2.2 or greater. To install, you can clone this repo and run:
 ```
 pip install -e .
 ```

## Pre-trained Models

Model | S3 | HuggingFace
|---|---|---|
All axes | [checkpoint.pt](https://dl.fbaipublicfiles.com/audiobox-aesthetics/checkpoint.pt) | [HF Repo](https://huggingface.co/facebook/audiobox-aesthetics)

## Usage

### How to run prediction using CLI:

1. Create a jsonl files with the following format
 ```
 {"path":"/path/to/a.wav"}
 {"path":"/path/to/b.flac"}
 ...
 {"path":"/path/to/z.wav"}
 ```
 or if you only want to predict aesthetic scores from certain timestamp
 ```
 {"path":"/path/to/a.wav", "start_time":0, "end_time": 5}
 {"path":"/path/to/b.flac", "start_time":3, "end_time": 10}
 ```
 and save it as `input.jsonl`

2. Run following command
 ```
 audio-aes input.jsonl --batch-size 100 > output.jsonl
 ```
 If you haven't downloade the checkpoint, the script will try to download it automatically. Otherwise, you can provide the path by `--ckpt /path/to/checkpoint.pt`

 If you have SLURM, run the following command
 ```
 audio-aes input.jsonl --batch-size 100 --remote --array 5 --job-dir $HOME/slurm_logs/ --chunk 1000 > output.jsonl
 ```
 Please adjust CPU & GPU settings using `--slurm-gpu, --slurm-cpu` depending on your nodes.


3. Output file will contain the same number of rows as `input.jsonl`. Each row contains 4 axes of prediction with a JSON-formatted dictionary. Check the following table for more info:
 
 Axes name | Full name
 |---|---|
 CE | Content Enjoyment
 CU | Content Usefulness
 PC | Production Complexity
 PQ | Production Quality
    
 Output line example:
 ```
 {"CE": 5.146, "CU": 5.779, "PC": 2.148, "PQ": 7.220}
 ```

4. (Extra) If you want to extract only one axis (i.e. CE), post-process the output file with the following command using `jq` utility: 
    
    ```jq '.CE' output.jsonl > output-aes_ce.txt```


### How to run prediction from Python script or interpreter

1. Infer from file path
```
from audiobox_aesthetics.infer import initialize_predictor
predictor = initialize_predictor()
predictor.forward([{"path":"/path/to/a.wav"}, {"path":"/path/to/b.flac"}])
```

2. Infer from torch tensor
```
from audiobox_aesthetics.infer import initialize_predictor
predictor = initialize_predictor()
wav, sr = torchaudio.load("/path/to/a.wav")
predictor.forward([{"path":wav, "sample_rate": sr}])
```

## Evaluation dataset
We released our evaluation dataset consisting of 4 axes of aesthetic annotation scores. 

Here, we show an example of how to read and re-map each annotation to the actual audio file.
```
{
 "data_path": "/your_path/LibriTTS/train-clean-100/1363/139304/1363_139304_000011_000000.wav", 
 "Production_Quality": [8.0, 8.0, 8.0, 8.0, 8.0, 9.0, 8.0, 5.0, 8.0, 8.0], 
 "Production_Complexity": [1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 
 "Content_Enjoyment": [8.0, 6.0, 8.0, 5.0, 8.0, 8.0, 8.0, 6.0, 8.0, 6.0], 
 "Content_Usefulness": [8.0, 6.0, 8.0, 7.0, 8.0, 9.0, 8.0, 6.0, 10.0, 7.0]
}
```
1. Recognize the dataset name from data_path. In the example, it is LibriTTS.
2. Replace "/your_path/" into your downloaded LibriTTS directory. 
3. Each axis contains 10 scores annotated by 10 different human annotators.
