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}])

How to load model using HuggingFace way (for finetuning, etc)

from audiobox_aesthetics.model.aes import AesMultiOutput
model = AesMultiOutput.from_pretrained("facebook/audiobox-aesthetics")
# finetune the model
...
# finished finetuning & upload the model
model.push_to_hub("<your_hf_username>/<your_hf_repo>")

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.
