Model Details
This is a text-to-audio grounding model. Given an audio clip and a text prompt describing a sound event, the model predicts the event's probability with a time resolution of 40ms.
It is trained on AudioCaps. It takes a simple architecture: Cnn8Rnn audio encoder + single embedding layer text encoder.
Usage
import torch
import torchaudio
from transformers import AutoModel
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = AutoModel.from_pretrained(
"wsntxxn/cnn8rnn-w2vmean-audiocaps-grounding",
trust_remote_code=True
).to(device)
wav1, sr1 = torchaudio.load("/path/to/file1.wav")
wav1 = torchaudio.functional.resample(wav1, sr1, model.config.sample_rate)
wav1 = wav1.mean(0) if wav1.size(0) > 1 else wav1[0]
wav2, sr2 = torchaudio.load("/path/to/file2.wav")
wav2 = torchaudio.functional.resample(wav2, sr2, model.config.sample_rate)
wav2 = wav2.mean(0) if wav2.size(0) > 1 else wav2[0]
wav_batch = torch.nn.utils.rnn.pad_sequence([wav1, wav2], batch_first=True).to(device)
text = ["a man speaks", "a dog is barking"]
with torch.no_grad():
output = model(
audio=wav_batch,
audio_len=[wav1.size(0), wav2.size(0)],
text=text
)
# output: (2, n_seconds * 25)
