How to use the audiomentations.augmentations.transforms.AddImpulseResponse function in audiomentations

def test_dynamic_length(self):
        sample_len = 1024
        samples_in = np.random.normal(0, 1, size=sample_len).astype(np.float32)
        sample_rate = 16000
        augmenter = Compose(
            [AddImpulseResponse(ir_path=os.path.join(DEMO_DIR, "ir"), p=1.0)]
        )

        self.assertEqual(len(samples_in), sample_len)
        samples_out = augmenter(samples=samples_in, sample_rate=sample_rate)

        self.assertEqual(samples_out.dtype, np.float32)
        self.assertGreater(len(samples_out), len(samples_in))
