As input to ``forward`` and ``update`` the metric accepts the following input - ``preds`` (:class:`~torch.Tensor`): float tensor with shape ``(...,time)`` As output of ``forward`` and ``compute`` the metric returns the following output - ``nisqa`` (:class:`~torch.Tensor`): float tensor reduced across the batch with shape ``(5,)`` corresponding to overall MOS, noisiness, discontinuity, coloration and loudness in that order .. hint:: Using this metric requires you to have ``librosa`` and ``requests`` installed. Install as ``pip install librosa requests``. .. caution:: The ``forward`` and ``compute`` methods in this class return values reduced across the batch. To obtain values for each sample, you may use the functional counterpart :func:`~torchmetrics.functional.audio.nisqa.non_intrusive_speech_quality_assessment`. Args: fs: sampling frequency of input Raises: ModuleNotFoundError: If ``librosa`` or ``requests`` are not installed Example: >>> import torch >>> from torchmetrics.audio import NonIntrusiveSpeechQualityAssessment >>> _ = torch.manual_seed(42) >>> preds = torch.randn(16000) >>> nisqa = NonIntrusiveSpeechQualityAssessment(16000) >>> nisqa(preds) tensor([1.0433, 1.9545, 2.6087, 1.3460, 1.7117]) References: - [1] G.
