(self.melspectrogram_buffer, self._get_melspectrogram(list(self.raw_data_buffer)[-n_samples-160*3:]))

mel spectrogam should padding 240 left side if window size 400 or 352 if window size 512 (onnx file of mel spectogram has kernel size 512 not 400)

        self.melspectrogram_buffer = np.vstack(
            (self.melspectrogram_buffer, self._get_melspectrogram(list(self.raw_data_buffer)[-n_samples-240:]))
        )

and i think this should also pad with 240 or 352 depending on window size

self.raw_data_buffer: Deque = deque(maxlen=sr*10)

self.raw_data_buffer.extend([0] * 240)
