The pane also allows access and control over the player state including toggling of playing/paused and loop state, the current time, and the volume. The audio player supports ogg, mp3, and wav files If SciPy is installed, 1-dim Numpy Arrays and 1-dim Torch Tensors are also supported. The dtype must be one of the following - numpy: np.int16, np.uint16, np.float32, np.float64 - torch: torch.short, torch.int16, torch.half, torch.float16, torch.float, torch.float32, torch.double, torch.float64 The array or Tensor input will be downsampled to 16bit and converted to a wav file by SciPy.
