>>> num_channels = 1
>>> num_frames = sample_rate * wav_duration
>>> wav_data = paddle.linspace(-1.0, 1.0, int(num_frames)) * 0.1
>>> waveform = wav_data.tile([num_channels, 1])
>>> base_dir = os.getcwd()
>>> filepath = os.path.join(base_dir, "test.wav")

>>> paddle.audio.save(filepath, waveform, sample_rate)
>>> wav_info = paddle.audio.info(filepath)
