🐛 Bug Report

    def get_bandwidth_per_quantizer(self, sample_rate: int):
        """Return bandwidth per quantizer for a given input sample rate.
        """
        return math.log2(self.bins) * sample_rate / 1000

it should be

        return math.log2(self.bins) * sample_rate / 1000 / self.hop_length

My bad. sample_rate is already divided by sample rate.
