With a Dedicated App, the DC01 Achieves 64-Step Hardware Volume
Windows 10 and Android 5.0 and above support the UAC2.0 protocol by default. However, for compatibility reasons, Android Smartphone manufacturers still use SRC on audio output. When DC01 is connected, the maximum volume is achieved by default, the software algorithm of the device is used to reduce the volume. The software algorithm can reduce the volume but cannot reduce the noise floor. Therefore, iBasso developed a UAC2.0 volume controller app to achieve 64-step hardware volume control, effectively reducing the noise floor while achieving a better audio performance.
