The Android audio curve call is set down from the ui. There are different UIS Based on stream audio, which are divided into 7 and 15 steps, corresponding to the actual step 100. For the conversion process, see the volIndexToAmpl function in AudioPolicyManagerBase. cpp. 4.1 The Calling process is different from the previous one, and the principle is the same. I think the previous version is linear, and the new version is a three-segment line. Why is it
