Analog Audio Limits


Hello, I am trying to find out what the limits are of the analog input for the BC127. As an experiment, I am inputting a 440 Hz signal into audio input, increasing the amplitude and seeing where the output on some bluetooth speakers begin to saturate. I understand you can adjust the analog gain through “SET AUDIO_ANALOG” but what is the output voltage limit such that you can predict audio clipping from an input? Assuming a 3.3V input.
