I read about true peek only some weeks ago and i look to see Oscilloscope videos from Line Out or speaker or headphone out about it. because i do not believe it. But i find none. when rectangle signal in testtone generator is used the true peek Meters show +3.7 db or more with 14.4 khz testtone. but i want see what happen and i connect my 10 MHZ oscilloscope to headphone out, and there can not see higher peak and no clipping in the analog part. more text explain in the video text true peak Level Meters are wrong confirm with 10 MHZ Oscilloscope in this Video(no Videosound) - YouTube
