Default Is this glitch ?

Hi,

Is this glitch ? Or wrong data format ?
There are also very little negative spikes, but not visible in the photo.
It is a PCM53 @ -60dB @ 1kHz without deglitcher and without filter, with 4 x oversampling.
Strong distortion on the analyzer.

Nobody ?

It is crossover distortion on zero, but the same chip does not produce it in another player.

-60dB means full scale/1000

your signal is 200mV pp, can't be -60dB, unless your full scale is 200V pp
