请问：Sigma DSP 的 EQ 处理会影响 音频信号的相位吗？whether the EQ settings will change the audio signal phase?

EQ filters do have an effect on the signal's phase, as well as its amplitude. You can view this phase response in SigmaStudio using the stimulus and probe blocks. There is another post on this forum that describes the use of these blocks: http://ez.analog.com/message/5666#5666
