为什么在使用Pro Tools聚集音频或者内置音频时声音会出现抖动？

Core Audio在没有警报的情况下设置成44.1kHz时可能会出现抖动的情况。有时在Pro Tools中发生CPU过载错误之后会出现抖动。可以在Audio MIDI实用程序设置中进行修正，选择或重设为48kHz

Why is my audio jittery using Pro Tools aggregate or built-in audio?

This can occur when Core Audio changes to 44.1 kHz without warning. This will sometimes happen after a CPU Overload Error in Pro Tools. This can be corrected in the Audio MIDI setup utility. Select or re-select 48 kHz.
