这是FREEZE在LOGIC AUDIO中的定义：
Freeze Tracks
Software Instrument and Audio Tracks now feature a „Freeze“ button (the small ice crystal icon) in the Arrange window. It can be used whenever the track utilizes a CPU-hungry Software Instrument and/or CPU-hungry effect plug-ins and the track’s arrangement is in a „near-final“ stage.
Freeze will automatically render the original combination of sound source (Audio Track or Software Instrument) and channel plug-ins (Effects) into an audio file. This process is invisible to the user, and an audio file will be played back in place of the original channel signal.
You can still change the volume, pan and send levels of this channel, but all plug-ins (including the Software Instrument if applicable) are „frozen“ — as they are rendered into the audio file.
Should the final mix require any changes to a frozen track, you can disable the „Freeze“ at any time, allowing you to tweak any plug-in parameter to your satisfaction before re-freezing the track. Please bear in mind the fact that the track will use the CPU resources required by the original „live“ version during editing.
只不过LOGIC AUDIO里你是看不到这个过程的，是虚拟的……
所以CUBASE SX的用户抱怨了，于是有人想出来这么一招……
