FL Studio Guru - Freezing is the process of converting real-time CPU intensive synthesis and effects to much less CPU intensive Audio Clips. Additionally, freezing can be used to apply sample-slicing and other 'resampling' effects to the audio or simply to tidy up a messy Playlist.

 

 

FL Studio's free-form workflow means there is no sure relationship between Instrument Channels > Pattern Clips > Playlist tracks > Mixer Tracks. So, audio is 'frozen' at the Mixer stage and a little human intervention is needed to decide what to freeze.
