Freeze and Render
Turning heavy tracks into audio ahead of time, and knowing when a frozen file can still be changed and when a render cannot.
Related
Freezing renders a track to audio and temporarily disables its plug-ins; rendering exports sound for good. Both trade disk for CPU, but one is reversible and the other is not.
The problem
Large sample libraries and long effect chains make a project stutter, especially while recording or adding parts. Freezing stops the real-time calculation for tracks that are already settled, until you need to change them again.
How it works
Freezing renders the whole track offline, including plug-ins and automation, then bypasses the original chain. Rendering writes a new file, either a finished mix or a set of stems. Freezing must respect side-chain and bus dependencies, so do not freeze a track another track still feeds.
Settings and judgement
Check side-chain sources, automation and sends before freezing. Leave headroom when rendering and do not sit at zero dB. After export, verify length, tail and sample rate. Keep tracks you still expect to revise unfrozen.
What to listen for
Compare before and after freezing. The difference should be noise floor and tail, not musicality. If freezing makes a track thin, look for a plug-in that was skipped.
Common misunderstandings
Freezing does not reduce audio quality; it calculates ahead of time. Rendering does not make a project unchangeable either. The project remains, but the exported file no longer writes back.
