Reaper: Render Audio

Sometimes too many VST’s can clog up your PC/Laptop this usually manifests itself in spluttering audio and audio dropouts – freezing or rendering these tracks to audio helps relieve your processor and increase your options.

Tip: Make a backup of your file before you do anything drastic – make a new copy of your song as well and rename it.

The way I usually do this is like so,

1. Original File = song.rpp

2. Backup File = song_backup.rpp

3. Rendered File = song_render.rpp

This may seem excessive but get yourself into the practice of backing up everything,
