Render Multiple Files With Their Own File Names In Reaper 

Here is how to render (save as) many separate files from a single Reaper project, and have each file saved with its own file name. It's a bulk (or batch) process. So it all happens at once, in the same Render action.
this is SUPER helpful if you have to split a single audio item into a bunch of smaller audio items (see my video on how to do that here: • Reaper Tutorial 2021: ... , and then each of those small sections has to be saved as a separate file with its own file name. Imagine having a job where you have to split a long audio into 90 smaller audios (I had this job), and then create 90 mp3 files and name all 90 files manually! That would take forever. So by using the process to split your audios into smaller ones (that linked video above), and then using the process in this video, you can create all those files in about 5 or 10 minutes. this can save you sooooo much time.
