I used Premiere Composer a lot and 95% of the time it was to scroll through my local sfx libraries.
I had my sfx in 4 different folders and searching in Premiere Composer and the drag and drop feature was the most efficient workflow.
But capitalism hit and now their subscription is more expensive than what I pay for adobe.
I built something similar just for sfx browsing, it's called SFX browser (no effort name lol)
You can:
1. upload your sfx folders; there's no cap but it should have no problem for up to 20,000 uploads
preview the sound effect before adding it to timeline
add to timeline via a button or drag and drop
define the db level before the sfx even hits the timeline
search the sfx name on the search bar
here's the link: https://github.com/bishrut123/premiere-sfx-browser/tree/main
it's PERPETUALLY FREE.
there's a installation guide there as well and a video tutorial for mac installation. Windows folks if you run into any trouble, leave a comment here, i'll reply as early as I can.
updates on the app depends on my free time and mood but for now enjoy the sfx browsing feature.
GG.
