SoundQ is a free Sound Effects library applicationhttps://www.prosoundeffects.com/soundq/ that obviously ties into Pro Sound Effects libraries of sound effects, but can also be used on your own local sound effects without a subscription or purchasing sound effects from them. And you can edit the sound effects and send it into premiere that way, or send the original and it will even copy the sound effect to your library (though I wish I could get it to put it automatically place it in the same place away from the project file (where it puts it automatically) since I use PostHaste to make templated for my projects I don’t want the sound files next to my project, but in the sound fx folder, but i will just have to manually move them.
And since a free subscription gives your some free sound effects, and it is also integrates with Freesound.org you can’t really complain.
Honestly this is just great to have, as I have missed Apple Soundtrack since it was EOLed when Final Cut Pro 7 left all those years ago.
