Been using VideoVerb: Add Reverb to Video for a couple months now. It’s basically an app that lets you import videos and add all kinds of reverb effects to the audio. Pretty solid app if you’re into video editing or music production.
Here’s what you do: you just pick a video, choose from a bunch of different reverb presets, and adjust the intensity. There’s also a custom reverb mode where you can tweak a ton of settings to dial in your own sound. Took me a while to figure that part out but it’s really useful.
Look, if you make videos or work with audio, you’ll probably like this. It’s not perfect – the free version has ads which can get annoying – but overall it does the job. Worth checking out if you need to add some nice reverb to your videos.
