How can I boost the bass of a video?
On my MacBook I’d use ffmpeg
ffmpeg -i in -af bass=g=15 out
But I haven’t found ffmpeg in the App Store for my phone.
iMovie on iPhone seems next to useless.
So, how can I change the audio EQ of videos on my phone?
I tried some online site but it errors every time so it’s probably broken, another site wants me to sign up which I don’t want to do. I couldn’t find an app for this myself, and the only way to get ffmpeg is apparently by jailbreaking but there’s no jailbreak for iOS 11.4.1 yet.
