New, free TechAudioTools lets you get serious with Unreal’s MetaSounds

MetaSounds is a powerful platform for sound, synthesis, and procedural audio and music. And the price is right (free). But in the past, it had some gaps in out-of-the-box functionality. Epic has quietly released TechAudioTools Content, a bunch of free editor tools and widgets that anyone interested in Unreal or MetaSounds should go grab right this second. It’s always the little things.

ANIMEVOX by castpixel is a free retro anime-style sound fx generator

Sparkle! Slash! PowerUP! This deceptively simple, stupidly fun free browser tool/download generates sound effects in the style of 80s and 90s Japanese animation, all thanks to a clever signal chain. And you can export WAV files, so you could use it to build instruments/drum racks, too.
