Had, to share this. FMOD Studio audio content creation tool is FREE.
From site: FMOD Studio is an audio content creation tool for games, with a focus on a ‘Pro Audio’ approach. It has an entirely new interface that will be more familiar to those using professional Digital Audio Workstations than existing game audio tools and is loaded with new features.
Apparently they made it free to Indie game dev's with projects under 100,000.
