As in *ALL THE AUDIO*
I pretty much single-handedly sound designed an entire game solo, minus the music that I contracted out with a great composer, for a well-known AAA publisher / developer. Contracted out the VO recording and initial editing / sorting, and in handled 100% of the voice talent casting.
Any audio asset that went into the game passed through my hands for work / processing / massaging before it went into the game.
Was smart during my career and personally purchased all the sound libraries I used, that I still own licenses for today - At least 6TB just sound effects alone - No music assets at all. The sound libraries will be fun to use for sample-heavy music electronic music production.
I can't tell you how much I've invested just in audio software / plugins / instruments / microphones. Enough to last me the rest of my life, easily.
Anyway, I tend to ramble on... Sorry about that.
