Myself and Glenn from halflife2.net got a chance to sit down with Mike Morasky, audio producer and sound engineer at Valve Software. We spoke for a solid two hours about everything ranging from his roots in music, working at Valve, techniques used in Portal 2, sound design and technical information about his work. There are some great details in this interview including what happened with Kelly Bailey, SDK information and OST information. This is a great listen for anyone who is interested in music and audio production in video games or any Valve fan.
Head over and give it a listen.
