The S.O.U.N.D. Project is a podcast by Haverstick Designs that promotes discussions about acoustical topics involved with designing recording studios and other acoustical spaces. We will review tips and tricks to get the most out of your space acoustically, case studies of rooms we have completed, progress reports on rooms we are currently working on, along with interviews with artists, studio owners, and leading manufacturer representatives. We are excited to take this journey with you, and thank you for being a part of The S.O.U.N.D. Project!
