recordings
Audio and video productions by Bartłomiej Mróz - immersive recordings, concert archives, and mixing work.
Beyond research, I work as a recording engineer and producer – primarily in immersive and spatial audio formats. This page collects productions I have authored, co-produced, or had a principal technical role in.
