Podcast Production · Audio Logo · Loudness Mastering

Breaking the Frame

Breaking The Frame is a Cologne-based photography and culture podcast hosted by Miss Souls - a queer female voice covering a community that rarely gets to speak for itself. Behind the scenes, the show runs on a production setup I helped build from the ground up: mic recommendations, file system, edit workflow, and a mix process designed for the reality of indie podcasting. That means cleaning up guest audio from WhatsApp and Zoom, leveling every voice to a consistent dynamic, and mastering to platform loudness targets so listeners never reach for the volume knob. The audio logo — the sound identity of the show — was composed and produced entirely in-house.
