Soundbug is an audio editor that can be used to visualize, inspect, analyze, and transform sound files. The application operates on individual files, much like a classic sound editor, but with a few modern twists. For starters, Soundbug embraces the notion of dynamic processing (i.e. effects with parameters that change over time) by offering control lines that can be attached to effects parameters, much like automation in a digital audio workstation. Control lines can be drawn manually, edited freely, saved to disk, and even loaded against different files. Furthermore, Soundbug offers a variety of operations to analyze audio and extract features from it. The results of time-varying analyses appear as control lines, which can be linked to processing parameters, providing a direct connection between qualities inherent in the sound and the processing that is being applied. In addition to a variety of non-real-time processes, Soundbug supports audio unit plugins and includes the BoOm Audio Units, which is a constantly growing suite of plug-ins.
