The FL Studio Project (FLP) is a proprietary data format developed by Image-Line for its digital audio workstation, FL Studio. This format retains complete musical composition data, including MIDI sequences, instrument plugin settings, automation patterns, and audio mixing configurations required to render a track. While the format is binary-based and considered safe, it relies on the host application’s installed libraries and does not inherently contain the actual audio wave files used in the project.
