CsoundQt

CsoundQt is a cross-platform integrated development environment (IDE) and graphical frontend for the Csound audio programming language. It is built with the Qt application framework and provides a user interface for writing, editing, and running Csound scores and instrument definitions. It is designed to simplify composing and testing Csound work by combining an editor, an instrument/opcode browser, and runtime controls in a single application.

Key features include an editing area with syntax highlighting and auto-indentation for Csound language, code completion and inline documentation, a project manager for organizing multiple csd files, and a built-in browser of Csound opcodes and help topics. It can launch Csound in real-time mode for live auditioning of changes, render audio to files, and display basic visualizations such as the output waveform when available. It supports multi-file projects, external editors, and can work with various versions of Csound.

CsoundQt is available for Windows, macOS, and Linux. It requires a Csound installation to be present on the system and communicates with the Csound engine to compile and run scores. It is maintained as an open-source project, with releases hosted on its distribution channel and shared with the broader Csound community. Users commonly employ CsoundQt as a convenient editor and control panel for developing, debugging, and performing with Csound.
