Sharing my Linux-based Software DSP app for IIR DSP, Loudspeaker Crossovers

[charlielaub]

I have decided to share my DIY software DSP app "GStreamer Streaming-Audio System Controller" (GSASysCon) with the greater community. It's something I have been using and slowly modifying and enhancing for the last 10 years or so, and it's very stable and reliable. Features include multiple-playback endpoints, synchronous playback, and streaming to remote clients (e.g. other computers on your LAN). A recent addition are "shortcut" names for a wide variety of loudspeaker filters. There are several help documents available that describe all the features and functionality of the app, as well as a setup guide to get you started.

The app automatically builds and launches GStreamer pipelines using GStreamer's command-line interface based on the user configuration. IIR filtering is provided by my ACDf LADSPA filters, which are included with the package. Configuration of routing and DSP is via text-based files. There is also a text-based user interface for controlling playback and basic volume control. It can also be called in a non-interactive mode.

The primary online thread can be found at DIY audio, however, I often log in here and you are welcome to PM me with questions or issues, or simply post in this thread.
