What are we already doing?

Here are some of the improvements that we are already working on.

  • We are stripping Orinj version 2 of its license requirements so that we can provide it for free.
  • We are augmenting our finite impulse response filter applet to allow users to compare filters.
  • We are reviewing music theory topics on our wiki to add information on scale modes and chords.
  • We are implementing a plug-in framework for Orinj version 3 to allow other developers to run their own DSP effects through Orinj.

What are our future plans?

Here are some of our plans for future improvements.

  • We are discussing how to open the source code of Orinj, Scales, and our FIR applet to the public.
  • We are exploring options for a new wiki that allows easier collaboration between users with better topic administration, tagging, and proper wiki markup.
  • We are planning on a series of articles to explain the intricacies of designing digital compressors, reverbs, delays, choruses, and equalizers.
  • We would like to develop versions of Orinj and Scales for the iPhone and iPad.
  • We want to explore the design of infinite impulse response (IIR) filters.
