As mentioned in the README, high filter orders can create unstable situations that result in loud, high-pitched noises. To protect users' hearing, I should add a simple peak limiter to the plugin itself.

When the buffer size is changed, the plugin adjusts, but chunks of audio are briefly played out of order as a result of buffer read/write positions changing. Adding some sort of interpolation or filter on the parameter might help.

Potential waveforms to try:

• Sawtooth
• Square (or pulse with adjustable width)
• Custom (allow user to open an audio file containing the desired waveform)

From the LV2 github wiki:

https://github.com/x42/robtk - Robin's LV2 UI ToolKit. x42. Robin doesn't recommend using.

So far, robtk has worked fine, but if this is true I still might want to consider AVTK, BWidgets, Redkite, or another toolkit that is designed for use by third-party plugins.

At large buffer sizes, xruns can occur. I need to figure out how to better divide the work over the time given by the DAW. The solution could involve multithreading or LV2 Workers, but I'm not sure how well thread scheduling works within a realtime audio context.

Currently, the Makefile only specifies the compilation settings for Linux. LV2 and the robtk toolkit do work on other platforms, so support for Windows or Mac is possible.

Currently, the graph on the left side of the UI displays nothing. I need to figure out how to use LV2 Atoms to communicate the appropriate information to the plugin UI to display a plot of the frequency response.
