 ====== Proposals that have been implemented ======
+===== Audio Frequency Node (Kenneth ;) =====
+Implemented in April/May 2020
+Load audio files, use FFT to extract the amplitude at specific frequencies and expose them as scalar values.
+The result of the FFT computation will be cached in memory for best performance, allowing any frequency to be extracted from the same audio file at any time. The cache is shared between plugins.
+There will also be a channel modifier.
+Multiple audio files are supported. The allowed file formats will depend on the library we'll use for that, but at least include WAV. The choice of libraries to use will depend on their licensing. The LGPL is, unfortunately, out of the question as it would add additional files to distribute and install.
