Mutagene has released beta version 0.2.0 of lipredemuco, a new free Mac OS X VST plug-in.
lipredemuco is similar in some respects to Mutagene's original mWarped Linear Prediction filter. The filter has 4 inputs and 4 outputs.
In modes 1 & 2 ("code td" and "code fd"), it transmits side information on output channels 3&4. In modes 4 & 5 ("decode td" and "decode fd") it process input channels 3&4 to "reconstruct" channels 1&2. In mode 3 ("code+decode") only channels 1&2 are used and no side information is passed or processed.
The plugin is not attempting to be a codec simulation and transparent coding/decoding is likely impossible.
Price: Free.
