Raise (amplify) the peaks

Some compressor plug-ins can be configured to expand, but I don’t know of one off-hand… Maybe Audacity’s compressor can do it… I don’t know.

Chris’s Compressor can expand if you use a negative value for “compression ratio”.

Steve did make a “peak processor” nyquist plugin which will expand (or compress) peaks, see …

Peak Limiter / Expander

Obviously care needs to be taken with peak expansion to avoid clipping, but I noticed that excessive expansion can cause infinite or “not a number” (nan) sample values. This is not good. This version prevents infinite and “nan” values. For expansion settings the output level is limited to 0 dB which I think is the neatest way to handle the issue. peakprocess.ny (1.76 KB)

There is a VST plugin called “FloorFish” which is an expander … http://www.digitalfishphones.com/main.php?item=2&subItem=5
