MeldaProduction MCompressor

MCompressor by MeldaProduction is a flexible freeware compressor with one feature I haven’t seen in any other free plugin: a freely drawable compression curve. Most compressors let you set a threshold and a ratio, which together define a fixed compression slope. MCompressor lets you draw the entire transfer curve by hand, which means you can build response shapes that mimic upward compression, expansion, soft saturation, and combinations of all three in a single plugin.

It’s an unusual feature for a free tool, and it opens up sound design possibilities most other compressors can’t reach. MCompressor also offers standard linear, hard, and soft knee modes, an external sidechain input, threshold, ratio, attack, and release controls, plus an oversampling option for cleaner output. The interface has multiple color schemes, a built-in preset manager, and detailed metering with both peak and RMS readings.

One thing to keep in mind before you download it is that MeldaProduction uses an all-in-one installer that ships every plugin in their catalog. You can deselect what you don’t want, but the default download is around 250 MB and includes dozens of additional freeware plugins like MAutoPitch and MCharmVerb. If you only want MCompressor, that’s a lot of extra plugins to install or skip past.
