What ALT-436C does
The plugin reproduces the sound of a classic tube compressor from the late 1950s and is presented as the relic that shaped Beatles-era recordings. Gain reduction reaches up to 30 dB without thump, keeps the reproduced level uniform, preserves dynamic range and avoids overmodulation.
Antelope Audio presents it as useful on bass guitars and vocals, where it is said to make them stand out in a mix, and on the mix bus, where it adds a measure of glue.
Key features
