TBProAudio ABLM2 v2.1.13 VST VST3 AU AAX [WIN & macOS]

ABLM is a gain control which enables level matched and sample accurate AB comparison of FX chains.

We at TBProAudio found us very often in mixing or mastering situations where we need to quickly identify the contribution of a certain plugin (FX) or even a complex FX chain to the sound.

Most DAWs can easily enable/disable (AB) single plug-in or even whole FX chains, but in most case there is an audible loudness difference between both cases. In order to compare the impact of a plugin chain objectively the loudness of the incoming signal should match with the loudness of outgoing signal.

Comparing the plugin effect at equal loudness levels avoids the “louder is better” – pitfall.
