FAC Maxima is an audio effect designed to provide automatic gain control of your audio materials to ensure that the levels stay consistent and never exceed 0dB. It's a clever combination of dynamic processors that can be set to provide a gentle transparent signal boost respecting the initial dynamic or significant colorised level maximisation. Thanks to a unique signal path, algorithms and a small set of parameters, FAC Maxima makes a complicated task easy. In addition to the classic final stage application, FAC Maxima excels on individual tracks too. With a few changes it's easy to go from the common gain deviation compensation, e.g. for vocals, to drastical audio changes that will bring your audio material to new territories: boost reverb tails, flattenize drums… The applications are various and the possibilities are limitless. • Get the final touch! FAC Maxima definitely makes audio louder and that makes it an effective tool in many mastering engineers’ arsenals. • Be creative! Emphasis subtitle details, sometimes floor contains treasure, you will have a completely new listen to your old tracks! The audio background may indeed contain noise, but sometimes also "pearls" that may be revealed. • Go further! Tired by the advertisement boost, or important speech level variation in broadcasting? Use FAC Maxima to maintain the level constant. DJ's may also benefit from the effects to normalise in real time the level of the mixed tracks. As with all FAC products the interface has a unique sober look and provides a great user experience. FAC Maxima also brings a real-time multi-waveform graph having a 6s buffer of the audio material before and after operations, this will help on setting the right parameters and have a visual feedback.

LevLr2 Dynamics Processor Plugin (AUv3) LevLr2 is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. To configure audio settings in standalone mode, tap the Settings button. Please note that the input will be muted by default to avoid nasty feedback! Overview The LevLr2 "leveller" is a dual stage compression and limiting processor with optional clipping stage. I created LevLr2 after receiving messages from people who really liked the simplicity of LevLr, but wanted a bit more control over its internal workings. LevLr2 combines two dynamics processors and has options to select ratios for both compression and limiting, and adds "parallel compression" plus hard and soft clipping functions. While LevLr2 isn't intended to replace your favourite mastering signal chain, it's relatively much lighter on CPU and adds virtually zero latency, so is also suitable for live use. The super fast attack times under the hood also makes LevLr2 great on drums, especially when using parallel compression. For a super-simple lightweight "mastering suite" you could partner LevLr2 with SimplEQ. LOOK AFTER YOUR EARS / SPEAKERS! LevLr2 can make things VERY LOUD, so please be careful with extreme / high values or when using the Randomize function! Controls Active - Toggles the effect On or Off. You can use this control to A/B your settings with the original signal and this will fade gradually between the two with no distracting pops or clicks! Comp - Activates the compressor stage by selecting a compression ratio. Typically lower values are more subtle. In - Determines how hard you drive the compressor. You can also think of this as the compressor threshold, so for example, at 6dB on the In slider, the threshold of the compressor will be -6dB. The compressor also applies makeup gain automatically based on restoring a 0dB level signal after it has been compressed. Mix - Sets the balance between the incoming and compressed audio. At zero, this will be the same as if the compressor was bypassed, and at 100% is the compressed signal only. A good parallel compression effect can be achieved by setting the Comp ratio and In high and the Mix to around 50%. Limit - Activates the limiter stage by selecting a limiter ratio. Typically lower values are more subtle and the highest value is close to "brick wall" limiting. In - Determines how hard you drive the limiter. You can also think of this as the limiter threshold, so for example, at 3dB on the In slider, the threshold of the limiter will be -3dB. The limiter also applies makeup gain automatically based on restoring a 0dB level signal after it has been limited. Clip - Adds an optional Soft or Hard clipper after compression and limiting. The clipping will be more noticeable once you've applied some compression and limiting and depending on the settings, can add subtle warmth to aggressive crunch! Out - Applies a final stage gain trim to the output at the very end of the internal signal chain. In theory, the LevLr2 output should never exceed 0dB, but if you're driving levels really hard, you may want to back this off to around -0.2dB to avoid inter-sample peaks (ISPs) further downstream when recording or mixing-down for example.
