Naturl Audio AL-1 v1.0.2 U2B macOS

Introducing the AL-1 Premium mastering limiter for natural, musical loudness.

Loudness with a minimal footprint. The AL-1 is a premium limiter built on a new approach to peak control — designed to stay musical, stay intact, and hold up under pressure. Validated through thousands of hours of blind testing and real-world feedback, the AL-1 is for those who demand tools that respond musically, not mechanically.

Zero Look-Ahead Design
The AL-1 abandons traditional look-ahead limiting in favor of an original circuit that keeps limiting minimally invasive. Experience more weight and articulation, a truer form of your material — processed with extremely low-latency.

Non-Brickwall Limiting
The AL-1 avoids a clipping or wave-shaping stage typically used to force a hard ceiling resulting in a more natural and open sound — preserving dynamics, detail, and dimension.

Intuitive Workflow
The AL-1's left-to-right workflow streamlines the decision making process. The result is a limiter that offers power while remaining quick to dial in, letting you focus on your music instead of the plugin.

FEATURES
Mode.
The AL-1's engine and unique envelope follower provide the AL-1 with a wide range of dynamic behaviors. Experience an honesty that translates your true sonic intentions to the listener.

Window.
The AL-1 utilizes a new strategy to retroactively reshape samples around peaks for greater fidelity under pressure. Retain more low end and transients keeping attacks clear and releases natural.

Linking.
The AL-1's correlation-based stereo linking keeps the center defined without sacrificing your image. Maintain dimension, impact, and emotional connection.

Optimizer.
The AL-1's optimizer section allows for a musical lift to low level content with upwards compression and intelligent release based makeup – adding loudness without coloration.

Metering.
Professional-grade metering at your fingertips. Precisely monitor your output with LUFS, VU, and Peak meters — giving you the insight needed to meet loudness standards and maintain dynamic integrity.
