Our verdict on Sound Radix POWAIR
Sound Radix POWAIR is a desktop audio dynamics plug-in for balancing loudness and shaping transients on voices, instruments, and full mixes. It combines K-weighted loudness auto-leveling with an adaptive compressor, while supporting mono, stereo, and mid/side processing. Engineers working on individual tracks or complete mixes can use variable compression linking, Punch control, and loudness metering to manage dynamics and output levels.
POWAIR is sold through one paid plan: POWAIR costs $149 USD as a one-time purchase. A seven-day free trial is available. The plug-in runs on Windows and macOS and is offered in AAX, Audio Unit, VST, and VST3 formats, giving it a place in compatible digital audio workstation setups. Installation and authorization require an iLok account and License Manager, which should be part of the onboarding plan for users who do not already use that system.
Its standout capability is the combination of loudness-aware processing and adaptive dynamics control. Machine-learning-based perceived-loudness auto-makeup gain compensation, tempo-synced recovery, band-pass and band-reject side-chain filters, and an external side-chain input provide detailed control over how compression responds. LKFS and true-peak output metering helps monitor delivery levels. POWAIR is a strong fit for engineers who want a specialized processor for leveling and compression, but those seeking stem separation, auto EQ, or a broader mixing environment should choose a more comprehensive tool.
