{"product_id":"waves-l4ultr","title":"Waves L4ULTR L4 Ultramaximizer Mastering Peak Limiter Plugin","description":"\u003cp\u003eThe Waves L4 Ultramaximizer is built for mastering engineers and mixing professionals who need compliant, competitive loudness without sacrificing punch, low-end energy, or perceived dynamics. It fits directly into DAW-based mastering sessions, broadcast post-production workflows, and streaming delivery pipelines where True Peak compliance is non-negotiable. Whether you are finalizing an album master, preparing a podcast for distribution, or delivering stems for a broadcast mix, the L4 handles loudness maximization at a professional level.\u003c\/p\u003e\u003cp\u003eWhat sets the L4 apart from earlier Ultramaximizer generations and competing brickwall limiters is its adaptive clipping and release technology. Rather than applying a fixed release curve, the processor analyzes incoming signal content and adjusts release behavior independently for transients, sustained tones, and low-frequency material. The result is a limiter that maintains punch and weight even at high gain reduction settings. True Peak metering addresses the inter-sample clipping that conventional peak metering misses, keeping output compliant with EBU R128, ATSC A\/85, Spotify, Apple Music, and YouTube specifications. Integrated LUFS metering removes the need for a separate loudness meter, consolidating the mastering signal chain and reducing plugin overhead in the session.\u003c\/p\u003e\u003cp\u003eThe L4 runs natively on macOS and Windows in VST, VST3, AU, and AAX formats, and extends to SoundGrid-enabled hardware for live and post-production environments where low-latency processing is required. Activation is handled through Waves Central, keeping license management centralized and portable across studio workstations.\u003c\/p\u003e","brand":"WAVES INC","offers":[{"title":"Default Title","offer_id":53820564177080,"sku":"207927","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/207927_WAVES-L4ULTR-L4-ULTRAMAXIMIZER_ALT01sqr.jpg?v=1785341129","url":"https:\/\/soundpro.com\/products\/waves-l4ultr","provider":"SoundPro","version":"1.0","type":"link"}
