Real-time voice separation technology running on the L-ISA Processor II eliminates PA bleed, stage noise, and feedback risk without compromising quality or clarity<\/em> <\/em><\/p>\n\n\n\n

\n\n\n\n

LOS ANGELES, CA \u2013 May 2026 \u2013 <\/strong>L-Acoustics today announces Source Intelligence, a proprietary voice-separation technology that delivers clearer, more intelligible vocals and unprecedented gain before feedback for live performances. Running as an exclusive licensed application on the L-ISA Processor II and fully integrated in the L-Acoustics system workflow, Source Intelligence gives front-of-house engineers mixing on an L-Acoustics PA a groundbreaking tool to clean up vocals from noisy stages and allow performers to move freely across any stage configuration, including in front of the PA, without risking feedback or sacrificing vocal clarity. <\/p>\n\n\n\n

The technology launched at the L-Acoustics Keynote 2026 alongside the L1 large-format line array system and CS1 subwoofer. The event featured a performance by The War on Drugs. <\/p>\n\n\n\n

The Voice, and Nothing But the Voice<\/strong> 
Source Intelligence uses machine learning to do something not previously possible in live sound: continuously identify the voice in a microphone signal and remove everything else. PA bleed, crowd noise, stage instruments, room reverb\u2026 all of it is stripped away in real time, leaving a cleaner, more natural-sounding vocal without the restrictions that have long been a fact of life on touring productions. The result is a vocal that preserves the natural tone, character, and intelligibility of the source, a quality difference that has consistently been audible to engineers and listeners in blind tests. <\/p>\n\n\n\n

\u201cFor decades, engineers have been solving the PA bleed and feedback problem with compromises like notch filters that color the sound, expanders that can be unpredictable, or staging layouts that pull performers away from the audience,\u201d explains Ryan John, Director of Product Management, Software at L-Acoustics. \u201cSource Intelligence removes that trade-off entirely. The machine is continuously listening and continuously working, so the engineer can focus on the mix instead of fighting feedback, and the performer can own the whole stage.\u201d <\/p>\n\n\n\n

A Measurable Difference<\/strong> 
In blind listening tests with both internal and external participants, Source Intelligence consistently ranked highest for voice quality among competitors, removing up to 40 dB of non-voice signal \u2014 a difference that is immediately and consistently audible to professional engineers and casual listeners. The technology also significantly reduces feedback risk by eliminating the PA bleed and ambient noise that cause it, rather than reacting after it starts. <\/p>\n\n\n\n

From Arena Stages to Houses of Worship<\/strong> 
Source Intelligence has been used in the field since Spring 2025 across major touring productions, Broadway shows, and key house-of-worship campuses. Current beta partners include Solotech on the Harry Styles tour, Clair Global on Benson Boone and Rosalia tours, and PRG on the Broadway production Dog Day Afternoon<\/em>.  <\/p>\n\n\n\n

\u201cSource Intelligence gives me a vocal sound like no other. It\u2019s basically studio quality vocals now, which changes the game completely,\u201d says Joey Diehl, FOH engineer for Benson Boone. <\/p>\n\n\n\n

The technology is designed for any application where a voice is being amplified: touring, house of worship, corporate events, and theatrical productions. It works with handheld, headset, lapel, and distant-pickup microphones, and processes up to four channels simultaneously. Each instance can handle one vocal at a time and can even be placed in the path of a group of channels so that a single instance may, for example, serve all handheld microphones in a corporate workflow. \u201cI\u2019m very impressed with how much headroom it gives me. I was able to get crisp, clean vocals in any scenario \u2014 including very loud stage environments and actors in front of the PA,\u201d says Cody Spencer, Tony Award-winning sound designer who used it on the Broadway production Dog Day Afternoon<\/em>. <\/p>\n\n\n\n

\"Source
Source Intelligence runs exclusively on the L-ISA Processor II, the same platform that powers L-ISA Immersive Hyperreal Sound, L-Acoustics DJ, Ambiance, and HYRISS, with end-to-end latency of less than 8.5 ms over MADI and full PSU, network audio, and DSP redundancy.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n

The L-ISA Processor II: A Growing Ecosystem of Intelligence<\/strong> 
Source Intelligence is part of a growing portfolio of licensed technologies that run on the L-ISA Processor II as part of the full L-Acoustics ecosystem, the same platform that powers L-ISA Immersive Hyperreal Sound, L-Acoustics DJ, Ambiance, and HYRISS. Each of these software applications are separately available for purchase, allowing engineers and production companies to expand the capabilities and flexibility of a processor they already own. <\/p>\n\n\n\n

Once installed, Source Intelligence requires no threshold setting, no ongoing adjustment, and no changes to the existing console workflow or signal routing. End-to-end latency is less than 8.5 ms over MADI, fixed whether processing is active or bypassed, so that automation and snapshot changes never affect system timing. Full PSU, network audio, and DSP redundancy are standard through the L-ISA Processor II platform. <\/p>\n\n\n\n

Availability<\/strong> 
Source Intelligence is available now as a software subscription via L-Acoustics All Access for the L-ISA Processor II, exclusively for L-Acoustics system deployments.  <\/p>\n\n\n\n
