Source Intelligence: L-Acoustics Introduces Vocal Isolation for Live Performances

L-Acoustics has unveiled Source Intelligence, a new feature designed to isolate vocal performances and reduce bleed during live events. This innovative tool leverages machine learning to filter out unwanted audio sources such as instruments, crowd noise, or monitor feedback while preserving the singer’s voice.

The algorithm continuously identifies the voice signal within the microphone, distinguishing it from other audio inputs. By removing up to 40 dB of extraneous sound, Source Intelligence minimizes the risk of feedback and enhances the clarity of vocal performances.

“For years, engineers have struggled with managing bleed and feedback through various techniques like notch filters or expanding systems,” explains Ryan John, Director of Product Management at L-Acoustics. “Source Intelligence offers a more straightforward solution by continuously learning from the voice signal, allowing for real-time adjustments without compromising the overall mix.”

This advancement in vocal isolation is particularly beneficial for live performances where maintaining clear audio is crucial. Engineers can now focus on enhancing the vocal performance rather than constantly managing feedback issues.

“Source Intelligence delivers a vocal experience that rivals studio-quality recordings,” remarks Joey Diehl, FOH engineer for Benson Boone. “It’s transformed how we handle live performances by providing cleaner audio without the need to adjust settings manually.”

“I was able to capture crisp and clean vocals in even noisy environments like a Broadway production,” Cody Spencer adds, referencing his work on Tony Award-winning show Dog Day Afternoon. “Source Intelligence has significantly improved our ability to deliver high-quality sound.”

Currently available within the L-Acoustics L-ISA Processor II, Source Intelligence integrates seamlessly into their existing workflow. This feature is expected to revolutionize how live events are produced and enjoyed.
