Celine Dion Uses AI for Voice Clarity

During Celine Dion's concerts in Paris, a French artificial intelligence developed by L-Acoustics is used to enhance the clarity of her voice. This technology, known as Source Intelligence, is designed to transform the sound of performances without replacing the engineers working behind the scenes.

AI Analyzes and Filters Sound

The system uses machine learning to analyze the signal captured by the singer's microphone, distinguishing her voice from surrounding sounds such as instruments, crowd noises, echoes, or music coming from the speakers. According to L-Acoustics, the technology can reduce non-vocal sounds by up to 40 decibels with a latency of less than 8.5 milliseconds.

Improving Audience Experience

For her Paris residency, Celine Dion benefits from this technology, which is used to make her voice more intelligible to the audience. The system also reduces the risk of feedback. Denis Savage, Celine Dion's sound engineer for 38 years, describes the technology as almost magical, noting that its primary objective is to keep the artist's voice perfectly audible regardless of the musical arrangements or movements on stage.

L1 Speakers Enhance Sound Control

In addition to Source Intelligence, L-Acoustics has installed its L1 speakers for the Paris concerts, arranged to better control the sound propagation in the hall. According to the engineers interviewed, this configuration allows maintaining a sound level on stage up to 26 decibels lower than that of the public area.

Investment in Advanced Technology

The entire audiovisual and acoustic system represents an investment exceeding one million euros. L-Acoustics, founded in 1984 by Christian Heil, has established itself as a reference in professional sound. The company assembles its speakers in Marcoussis, south of Paris, and employs about 1,100 people.

Future Revenue Projections

It plans to reach 400 million euros in revenue in 2027, according to the company's projections. With Source Intelligence, the manufacturer adds a new software dimension to its historical activity. The technology works exclusively with its L-ISA Processor II processor and its professional audio systems.

Integration Within L-Acoustics Ecosystem

This choice reinforces the integration of its equipment but also requires customers to remain within its ecosystem. Other artists, including Harry Styles, Bruno Mars, The Weeknd, and Rosalía, have also used this technology on stage. Laurent Vaissié, co-general director of L-Acoustics, assures that the goal is not to replace sound engineers.

Automation with Human Oversight

The software automates certain corrections but leaves artistic decisions and mixing work to professionals.
