Artificial intelligence, referred to as AI. With the application of artificial intelligence algorithm technology in the imaging field, computer vision technology has shined in recent years, and AI has become the standard configuration of streaming media platforms.

AI is applied a little later in the audio field, but the technological progress is impressive. AI-based speech recognition, speech synthesis, sound source localization, and automatic rendering have all made great breakthroughs.

As an innovative technology company, LEONIS combines immersive audio technology HOLOSOUND with AI technology to achieve extremely shocking technologies including AI-Design, AI-Position, and AI-Render.

1> HS-AI-DESIGN

Combining the immersive audio technology HOLOSOUND and artificial intelligence technology AI, LEONIS Cinema developed the HOLOSOUND AI-Conf Tools, which can realize the automatic layout of HOLOSOUND cinema speakers.  You only need to enter the details of the cinema hall (including screen size, length and width of the hall, etc.), speakers' brand and amplifiers brand, and everything is done automatically.

Compared to the implementation of Dolby ATMOS, HOLOSOUND AI-Conf Tools has several advantages:

1.AI intelligent algorithm can better meet actual needs

2. Engineered Management

3. User can customize speaker and amplifier database

2> HS-AI-POSITION

Based on the human hearing system mechanism, HS-AI-Position can realize the automatic localization of point sound sources with accuracy within +/- 1 degree (azimuth and elevation) by using unique algorithms and models.

Based on LEONIS microphone array and artificial head analyzer, combined with HS-AI-Position, LEONIS proposed the concept of audio immersive index, which evaluate the quality of immersive audio with quantified indicators. It overcomes the shortcomings of strong subjectivity of traditional audio evaluation methods and, and makes audio evaluation simpler and the evaluation results more accurate. Audio Immersion Index AII fills the global gaps in audio evaluation methods, and can be used to compare immersive audio with non-immersive audio, as well as compare various types of immersive audio.

3> HS-AI-RENDER

By using artificial intelligence technology, HS-AI-Render can automatically render audio into the sound scene that is automatically laid out by HS-AI-Design, and let the sound surround the audience to restore the true soundscape. It can output up to 256 channels. Related products include: immersive audio processor DCAP-IA, immersive audio processor DCAP-OBIA, enhanced immersive audio processor DCAP-OBIA-E, etc.
