MULTI-BAND DUCKING OF AUDIO SIGNALS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240304196 titled 'MULTI-BAND DUCKING OF AUDIO SIGNALS
The abstract describes a method for multi-band ducking of audio signals, involving receiving a downmixed audio signal, separating it into frequency bands, determining ducking gains for each band, and generating a broadband decorrelated audio signal with the ducking gains applied.
- Receiving a downmixed audio signal at a decoder
- Separating the input audio signal into a first set of frequency bands
- Determining ducking gains for each frequency band
- Generating a broadband decorrelated audio signal with ducking gains applied to frequency bands before and after generation
Potential Applications: - Audio production and mixing - Sound engineering for film and television - Live sound reinforcement - Music production and mastering
Problems Solved: - Improving audio quality by reducing interference between different frequency bands - Enhancing the clarity and separation of audio elements in a mix - Providing dynamic control over the volume levels of different frequency ranges
Benefits: - Enhanced audio quality and clarity - Improved control over audio dynamics - Greater flexibility in audio mixing and production
Commercial Applications: Title: "Advanced Audio Ducking Technology for Enhanced Sound Mixing" This technology can be used in professional audio production studios, film post-production facilities, live sound venues, and music recording studios. It can be integrated into audio software plugins, hardware processors, and mixing consoles to provide advanced ducking capabilities for audio engineers and producers.
