Title: Innovations of Jens Popp in Audio Processing
Introduction
Jens Popp is a notable inventor based in Nuremberg, Germany, recognized for his contributions to audio processing technologies. With a total of 10 patents to his name, Popp has made significant advancements in the field of audio decoding and encoding.
Latest Patents
One of his latest patents is a method, apparatus, and systems for audio decoding and encoding. This innovative audio processing system accepts an audio bitstream with various predefined audio frame rates. It includes a front-end component that receives a variable number of quantized spectral components corresponding to one audio frame and performs inverse quantization based on predetermined, frequency-dependent quantization levels. The system is designed to be agnostic of the audio frame rate, allowing for flexibility in audio processing. Additionally, the system features a frequency-domain processing stage and a sample rate converter, which together provide a reconstructed audio signal sampled at a target frequency independent of the audio frame rate. This adaptability enables the system to operate frame-synchronously alongside video processing systems that accept multiple video frame rates.
Another significant patent involves a main-associated audio experience with efficient ducking gain application. In this innovation, an audio bitstream is decoded into audio objects and metadata. The audio metadata specifies frame-level gains for different audio frames. Based on these gains, the system determines whether to generate sub-frame gains for specific audio objects. A ramp length is established for generating these sub-frame gains, which are then used to render a sound field represented by the audio objects through speakers.
Career Highlights
Throughout his career, Jens Popp has worked with prominent companies in the audio industry, including Dolby International Ab and Dolby Laboratories Licensing Corporation. His work has significantly influenced the development of audio technologies and processing systems.
