Title: Antonio Mario Alvarez-Tinoco: Innovator in Audio Technology
Introduction
Antonio Mario Alvarez-Tinoco is a distinguished inventor based in Singapore, known for his significant contributions to audio technology. With a total of 8 patents to his name, he has made remarkable advancements in the field of digital audio encoding.
Latest Patents
Among his latest patents is the "Multi-precision technique for digital audio encoder - AC-3." This high-quality audio compression format is widely utilized in feature films and on Digital Versatile Disks (DVD). The algorithm is typically embedded in the firmware of a DSP Processor, which may only support fixed-point arithmetic due to cost constraints. It is commonly believed that 16-bit processing cannot deliver the high fidelity audio expected from AC-3 technology. However, Alvarez-Tinoco's work demonstrates that double precision computation can be effectively employed on such processors, allowing for high-quality audio without overwhelming the processor's capacity for real-time operation. His extensive simulation studies reveal that the quality of the encoder on a 16-bit processor closely matches that of a single precision 24-bit implementation, all while maintaining manageable computational complexity.
Another notable patent is the "Aliasing cancellation in audio effects algorithms." This method addresses aliasing cancellation in audio effects algorithms by utilizing a delay modulated signal derived from the interpolation of a delay modulator at an instantaneous sampling frequency. The process involves determining the instantaneous sampling frequency and band limiting an input signal prior to interpolation, ensuring high-quality audio effects.
