Master Thesis Intern - Unified Psychoacoustic Model for Speech and Audio Coding 6 Monate Praktikum in Nürnberg


About Dolby

Dolby Laboratories is the global leader in technologies that are essential elements in the best entertainment experiences. Founded in 1965 and best known for high-quality audio and surround sound, Dolby innovations enrich entertainment at the movies, at home, or on the go.


In the sound coding community there is a trend towards bringing together the previously separated worlds of general audio coding (e.g., AAC) and speech coding (e.g., AMR-WB). It does so by integrating elements from audio coding and speech coding into a single unified system so that the combined codec is highly efficient (in terms of compression) for all content types. Typically speech and audio codecs have their own well-tuned psychoacoustic model (i.e., model for human hearing) for shaping the quantization noise. However, the two psychoacoustic models may be merged or derived from one another so that the transmitted side-info is minimized. In this project we plan to investigate and compare the parameters describing the masking curves for the speech and audio codecs concerning their redundancy and inter-changeability; then aim to learn and derive a relation between them.

This project is for Master’s Thesis students in Electrical Engineering, Computer Science, Physics, and Mathematics.
