Internship - Deep learning-based enhancement of parametric stereo audio compression

Job Description

Project Title: Deep learning-based enhancement of parametric stereo audio compression

Project Duration:  6 months

Background: In parametric stereo coding, a stereo audio signal is downmixed to a mono signal, and stereo parameters are estimated and transmitted to the decoder. At the decoder, the stereo signal is reconstructed using the mono downmix and the transmitted stereo parameters. While performance has been promising, further improvements and evaluations are necessary.

Project Summary: This non-thesis project aims to advance our current work on neural network-based parametric stereo coding. The objective is to improve the quality of the decoded signal while maintaining coding efficiency relative to the baseline signal processing based parametric stereo coder.

Key Tasks and Deliverables:

• Literature Review and Familiarization
• System Performance Verification
• Quantizer Integration and Evaluation
• Latent variable size analysis
• Exploration of Alternate Architectures
• Final Report and Presentation

Required Skills:

• Master’s student in the field of Electrical Engineering\ Computer Engineering with good understanding and enthusiasm for learning about neural networks and deep learning frameworks.
• Proficiency in Python and relevant libraries (PyTorch, Torchaudio).
• Familiarity with audio signal processing/coding concepts (e.g., down/up-mixing, quantization).
• Analytical skills to evaluate different neural network architectures.

Supervision and Support: The student will have access to the necessary computational resources and audio datasets required for the project. Regular meetings will be held to discuss progress, address challenges, and refine approaches.

Project Assessment: The student’s performance will be assessed based on regular progress reports, the final report, the quality of the proposed solutions, and the effectiveness of the implemented modifications.
