Can I have the mic? Exploring the quality of smartphone microphones for audio signal processing

In this master topic we want to explore several different hardware setups and how they possible can influence the process of audio signal processing.
Master

Audio processing is a very hot topic in machine learning. Nevertheless, using mobile devices to collect audio comes with some challenges. For example, the quality of the microphone, the compression used, etc.
In this master topic we want to explore several different hardware setups and how they possible can influence the process of audio signal processing.

Goal

A comparison of different smartphones and their audio recording abilities. A study about how the different qualities can influence the outcome of audio signal processing and a possible solution to overcome the problems occurring with bad and strong compressed audio data

Learning outcome

Hardware and audio codecs understanding, machine learning, audio processing

Qualifications

mathematical skills, programming skills, interested in hardware
