• an auxiliary device;
• a processor that:
• receives an audio signal comprising audio information;
• receives auxiliary information from the auxiliary device;
• determines, based on the audio information and the auxiliary information, a type of audio environment in which the electronic device is operating;
• and
• selects an audio pre-processing procedure from a plurality of pre-defined audio pre-processing procedures based on the determined audio environment type;
• and
• an audio pre-processor module that carries out the selected audio pre-processing procedure on the audio signal to generate a pre-processed audio signal.
