Abstract
Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.
