Enhanced stereophonic audio recordings in handheld devices

摘要

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.

主权项

1. A system for enhanced stereophonic audio, comprising:
an electronic device comprising one or more circuits and a first microphone and a second microphone, the one or more circuits are for: assessing stereophonic recording performance in the electronic device using the first microphone and the second microphone; and configuring processing of signals generated by the first microphone and the second microphone, based on the assessed stereophonic recording performance, wherein the configuring comprises adaptively modifying the processing to enhance stereophonic recording performance, to match a stereophonic recording performance obtained by-at least one out of (a) increasing a spacing between the first and second microphones to a desired distance between the first and second microphones, the desired distance exceeds a current distance between the first and second microphones, and (b) increasing a directional reception characteristic of at least one of the first and second microphones.
