AI Technical Summary

Problems solved by technology

Since users often change the position of the phone (especially during long conversations), any attempt to use high-gain narrow-beam processing may result in the beam not being directed at the mouth and producing less than low-gain or standard full-beam processing. Signal to Noise Ratio for Microphone Profiles

Abstract

An apparatus comprising at least one processor and at least one memory comprising computer program code, the at least one memory and computer program code being itself direct to, with the at least oneprocessor, cause the apparatus to perform at least the following: determine a change in position of the apparatus; and processing the at least one audio signal according to the position change.

Description

[0001] This application is a divisional application of the patent application with the application number 200980163257.6 and the title of the invention "a device" submitted on November 24, 2009. technical field [0002] The invention relates to devices for processing audio signals. The invention also relates, but is not limited to, to apparatus for processing audio and voice signals in audio devices. Background technique [0003] In telecommunications equipment, a microphone or array of microphones is often used to capture sound waves and output them as electrical signals representing audio or speech, which can then be processed and sent to other devices or stored for later retrieval. put. Current technology allows the use of more than one microphone within a microphone array to capture sound waves, and the resulting audio signal from each microphone can be passed to an audio processor to help isolate the desired sound waves. An audio processor may, for example, determine ...
