Apparatus Including Microphone Arrangements
First Claim
1. An apparatus including:
- first and second microphone arrangements, arranged to output first and second signals respectively;
an audio output;
a controller arranged to generate an output signal;
wherein the apparatus is operable in a first mode and a second mode; and
the controller is arranged to;
generate the output signal based on the second signal and a third signal, where the second signal is used to compensate for ambient noise in the environment of the apparatus, and forward the output signal to the audio output when the apparatus is operated in the first mode; and
generate an output signal based on the first and second signals when the apparatus is operated in the second mode.

Abstract
An apparatus includes first and second microphone arrangements, arranged to output first and second signals respectively and is operable in a first mode and a second mode. In the first mode, an output signal is generated based on the second signal and a third signal, where the second signal and, optionally, the first signal, can be used to compensate for ambient noise, for example, for noise cancellation when a telephone call is relayed through a speaker. In the second mode, an output signal is generated based on the first and second signals. In this manner, the combination of the first and second microphone arrangements provides a directional sensitivity that can pick up sound from a remote source, for example, in an audio or video recording session. The apparatus may include a sensor to allow automatic switching between one or more of modes, directional sensitivity patterns and types of recording session.

15. A method comprising:
-
operating an apparatus having first and second microphones, arranged to output first and second signals respectively, in first and second operational modes; when the apparatus is operated in a first mode, generating an output signal based on the second signal and a third signal, where the second signal is used to compensate for ambient noise in the environment of the apparatus, and forwarding the output signal to the audio output; and when the apparatus is operated in the second mode, generating an output signal based on the first and second signals. - View Dependent Claims (16, 17, 18, 19, 20)
