Methods, systems, and storage media are described for providing codec mode notification (CMN) messages for speech to be signaled from a sender to a receiver. Other embodiments may be described and/or claimed.

Signaling codec mode notifications for multimedia telephony sessions

Apparatuses of user equipment (UEs) for end-to-end coordination of voice over cellular data network communications. An apparatus of a UE includes one or more data storage devices and one or more processors. The one or more data storage devices are configured to store delay budget information pertaining to end-to-end delivery of a real-time transport protocol (RTP) stream sent from a remote UE to the UE. The one or more processors are configured to generate an application layer message including the delay budget information, the application layer message to be transmitted to the remote UE to enable the remote UE to request, from a cellular base station servicing the remote UE, additional air interface delay based on the delay budget information.

Apparatuses for end-to-end coordination of voice over cellular data network communications

Systems, apparatuses, methods, and computer-readable media are provided for negotiating Radio Access Network (RAN)-level capabilities toward improving end-to-end quality of Internet Protocol Multimedia Subsystem (IMS) communication sessions, such as Voice over Long-Term Evolution (VoLTE) calls. Disclosed embodiments include Session Description Protocol-based mechanisms to signal the RAN-level capabilities. The RAN-level capabilities may include, for example, delay budget information signaling, Transmission Time Interval bundling, RAN frame aggregation, RAN-assisted codec adaptation or access network bitrate recommendation, and/or other like capabilities. Other embodiments may be described and/or claimed.

Session description protocol mechanisms for signaling radio access network capabilities in multimedia telephony sessions

An audio processing device includes a first microphone configured to receive a first signal a second microphone configured to receive a second signal, a noise reduction gain determination circuit configured to determine a noise reduction gain based on the first signal and the second signal, a noise reduction circuit configured to attenuate the first signal based on the determined noise reduction gain, and an output circuit configured to output the attenuated signal.

Audio processing circuit and method for reducing noise in an audio signal

Wind noise reduction is described for audio signals received in a device. In one embodiment, an audio signal is decomposed into a plurality of sub-bands, the audio signal including wind noise, a first sub-band of the plurality of sub-bands low-pass filtered, wind noise is removed from the first sub band and the first sub-band is combined with the other sub-bands after removing wind noise.
