Abstract: Techniques for analyzing a musical performance of a sequence of events. The events have parameters, such as timing, pitch and dynamics. A processor inputs (1-2) the performance; accesses (1-4) a standard performance of the musical piece; identifies (1-6) and compares (1-8) mutually corresponding events and determines (1-10) one of a set of classes: correct”, “low” or “high”. A current marker is displayed on an area of a display. The marker's position depends on the classification and the position of the previous marker, whereby trends and changes in performance accuracy are easily detected during performance.

At least one media tag is determined on the basis of obtained context recognition data formed prior to and after a time point of capturing of the media content. Determined at least one media tag is associated with said media content.

Abstract: A method of generating audio for a text-only application comprises the steps of adding tag to an input text, said tag is usable for adding sound effect to the generated audio; processing the tag to form instructions for generating the audio; generating audio with said effect based on the instructions, while the text being presented. The present invention adds entertainment value to text applications and provides very compact format compared to conventional multimedia as well as uses entertainment sound to make text-only applications such as SMS and email more fun and entertaining.

Abstract: This invention describes a method for adjusting the loudness and the spectral content of digital audio signals in a real-time using warped spectral filtering. A warped processing module modifies a spectral content of a digital audio signal with a set of gains for a plurality of non-linearly-scaled frequency bands determined by a warping factor ? of a warped delay line. Warped delay line signals, generated by the warped delay line, are processed by a warped filter block containing multiple warped finite impulse response filters, e.g., Mth band filters, using individual warped spectral filtering in said plurality of the non-linearly-scaled frequency bands, which is followed by a conventional processing by a dynamic range control/equalization block. The present invention describes another innovation, that is embedding the warped processing module in a two-channel quadrature mirror filter (QMF) bank for improving processing efficiency at high sample rates.

Abstract: Aspects of the invention provide methods, computer-readable media, and apparatuses for spatially manipulating sound that is played back to a listener over a set of output transducers, e.g., headphones. The listener can direct spatial attention to focus on a portion of an audio scene, analogous to a magnifying glass being used to pick out details in a picture. An input multi-channel audio signal that is generated by audio sources is obtained, and directional information is determined for each of the audio sources. The user provides a desired direction of spatial attention so that audio processing can focus on the desired direction and render a corresponding multi-channel audio signal to the user. A region of an audio scene is expanded around the desired direction while the audio scene is compressed in another portion of the audio scene.

Abstract: A method and a system is offered to enable communicating a status of a user (320, 322, 324) to another user. The system uses avatars (350, 352, 354) to display status information, and the avatar moves (350, 354) according to a gesture recorded by the sending user. The recording of the gesture may be done e.g. with the help of motion sensors.

Abstract: A hand-held electronic device for producing stereo effect sound in both a first and a second orientation of the device. The first and second directions are perpendicular to each other.

Abstract: Aspects of the invention provide methods, computer-readable media, and apparatuses for digital processing of acoustic signals to create a reproduction of a natural or an artificial spatial sound environment. An aspect of the invention supports spatial audio processing such as extracting a center channel in up-mixing stereo sound for multi-channel loudspeaker setup or headphone virtualization. An aspect of the invention also supports directional listening in which sound sources in a desired direction may be amplified or attenuated. Direction and diffuseness parameters for regions of input channels are determined and an extracted channel is extracted from the input channels according to the direction and diffuseness parameters. A gain estimate is estimated for each signal component being fed into the extracted channel and an extracted channel may be synthesized from a base signal and the gain estimate. The input channels may be partitioned into a plurality of time-frequency regions.

Abstract: The invention relates to a method, a system, a module, an electronic device and to a computer program product for widening a two-channel input.
