The present invention provides a method for processing music audio data, comprising the steps of providing input audio data representing a first piece of music containing a mixture of predetermined musical timbres, decomposing the input audio data to generate at least a first audio track representing a first musical timbre selected from the predetermined musical timbres, and a second audio track representing a second musical timbre selected from the predetermined musical timbres, applying a predetermined first audio effect to the first audio track, applying no audio effect or a predetermined second audio effect, which is different from the first audio effect, to the second audio track, and obtaining recombined audio data by recombining the first audio track with the second audio track.

Provided are a disk device and a parameter setting method for the disk device. The disk device includes a control object, a controller that controls the operation of the control object, a loop shaping filter that is connected in parallel to the controller, determines a parameter for suppressing a rotational asynchronous disturbance using a transfer function from an output thereof to an input of the rotational asynchronous disturbance acting on the control object, and a notch filter that suppresses resonance of a head. In a case where the control object is changed due to manufacturing fluctuations and the like, the loop shaping filter is redesigned while reflecting a change in the transfer function, while the parameter of the notch filter is changed in accordance with the change. Thus, even in a case where the characteristics of an actuator as the control object differ from those at the time of design, the NRRO disturbance can be suppressed as intended, and the positioning accuracy of the head can be improved.

The invention is entitled "Method and system for seamless media synchronization and switching." A method performed by a portable media player device is disclosed. The method receives a microphone signal that includes audio content output by an audio playback device via a loudspeaker. The method determines identifying information about the audio content, where the identifying information is determined through acoustic signal analysis of the microphone signal. In response to determining that the audio playback device has ceased outputting the audio content, the method retrieves an audio signal corresponding to the audio content from a local memory of the portable media player device or a remote device communicatively coupled thereto, and uses the audio signal to drive a speaker that is not part of the audio playback device to continue outputting the audio content and any additional audio content related to the audio content.

Disclosed is an audio recording and conversion method for a Bluetooth headset, which specifically relates to the field of audio recording and conversion. In the present disclosure, a Bluetooth function of an audio source device is enabled to pair the audio source device with a Bluetooth headset. Subsequently, recording is initiated by tapping a "record" button on the headset, and the system guides a user to select an audio format and confirm recording settings. During the recording process, a built-in microphone of the headset acquires an audio signal in real time, and the acquired audio signal is subjected to denoising and signal amplification. The processed audio signal is then converted into a digital signal. A watermark is embedded into the processed digital signal, and a watermark assessment value is calculated. Whether the watermark has been embedded is verified by performing comparison on the basis of the watermark assessment value. The digital signal is then converted into an analog signal to reconstruct an audio signal. Finally, the system performs watermark detection on the reconstructed audio signal. Comparison is performed on the basis of the detected watermark information to ensure integrity and authenticity of the audio signal data.

Systems and methods monitor copyrighted material and the proportion of a document accessed. A library of material in which copyright or related rights subsist is linked to copyright data for each item of material. A database contains rules for use of copyrighted material. The extent of a document in its entirety, including copyrighted material, can be quantified e.g. by an input counter counting its text, graphics and other content. The extent of a document accessed in each instance of use of the document can be quantified e.g. by an output counter. Use of copyrighted material can be metered based on the accessed extent. Document access can be permitted e.g. based on copyright use rules. A determination can be made as to whether the proportion of a document accessed is above a predetermined value. If fair use is unavailable or exhausted, a user may purchase a licence to access copyrighted material.

This invention belongs to the field of audio signal processing and privacy protection technology, specifically relating to an adaptive ultrasonic anti-recording interference method based on local AI voice feature analysis. The method involves: acquiring environmental audio signals through an audio acquisition module; performing voice feature analysis on the pre-processed audio signals; establishing a dual-microcontroller collaborative working mode; controlling the ultrasonic emission module to generate and drive the ultrasonic transducer array to emit ultrasonic interference signals; the second microcontroller dynamically adjusting interference parameters based on a closed-loop feedback compensation mechanism; and a power management module switching system power consumption modes according to the voice detection status to achieve multi-mode power management. This invention relies on a local lightweight AI model to complete voice feature extraction, achieving real-time voice detection and interference parameter generation without relying on a network. This eliminates network latency and avoids the privacy leakage risks of uploading audio data to the cloud, making it suitable for offline use scenarios of portable devices.
