AUDIO REPRODUCTION DEVICE, AUDIO REPRODUCTION LSI, AND AUDIO REPRODUCTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240040311 titled 'AUDIO REPRODUCTION DEVICE, AUDIO REPRODUCTION LSI, AND AUDIO REPRODUCTION METHOD
Simplified Explanation
The abstract describes an audio reproduction device that can change the frequency or sound volume of audio during playback in stages. It includes a reproduction control part, a pitch register, a volume register, and a fading register. The reproduction control part adjusts the frequency or sound volume in stages based on the step setting value stored in the fading register, in response to changes in the pitch or volume setting values stored in the pitch and volume registers.
- The device can change the frequency of audio in stages or the sound volume in stages during playback.
- It includes registers to store pitch setting values, volume setting values, and step setting values.
- The reproduction control part adjusts the frequency or sound volume based on the step setting value, in response to changes in the pitch or volume setting values.
- The pitch or volume setting value after change is used as the target value for the adjustment.
Potential applications of this technology:
- Audio editing software: This technology can be used in audio editing software to provide users with the ability to fade in/out or change the pitch of audio in stages.
- Music production: It can be used in music production to create dynamic and gradual changes in pitch or volume during playback.
- Sound effects generation: This technology can be utilized in sound effects generation to create realistic and immersive audio experiences.
Problems solved by this technology:
- Limited control over pitch and volume changes: This technology allows for precise and gradual changes in pitch and volume, providing more control and flexibility in audio reproduction.
- Smooth transitions: The ability to change the frequency or sound volume in stages helps to create smooth and seamless transitions in audio playback.
- Enhanced user experience: This technology enhances the user experience by allowing for customized and dynamic audio playback.
Benefits of this technology:
- Versatility: The device can be used for various applications, including audio editing, music production, and sound effects generation.
- Precise control: Users can make precise adjustments to the pitch and volume of audio in stages, allowing for more creative possibilities.
- Seamless transitions: The technology ensures smooth transitions between different pitch or volume settings, resulting in a more natural and immersive audio experience.
Original Abstract Submitted
an audio reproduction device includes a reproduction control part executing pitch fading processing of changing a frequency of audio during reproduction in stages or volume fading processing of changing a sound volume in stages, a pitch register storing a pitch setting value, a volume register storing a volume setting value, and a fading register storing a step setting value indicating a form of change in the pitch or volume fading processing. the reproduction control part changes the frequency in stages in a form based on the step setting value in response to change of the pitch setting value while having a pitch setting value after change as a target value, and changes the sound volume in stages in a form based on the step setting value in response to change of the volume setting value while having a volume setting value after change as a target value.
