Description

Technical Field

[0002] Sleep disorders are a common problem in modern society, and many people seek to improve their sleep quality through various methods. There are already some applications on the market that help users fall asleep by playing white noise, nature sounds or meditation music. In addition, there are light therapy devices that adjust the user's biological clock by flashing light at a specific frequency to promote better sleep.

[0003] However, these applications do not process the audio using a specific 40Hz gamma frequency. Studies have shown that 40Hz gamma frequency oscillations have an important impact on memory, attention, and consciousness. Therefore, audio processing based on a 40Hz gamma frequency has a more significant effect on improving sleep.

[0004] There are some existing devices that use 40Hz gamma frequency, such as sensory stimulation devices for Alzheimer's patients, but these devices are mostly for medical purposes and lack user-generated content and personalized recommendation functions. In addition, existing light therapy devices mainly focus on the frequency and intensity of light, rather than comprehensive sensory stimulation combined with audio and video, which limits their potential in promoting sleep. In addition, existing technologies usually process audio and video separately, lacking an integrated system to coordinate the application of 40Hz gamma frequency for audio and video. Summary of the invention

[0005] The present invention proposes a sleep promotion method and an audio and video system based on a 40 Hz gamma frequency, which solves the problem that the prior art does not fully utilize the audio and video of the 40 Hz gamma frequency to improve sleep quality.

BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 A schematic diagram of the system structure of an embodiment of the present invention;

[0036] Figure 2 The figure is a schematic diagram of a method flow of an embodiment of the present invention. DETAILED DESCRIPTION

[0037] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0038] like Figure 1 As shown, an embodiment of the present invention provides a sleep-promoting audio and video system based on a 40 Hz gamma frequency, including: an audio processing module, a video processing module, a user upload module and a content recommendation module.

[0039] The audio processing module is used to generate an audio file based on a 40Hz gamma frequency to promote sleep. The audio file can be a separate gamma frequency waveform or a mixed audio combined with natural sounds or white noise.

[0040] Specifically, the user first selects an existing audio file, such as white noise or nature sounds, or records new audio.

[0041] The audio processing module uses digital signal processing (DSP) technology to generate audio with a 40Hz gamma frequency, and superimposes the generated 40Hz gamma frequency audio as an independent audio layer on the background audio or natural audio selected by the user, and mixes the 40Hz gamma frequency audio with the audio selected by the user. The overall spectrum of the mixed audio is adjusted to ensure that the superimposed 40Hz gamma frequency is not covered or weakened by audio signals of other frequencies. By adjusting the volume of each audio layer, the volume of the 40Hz gamma frequency is kept in an appropriate proportion with the background sound or the main audio, so that it will not be too prominent to affect the user experience, nor will it be covered by the background sound. In addition, through spectrum analysis and filter technology, the clarity and energy of the 40Hz frequency band are enhanced so that it can be effectively transmitted throughout the audio. This ensures that the gamma frequency always maintains its due effect during playback and will not fail due to interference from other frequencies.

[0042] The final audio file is saved to the user's device or cloud server for subsequent playback.

[0043] The video processing module is used to generate audio with a gamma frequency of 40 Hz, replace the original audio of the video file selected by the user with the generated 40 Hz gamma frequency audio, and adjust the time stamp synchronization of the video file and the 40 Hz gamma frequency audio to achieve comprehensive sensory stimulation of audio and video.

[0044] Specifically, users can select videos from the video library provided by the platform, or upload their own videos.

[0045] The video processing module will automatically replace the original audio track of the video with a processed 40Hz gamma frequency audio file. In the playback device, the player continuously compares the timestamps of the audio and video, and adjusts the playback speed of both in real time according to the current video playback rate. If the video is fast-forwarded or slowed down, the audio system will automatically perform corresponding scaling processing based on the current timestamp to keep it synchronized with the video. At the same time, the video quality is enhanced to improve the clarity, contrast and color accuracy of the video, making the picture details clearer and the colors more vivid. The frame rate is adjusted to ensure smooth video playback and avoid freezes or dropped frames. Ultimately, the user experience is improved.

[0046] The generated audio and video files can be played directly or saved for users to download.

[0047] The user upload module allows users to upload audio and video content, and detects the format of the user-uploaded content. If the user uploads an audio file, the audio file is input into the audio processing module; if the user uploads a video file, the video file is input into the video processing module.

[0048] At the same time, users can preview the converted files in the user upload module and perform operations such as volume adjustment and video editing. After the user confirms that it is correct, the system generates the final 40Hz sleep-aiding audio and video file for the user to use or share.

[0049] The content recommendation module is used to analyze user preferences based on the user's video viewing and audio listening history and recommend audio and video content to the user.

[0050] Specifically, the content recommendation module collects the historical data of users' video watching and audio listening. Based on the historical data of users collected by the data collection module, a machine learning algorithm, such as collaborative filtering or content recommendation algorithm, is used to analyze the user's preferences. Based on the analysis results, audio and video content is recommended to the user. At the same time, based on the user's feedback on the recommended content, the recommendation algorithm is continuously optimized to improve the accuracy of the recommendation and user satisfaction.

[0051] like Figure 2As shown, an embodiment of the present invention further provides a sleep promotion method based on a 40 Hz gamma frequency, which is implemented based on the above-mentioned sleep promotion audio and video system based on a 40 Hz gamma frequency, and includes the following steps:

[0052] The user's brain wave signals are monitored in real time through wearable devices to obtain the user's brain wave fluctuation state information as user state information, and the user's sleep state is determined based on the user state information. If it is determined that the user is in a deep sleep state, the audio and video system is turned off.

[0053] The present invention also provides an electronic device, comprising: a memory, a processor and a computer program, wherein the computer program is stored in the memory and is configured to be executed by the processor to implement the above-mentioned sleep promotion method based on a 40 Hz gamma frequency.

[0054] The present invention further provides a computer-readable storage medium, in which a computer program is stored. The computer program is executed by a processor to implement the above-mentioned sleep promotion method based on a 40 Hz gamma frequency.

[0055] The present invention provides a sleep promotion method and audio / video system based on 40Hz gamma frequency, which improves the user's sleep quality, shortens the time to fall asleep, increases the total sleep time, and reduces the number of awakenings at night through the comprehensive sensory stimulation of 40Hz gamma frequency audio and video. The personalized recommendation function based on user data ensures the best sleep experience for each user. At the same time, the support of user-generated content increases the diversity of the system and user participation.

[0056] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. Only the preferred embodiments of the present invention are expressed. The description is more specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. As long as there is no contradiction in the combination of these technical features, they should be considered as the scope recorded in this specification.

[0057] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
