Specification

DESC:FIELD OF INVENTION
The present invention relates to a system that enables uploading audio as well as video recordings without background noise. More particularly, it relates to a system which facilitates audio recording by supressing background noise and enhancing specific sound as well as capturing a face of the user while video recording irrespective of background ambience and noise.
BACKGROUND OF INVENTION
Thanks to the emergence of high-speed Internet and reduced prices of high-quality web cameras! Wide-spread instant messaging software supports voice/video chatting, where people can view each other while talking. Due to the advent of social media, there is a massive surge in digital content which people, businesses or governments are sharing with each other. Particularly in this new normal, it has become imperative to have audio as well as video communication without any disturbances. E-learning platforms are mandating the teaching fraternity to conduct/post/record their content in the form of virtual modules.
Most of the time it happens that content creators or normal people create video content or record audio in a noisy place. That noise in the videos and audio destroys their quality and also irritates the viewers or listeners. It may also lose the audience if the content is uploaded on any type of social media by some content creator. Additionally, content creation becomes challenging as people don't want to share their location, background scenario and face difficulty in clarity of voice recording due to noisy place, etc. Technically speaking, noise in audio and video recordings is defined based on audio frequency and audio decibel, which is loud, disruptive and out of the comfort area to human hearing. Also, all kinds of unwanted sounds in video recordings are noises. It could be wind sound, man's vocal cord, motor noises, etc. For example, when a song is recorded, all sounds except for human voice are noises; when a person mainly wants to collect ocean wave sounds, then all the others are noises.
It is to worth noting that extremely loud noises cannot only harm hearing but also speaking abilities. Inability to speak and understand each other may lead to miscommunication and affect productivity.
Secondly, there are privacy concerns with video conferencing as Social Etiquettes in real life are ingrained into our social life. Also, people from rural area who are not exposed to the social media much yet have skill sets which can be showcased to be useful to the world. In such cases there may be unwanted fear, embarrassment while appearing in front of such virtual platforms which obstructs the presentation of their skills to outside world. Such people are remaining deprived of the due credit and remuneration they deserve just because they find it difficult and uncomfortable in communicating with the world with the help of available digital platforms. In such cases the usage of social media more frequently increases FOMO and feelings of inadequacy, dissatisfaction, and isolation.
In case of virtual communication platforms available at present, such as ZOOM, Google Meet, etc. offer options like blurring of the background or applying virtual background so that the surrounding of the attendant is avoided from facing any awkward situation yet there is no provision for reducing or eliminating the background noise.
Disadvantages of the existing platforms:
? The prime requirement is to have perfect lighting conditions either natural or studio based. This is because it also takes into consideration the background of the end user.
? Production time and cost is more. An experienced visual effects supervisor for perfect video shooting needs to be hired which involves time as well as cost factor. These platforms have their set standards which need to be complied to get high quality video recordings which is not in the purview of all the common end users.
? Spills: The presently available platforms pose a risk of leaving coloured spill on the edges of character and prop if optimum distance is not maintained between the camera and the end user.
? Some platforms offer background and have a risk of the user’s cloth colour matching with the background colour.
The above-mentioned points reveal that in case of video recordings, the existing platforms need to emphasise on the exterior factors such as presence of adequate light, have limitation on the cloth colour of the user, need of hiring expert professionals, etc.
Thus, in order to contribute as a social impact by encouraging all segments of people to open up, express themselves for boosting their confidence and protecting their privacy requirement, it is evident to have a universal system. Hence, a need exists for a noise reduction and face isolation system and method that offers audio and video recordings with enhanced quality and least noise with face catching feature.
The proposed invention takes care of awkwardness of the user being afraid/ concerned about the location, distraction, attire, etc. Moreover, this invention will help people from rural places to express themselves without hesitation and also to sell/ highlight the product, services or the skill set, etc.
