Team Project proposal: Phone audio beautification app--by Kun Qian

Two months of internship in Asia Hospital. After listening to the scripted < Software engineering > class in school, I didn't learn anything other than drawing all kinds of pictures. Naturally, there is a high expectation for the ASE courses offered here. No matter what kind of project, need to personally, work together to complete the task, teamwork ability is very important. This project is a very good opportunity. Consolidate what you have learned in practical use. For a team of software engineering projects, feasibility, market demand, technical requirements, etc. are the factors to be considered. Smartphones have evolved to a very high-end level, and there are numerous beautification apps, but almost all of these applications are processed for photos. There are few landscaping apps that use mobile phone recording or voice. Therefore, I recommend "Mobile audio beautification App" as our topic

Now people are very accustomed to take pictures with mobile phones, leaving some memories, can be turned over at any time. So now there are the United States 美图秀秀 and other types of mobile phone software user-friendly, so that the photos more beautiful. In contrast, there are few software for sound processing. When you catch a star to record a song on the scene, go back to find that because the fans are too crazy to hear nothing, when you stop for a street artist, but found that the traffic is nothing down, when you are speaking to important people important words, and then found that just a passer-by a sneeze--_--| | You'll find that the sound recorded on your phone is just as important. This app is meant to be able to use the phone for audio collection when the input sound denoising and appropriate landscaping, so that the use of the phone's audio function can be very satisfied with the experience.

Project analysis: Although the same type of products are very small, but in the academic world there are many effective ways to diagnose and remove the noise people do not need. And with the voice album such as network products more and more popular, mobile phone users for audio beautification of the app's demand is also a potential improvement.

1. Demand:

The user does not need to select or adjust, and the audio is automatically processed and de-noising when the audio is entered.

2. Implementation process:

The user enters a piece of audio, first the noise is identified by an audio recognition algorithm based on the feature of the compressed domain.

Then use the Spectrum subtraction audio denoising method to go out of the audio noise.

Finally, post-processing output is performed for the audio.

1. Advantages:

Very few user actions are required to de-noising and beautify the input audio without affecting the user's normal function of the phone. Good compatibility, no need to deliberately open and close.

1. Competitive Advantage:

Currently for mobile phone audio processing of mature apps very little, a lot of audio post-processing is done by the computer, in contrast to the direct use of mobile phone processing will be very convenient and fast. And this process does not require additional customization of any hardware or functional components, portability is very good. With the current multimedia era of continuous progress, mobile phone audio beautification app in the future development space will be more and more big.

Through the above analysis, the product in the market, demand or technical feasibility is relatively high. And after the completion of maintenance is also relatively convenient. In this large framework, the future of better audio processing methods can also be more convenient to join the system. This idea can be one of the major assignments for our ASE program.
