Project Page

The Project Pages were created in an effort to help promote student projects. The Project Pages provide a showcase where employers, other students, and friends can see what UIUC students are capable of. Many employers, in particular, consider a good Senior Design Project to be just as valuable as internship experience. The Project Pages will develop over time into a valuable library of practical engineering knowledge. Some of the best projects will be identified each semester and placed in the Senior Design "Hall of Fame," while the rest will be accessible by semester and search engine.

Updating Project Information

Once your project has been approved on the discussion board by the Instructor, you should promptly update your project information. In order to do so, find your project on the Project page, and click its title. When a frame expands, click on "Edit." Next, enter your UIUC netid and password. The system will lookup your project and prompt you for information such as your project's title. Please fill in the information that you wish to have appear for your project, and then click on the submit button. The required fields are marked so. You can update this information at any time. We strongly urge you to keep a backup of all of the information, and we would like to caution you of one scenario in particular. If multiple people attempt to edit this information at the same time, the second person to submit the changes will overwrite the first person's changes. Also, be sure to logout when you are done by closing the web browser. It is important that you provide a project desciption. It should be a brief overview of your project and explanation of why it is worth doing. Please provide this information as soon as possible and try to limit the length to about 250 words.

Submit Schedule

After updating your project information, you should proceed to the Submit Schedule page. Here each student should submit his/her schedule so that your TA can schedule a weekly meeting time. We know that there are a lot of boxes to check, but we need this detailed information because of how difficult it is to match schedules. The information is displayed in a convenient way for TAs when it is time for them to schedule meeting times. The system is very intuitive so instructions are not needed. NOTE: Please be sure that the schedule you submit is as accurate as possible, since you won't be able to edit it later!

After submitting your schedule, you should familiarize yourself with the "Upload Files" page.

Uploading Files

This area is used to upload files such as the Proposal, the Final Paper, Images, and additional files. When a file is uploaded, it is renamed and limited to a specified size. Special documents such as Proposals and Final Papers should be uploaded into the appropriate slot and will automatically be added to your Project Page. Images and other files can be uploaded into any other slot such as "file1." To upload a file, simply select which slot to place it in, and then select the file from your computer using the "Browse" button.

Master Bus Processor

Featured Project

General Description

We will design a Master Bus Processor (MBP) for music production in home studios. The MBP will use a hybrid analog/digital approach to provide both the desirable non-linearities of analog processing and the flexibility of digital control. Our design will be less costly than other audio bus processors so that it is more accessible to our target market of home studio owners. The MBP will be unique in its low cost as well as in its incorporation of a digital hardware control system. This allows for more flexibility and more intuitive controls when compared to other products on the market.

Design Proposal

Our design would contain a core functionality with scalability in added functionality. It would be designed to fit in a 2U rack mount enclosure with distinct boards for digital and analog circuits to allow for easier unit testings and account for digital/analog interference.

The audio processing signal chain would be composed of analog processing 'blocks’--like steps in the signal chain.

The basic analog blocks we would integrate are:

Compressor/limiter modes

EQ with shelf/bell modes

Saturation with symmetrical/asymmetrical modes

Each block’s multiple modes would be controlled by a digital circuit to allow for intuitive mode selection.

The digital circuit will be responsible for:

Mode selection

Analog block sequence

DSP feedback and monitoring of each analog block (REACH GOAL)

The digital circuit will entail a series of buttons to allow the user to easily select which analog block to control and another button to allow the user to scroll between different modes and presets. Another button will allow the user to control sequence of the analog blocks. An LCD display will be used to give the user feedback of the current state of the system when scrolling and selecting particular modes.

Reach Goals

added DSP functionality such as monitoring of the analog functions

Replace Arduino boards for DSP with custom digital control boards using ATmega328 microcontrollers (same as arduino board)

Rack mounted enclosure/marketable design

System Verification

We will qualify the success of the project by how closely its processing performance matches the design intent. Since audio 'quality’ can be highly subjective, we will rely on objective metrics such as Gain Reduction (GR [dB]), Total Harmonic Distortion (THD [%]), and Noise [V] to qualify the analog processing blocks. The digital controls will be qualified by their ability to actuate the correct analog blocks consistently without causing disruptions to the signal chain or interference. Additionally, the hardware user interface will be qualified by ease of use and intuitiveness.
