Digital Talkback Report With Circuit design and C Programming Coding

The aim of this project is to develop a system that allows the user to record an audio clip and then play it back with different types of filters to manipulate the audio signal. Such a device would serve as a ‘fun-toy’ for kids to listen to themselves differently. The system will consist of a DSP/Microcontroller that will accept input audio signals from the user. During the recording phase, the user will be able to record audio clips within a specified time duration. Once the recording has completed, the user can choose to playback the audio clip in its original format. The user can also choose to apply a range of filters to the audio signal to manipulate it. Examples of filters can be, ‘Monster’, “Squeeky’, ‘Alien’ and so on. Since the device is targeted at kids, its user interface should be simple with just a few buttons to control all the required operations. The final packaged product should also be sturdy and rugged to survive in a kiddy environment.
