Digital Signal Processing Software for OLPC
Objective
Develop a simple and scalable Digital Signal Processing [DSP] application for OLPC using python/C++.
Description
The DSP application will provide the users with the following capabilities:
- Ability to load/record audio files which must be processed using DSP filters.
- Provide pre-configured filters which will process the loaded audio files.
- Provide a method to save and playback the processed audio files.
Target Audience
- Young Students – The application will provide the young students various ways to experiment with some standard DSP filters which transform the recorded sound signal. Eg: Change of pitch/speed or special effects like that of a robot, Donald Duck etc.
- Engineering Students – The application can also be used by students enrolled in DSP courses to analyze the effect of various filters on the recorded voice as part of their lab experiments.
Plan
- Gaining basic knowledge about DSP, which would be sufficient for the application development phase. Revision of mathematical operations specifically required for development of DSP algorithms.
- Fixing the DSP effects and algorithms that will be provided as pre-configured filters within the application.
- Understanding how DSP can be done through Python/C++.
- Building a framework/algorithm class of all DSP algorithms we intend to incorporate in the application.
- Use the classes developed in the previous step within an application for the OLPC.
Existing Tools Present
- Signal Processing using C++ - SF.NET Project Page - The project provides reusable DSP algorithms that we can use for making an application for OLPC.
