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(primarily for fun) with some standard DSP filters which transform the recorded sound signal. They can manipulate their recorded voices and then make their friends and parents listen to it. 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

1. 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.
2. Fixing the DSP effects and algorithms that will be provided as pre-configured filters within the application.
3. Understanding how DSP can be done through Python/C++.
4. Building a framework/algorithm class of all DSP algorithms we intend to incorporate in the application.
5. 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.
