Introduction:

1.) I am Sanpreet Singh. I am studying in Guru Nanak Dev Engineering College,Ludhiana pursuing my degree in electronics and communication. I belief in one thing that Nobody is perfect and I am nobody. 2.) I speak English,Punjabi and Hindi. 3.) I Am a electronics and communication engineer. 4.) I am lover of removing bugs. The approach of me is to serve humanity and removing bugs is also a way to serve humanity. I will gain confidence in life that I am capable of solving problems in life and sharing knowledge accross the world. 5.) I am participating in Gsoc for the first time. 6.) The answer is very logical. Octave is a software to implement Digital signal processing.I am a electronics engineer so I need to implement programming of DSP in some software. Previously I used matlab. But I love open source so I want to use Octave. Secondly the project that I choose is of my interest.

Contact

1.) Punjab(India) 2.) My nickname on irc is Sanpreet. 3.) My Time Zone is Asia/kolkata. I am living in india and my time is 9:30 hours ahead than US. My UTC is UTC+5:30 P.M

Coding experience

I have experience in programming in c++. Digital Signal Processing was our subject in 6th Semester in which programming in which I did programming in matlab . From January I have shifted to opensource and I started using open source and I have worked on live project using open source.In my project I have used perl language to draw dynamic graphs using gnuplot.

Feeling fine

I was using matlab but when I started shifting I learned about kicad ,gnuplot,octave. Open source does not need any advertisement. The first experience with octave is when I created a account on wiki,Then a simple question was asked to me what is octave output of round(sinh(9)). So I installed octave and got the answer.

Prerequisites 1.) Ubuntu 2.) I can give 15hours per day. I like to

Self-assessment

I didnot believe in Autonomous nature. I want to be open. I donot wait for anybody to give me work. Coding is my hobby and I will work on them all throughout the life.

Your task

1.) Yes. 2.) I have selected the one idea. I liked fixing the audio processing in octave.Fix audio processing in octave: Audio processing is currently almost completely broken in Octave. Fix means there is a problem which has to be solved. Audio processing only works with linux open sound system.The Open Sound System (OSS) is an interface for making and capturing sound in Unix and Unix-like operating systems. Suggestion is make this a part of audio package but the problem is whether the core functions are lacking presently or not .If Yes then core function like play and record has to be created. Like stated above audio processing works only with LOSS(Linux open sound system). Playing and recording is done in ubuntu with the help of libraries like Portaudio and classes like rtaudio. But this libraries are not working in other operating system. Either the core functions in other operating system other than linux cannot use the above libaries and I am confident that I can fix this.

Next objective is implementing audiorecorder and audioplayer classes.I will make core function which will be platform independent which can use the above libraries. PortAudio is a free, cross-platform, open-source, audio I/O library. It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows,Macintosh OS X, and Unix (OSS/ALSA) and RtAudio is a set of C++ classes that provide a common API (Application Programming Interface)for realtime audio input/output across Linux, Macintosh OS-X and Windows operating systems. So I can make the core function but I need time to make it. I have installed XchartIRC and I have given the nickname and there we can share ideas.

Time line

17 June - 26 June

I will study Where is problem. Whether function like play or record cannot call libraries(portaudio) in all the operating system.

27 June - 7 July

The problem found above will be implemented.

8 July - 15 July

Will do the implementation of libraries on every operating system.

16 July - 23 July

Will make Some more cross independent functions that can also use the open source libraries to do some more attractive functions in octave. This I have not decided yet but I will do in this date.

24 July - 17 August

I will implement all what I stated above upto international level.

18th August Start documentation (using LaTeX or any other tool recommended) including developers documentation, user’s documentation (including MAN pages of command).
