Small project for signal processing

Hello guys,

I am new to this forum and I really appreciate the kind of effort people are putting in here to make others understand and improve their projects. Hats off to you people!
Basically here I am looking for some ideas on small projects in signal processing. Since this is my third year project course and I haven't taken DSP yet, I initially started out with project for gender recognition with the help of my awesome lab instructor but due to my lack of knowledge in this area and since I haven't taken courses a lot about it, it became a bit difficult when it came to reducing the complexity of the code and the hardware. So anyways I am still going on with the project which would take more than a semester for me since I want it to be much more sophisticated and advanced, but due to time restriction I want some ideas for a mini, creative and simple project which I could complete this semester for my course. The idea of the project should be simple, easier and something that would ignite a spark in mind of the one who hears about it.
Waiting for your reply
Thank you
(Sorry for such a long message)

How about some kind of audio thing? A frequency shift or something like that, something with a musical application, perhaps?

just out of curiosity, how were you going to do gender recognition? Voice or something else?

I did this dancing LEDs to music last year and I want to do something similar but I am really not getting the exact topic. Can you please be more specific and yes, I am more interested in something that involves music.
Well gender recognition is being done on the basis of the voice signals whose frequency will be decoded in Matlab. That's where I reached so far but I want to include facial recognition too.
And what's a frequency shift? Can you please tell me more detail about it's function and implementation.
Thanks for your reply

By frequency shift I just mean shifting a frequency range to a different range, for example 500-1000 Hz gets shifted to 1000-2000 Hz (in other words, shifting up an octave) This is trivial for a sinewave, but if you've got a complex signal it would be a lot more difficult. I was just throwing that out there, I don't really know how to do this properly.

I think that simplest DSP project would be something like digital FIR/IIR filter.

Few things can look at
1>Identifing duplicate music files(like .mp3) in your PC : some times we might have several copies of same song but they are of different quality(bitrate), sampling frequency etc. The music is same but recorded with different properties.
2>Tagging music files based on emotions like happy, sad, lonely, depressed, exicted etc - once user selects one song to play, based on the tag the player should continues to paly songs of same emotion.

think of different use cases that may arise in next 2 years based on explosion in smart phones/ tablets which could be good projects and add value

Those are nice ideas, but I think they are very bandwidth dependant. I mean that both things you came up with need enormous amount of data to be processed, at least at first run. I've got a USB HDD containing 230 GB of mp3's. That's more challenging because of the amount's of data which u have to process more than difficulty of the task from DSP point of wiev.

Hello how are you all???please anyone do help me i am student of 3r year of engineering and my teacher wants me to perform any small project in DSP....which seems quite difficult to do if anyone of you can please hand over me a small project i mean any simple project in DSP or can you tell me where to start because i am very tense because of this project.please help me out.my email is killerpappu@yahoo.com
