As part of my Signal Processing class I was asked to develop an
application that make use of signal processing theory, our professor
suggest us to use Matlab, since I’m an linuxista I start writing my
application in Octave and realize that for an graphical front end it
was going to be more difficult to integrate an GUI, so I decide to go
for Python, Scipy, Matplotlib and PyGtk.
As result I develop Sigbox “An PyGtk app for digital filter design”,
some of the features are:
- FIR filter design
- IIR filter design
- Load audio wav files and display
- Frequency representation
- Inverse frequency representation
- Power sprectrum
- Cepstrum
- Apply filter
Python is one of the programming languages that I like the most,
since is extremely powerful and simple to use.
I still need to make some bug-fixing, specially in the setup script,
but I’m happy with the status of the project and that I receive a good
note on my project, but more important is that I present to my
classmates alternatives for software developing using open source tools.
