WARNING: In order to run this script you must also make sure to have installed ffmpeg, it also needs to be added to your PATH environment variable. Depending upon the version of Python you are running you may or may not have it already installed. For further documentation on how to properly install ffmpeg please refer to the installation site.
As of now, this project uses a list of csv files contained in data\test_data (you will have to create this directory) and the sampling frequency is set to 48 KHz. Our script loops through the directory and converts each csv file into a data frame with 2 columns, we are supposing that the files contained a stereo signal.
Then it merges the signals to create a mono file, and finally a FFT (Fast Fourier Transform) is performed on the signal. The results are plotted considered a frequency domain of around 20 KHz, then they are saved in images.
Keep in mind, this is just a beta version of our project. We plan to implement further features such as:
- Numerical matching
- Capability of receiving a signal from a microphone
- A GUI
- Small audio preprocessing module
- Our own implementation of the FFT
