LabView (Sampling):
Open the file : Screen_voice_2channels_csv.vi
- The first plot shows the vlotage in the time domain.
- The second and the third plots are the FFT's from the 1st and the 2nd channel over 1 second.
- The fourth plot is the average of the FFT's.  

1. Specify the parameters: Sampler model with its channels (for example: cDAQ2Mod/ai0 in the "physical channel" dialog), path to save the file (in the "file path" dialog) and the rate.

2. Make sure the 'start buffering' and the 'Save file' buttons are on.

3. Start sampling by pressing the top right arrow which runs the script.

4. When finished click on 'STOP Recording' to save the file.

5. If you don't wish to save the file you should turn off 'start buffering' and the 'Save file' buttons and sample as usual.


DSP:

Run the main.m script in matlab. The code reads the optical signals from the folder (which we recieved from our expirements), and extracts outputs for each filtering stage into the corresponding folders: let_it_be/clocks/sentence_reconstructions.

The equalization part is done at the end on the 'noise_reduction_signal' file through Audacity. You can import our equalizer from the file:
equalizer (import the file with audacity).XML
