Problem: If you have not a microfone in your pc, it fails the initialization.

Possible solution: The program get a default input audio device at startup beacause it initializes the real time plot. The best option is to open the program, with the graph stoped and then and ask the user to select device source. The other solution is to open, check if there is a microfone and asks the user to plug and restart the program - this should be more easy and an option for while.

Disconnecting the microfone after initializes the program, freezes it also. Needs restart.

There is a problem with our sample rate. When we change it, the sample rate (timer) of the plot is changed and the sample rate for acquiring data (audio sample rate) is changed too. Sample rate less then 10 Hz is not compatible with the sound board. The range, simplified, is from 1kHz to 40kHz.

My suggestion is to use unchangeable value for the plot's sample rate (slowest one) and we just change the sample rate for acquisition (that determines how big would be the file - number of points).

I don't know if any value is possible between the range I said, if not, we need to put a selection input with static values.

Data exported to CSV file from the recording window will be exported just for the exhibited data, if the user apply zoom to the window, the data that could be seen is the data that will be saved.

This must be warned for the user to avoid losing data,

I put a print here.

Use home folder, documents or desktop, or even create a folder for Wavy Data when first start the program and always open this folder.
Now it is saving on base path of the program.

Some place has a variable float to indicate indices for a vector. New versions of Python not accept this anymore. This problem could be seen when export an image of a graph using new versions of Python.

I've calculated the periods for the curves that we acquired using your software and the Pasco software. Your software is acquiring the half of the amount. Wavy provided t = (0.58 +- 0.07)s and Pasco t = (1.18 +- 0.08)s.

Here is the message:

Traceback (most recent call last):
File "/home/pizetta/workspace/wavy/wavy/gui_wavy.py", line 119, in updateplot

We need to implement a save function that save the data recorded in the RecordingPlotter (the sub set of real time plotter). May we can use the numpy function savetxt and loadtxt (like .dat format, in columns). I think this is the easiest solution.

Also, we need to check the recorded file before begins a new one, or when the program closes, etc.

Using "ç" or some accent in the filename won't work, but it does not say anything, just don't work and you could lose your data.

Traceback (most recent call last):
File "C:\wavy\wavy\gui_wavy.py", line 533, in saveFileAs
self.filepath = os.path.splitext(str(path))[0]
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe7' in position 8: ordinal not in range(128)

Just to allow the user to save data again, create the button for save as, using the same format.

Pause action needs to be reviewed, because the time that they put when you pause and restart the recording is not the same of the real time window.

Some options:

• remove pause action
• put the right time from real time (including when the you start acquiring first time)
• do nothing - because the time (when you acquired) is not important
