Text data to wav file

Hi there,

I converted an oscilloscope data to a text file. The data is just a 1kHz sine wave and the text format is in CSV with time in the first column and the amplitude data in the second column.

How can I translate this data file into a 1kHz wav file?

I tried a program called csv2wav, but I only get clicking sounds. I also tried finding a Matlab solution, but I haven't found one, yet.

Any tips?

Thanks!

Ditto. In Matlab, you should just be able to load up the data from the .txt file using "load" and then create a matrix of just the second column of amplitudes. You pass into Matlab's sound functions the sampling frequency so you do not need the time info. If you did not have a constant sampling frequency then I'm not sure you can play it without having to interpolate it onto a constant sampling rate.
