Firefox Extension: How to render waveforms in audacity?

How to render waveforms in audacity?
Hi guys, I have recently installed the Audacity application in my PC. I just wanted to render the waveforms in application. In this case I don’t have Idea. I have searched in Google but I didn’t find any solution for this issue. Can anyone tell me what does audacity uses for rendering waveforms? I just wanted to use my audacity to create “waveformgenerate infile.wav outfile.png”.

Hi, actually audacity uses WxWidgets for the GUI elements. WxWidgets is nothing but cross platform toolkit which is use for creating c++ GUI application. One more thing I just wanted to tell you, audacity generally uses the block files for data rather than original data stream. Here the waveforms graphics are encoded into the .AU data files. One more thing I just wanted say is audio files reads in the audacity and then exist in the form of raw 32 bit data within audacity project, so therefore I would there is no direct wav or PNG.

If you still not able to solve this issue, I would recommend you to use FMODE might be better for you. One more thing I just wanted to say you about FMODE, its download come with the visualization example. You know it also has important support for managing Audio files. You can download this below given site. http://fmod.org/

I don’t know whether above one will help you or not. I would say this may not be relevant to what you trying to do. Dude, I have the some experiments on different waveforms visualization. Whatever I have searched, it is based on the code from freesound.ORG. I was trying to do something new ways to display the waveforms in the audacity. The basic ways that most people do they divide the waveform into chunk. They divide in such way that one for each pixel of output and they find the maximum and minimum sample values after that they draw pixel accordingly which I most common.
