I would like to hire a Lisp Programmer to modify some simple code

Hello! I need a little work done on a plug-in for the audio editor Audacity. It's written in Nyquist, which is based on Lisp. [login to view URL] The plugin analyzes audio data for files open in Audacity, and then prints that data to a .txt or .csv file. There are three modifications that I need. The first (and simplest!) is the most important. I could live without the others, for now. 1) I need the plugin to print much LESS data to the exported file. I really only need a small part of the data analysis exported. All I need is the "stereo peak" and "stereo RMS" in that export, but I am hesitant to go in and start deleting code. 2) The program can be run in Audacity as a batch process, so it can analyze a large number of audio files in one run. BUT, it will print the results to separate .csv files for each of the audio files analyzed. I would like to see a single .csv file written for all the files in a batch process. 3) The exported analysis of each audio file should also include the audio file's name in the export, too. So, I want only three items in the exported file - the audio file name, the "stereo peak", and the "stereo RMS". My eyes simply glaze over when it comes to code. Let me know if you can help!
