When I want to produce a mp3 file, I do it as .wav first on MS Sound Recorder and then I use freeware Audiograbber to transform it into mp3 file. However, there is an option on Sound Recorder to record as mp3, but the msg is always of not having enough memory though I have 512M RAM already.
How much RAM is needed then?
And also what is the maximum size of .wav file the Sound Recorder can open? In my experience, below 150M is still OK.
