Hi, I have problems with compressing my records from wav file to mp3. When I stop my recording, and the file size is less than 10 - 20 MB I have no problems, the program automatically compress my file and it is ok. But when my record file size is bigger than 20 MB, when I stop recording, the program starts to compress it, but after few second, the program crashes as an error, and the recorded file is lost. Can you help me? Thanks
