Finally I got time to use my computer. I have just verified that if I use the computer' s " voice recorder" to record the songs, I can directly get .m4a files. But if I use the asus cell phone' s "sound recorder" to record them, I will only get .3gpp files. So next time I will try to use the computer for recordings to avoid renaming the extension part. Thanks for your attention and effort!

You are welcome. But unfortunately the computer I tried today made me very disappointed. Its recording effect is very very poor though it's good in other aspects. I will not use this computer for recordings.
