how to play amr audio files

amr is 3gpp standard audio format, mplayer may support it natively in near future, or you can compile the amr codec into mplayer yourself.

But I'm lazy, so when I found this amr file on internet, I downloaded it and transferred to my motorola phone with bluetooth, so that I could play it.

另外偏题一下，上面这个电话录音是当事人自己公布的，不是我窃听的。里面是中产阶级的夫妻俩在吵架，妻子借批评孩子不好好学习来埋怨丈夫不好好做自己的正事，老给家里惹麻烦，宣泄自己对cops的fear，对未来的恐惧。 情感真实，本色出演，比任何肥皂剧都感人，更有现实意义，背景信息可以看这里：http://groups.google.com/group/cuihua/browse_thread/thread/7f0a4ce23638234f
