从 .mp3 转为 .amr 格式
Why:
Most mobile phones are not able to play MP3 audio files, but they can play (MMS) AMR audio files
MP3 audio files are relatively large for mobile phones, AMR files are 3-6 times smaller in size
Previously the user would have to manually convert each podcast file, now it's automated
Most mobile phones audio players do not have a "rewind" button. Thus if the playback is interrupted by a call etc, the user will have to listen from the start of the podcast. With this software, the podcast is split into 10 min segments, hence resuming playback is not as disruptive
