is possible retrieve information id audio signal ?

first, need sure of information want audio file , if format audio signal in supports storage of meta data.

the following formats have data associated them:
1. wav: may need read wav header getting data such sampling rate, bytes per sample etc.
2. mp3: each mp3 file comes id3 tag. these id3 tags contain information such date of recording, artist, album, track etc. these tags optional , not mp3 files may have them. need find id3 editor/reader @ information. place start can here.

take @ android documentation. there may inbuilt (especially wav formats - sampling rate etc.) already.

hth,
sriram.
