Audio Cutting Software

i need a small and stable software which will run in a windows 7 environment and do the following. 1. Crop a continuous audio stream into small parts based a defined time. For example if i set the crop as 5 minutes in the settings, it will cut it every 5 mins and save that into a defined folder. 2. the cropped file should be saved as mp3. 3. i should be able to start/pause/stop the process. 4. I need start a new session(i will write session name here), and close a session . Each session will create a session folder which the audio clips will be stored. 5. i need to be able to define the file numbering for each session like . if i say save it as 01 onwards. it should say [login to view URL], [login to view URL] and so on. 6. Simple design, and layout , easy to use. . i need this really quick.
