audio format converter

A Command Line Interface program that converts a .wav audio file from GSM 6.10 format to CCITT u-law Atributes 8.000 kHz, 8Bit, Mono 7kb/sec. (usually call G.711) I'm including two audio files: [login to view URL] a wav file with GSM format, and [login to view URL] file with the G.711 format. The program must receive as arguments the file name and path (example c:\[login to view URL]) and output file name and path (example c:\[login to view URL]) The program has to be able to run up to 100 times at the same moment in different sessions. (Example in the same second I can call four times the program to convert 4 diferent files to the g.711 format ) Doesn't matter the programmer languaje, but it will be good if it was made in java or VB ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows 2000 server and Profesional WS.
