Compress large audio file to transfer through asmx service

MP3 is already a compressed format. It's unlikely that if the files are already in MP3 format that you will be able to compress them any further without reducing their sound quality/bit rate.

Even using a different encoder, you will not be able to achieve a smaller file size because the MP3 compression method is standardized across all implementations. If your current files happen to be constant bit rate (CBR), you could look into converting them to a variable bit rate (VBR), which will shave a small percentage off the total size, but at the loss of some quality and with the risk of introducing some audible distortion. The amount that distortion will be disruptive depends on the individual; some can notice distortion even at 128 kbps, but you really shouldn't ever go any lower than 96 kpbs.
