To Encode a Mp3 file to another Mp3 file

[Angelo405]

To encode a Mp3 file to another Mp3 file [both files on local disk], for such purposes like changing bit rate, etc., is the following graph correct? If not, what correction should be made?
File source [Async]-->MPEG-I stream splitter- -> FFD show Audio Decoder- ->LAME Audio Encoder- -> Dump.

The graph must work (with ffdshow properly configured: mp3 input enabled, wav output).

You can use also the default decoder MPEG Layer-3 Decoder (l3codecx.ax) instead ffdshow.

And, of course, lame.exe directly in command line.

You need not follow the graph to do your work. Just open the Mp3 files in any audio editing software, try this with FlexiMusic Wave Editor (http://www.fleximusic.com/waveditor/overview.htm), in this save the Mp3 file using the command “Save As”. While using this command, it will ask for change in bit rate where you can change the bit rate of your choice.
