You can pass the desired output filename as a 2nd argument, right after the input filename.
Setting up a context menu item is a little trickier. [a href='index.php?showtopic=58166']This discussion[/a] (found via the forum search function) might be of some help.
I want to encode wav files with the options --vbr-new -V0. With what exact command line do I do this, and also make lame strip the .wav extension (without typing the whole new filename)? Currently, my files get the extension filename.wav.mp3.The line I've been using islame --vbr-new -V0 "Artist - Track Name.wav"
FOR %F IN (*.wav) DO lame.exe -V0 "%F" "%~nF.mp3"
cmd.exe /C "cd "%L" && FOR %%F IN (*.wav) DO "E:\apps\lame-3.98.4\lame.exe" -V0 "%%F" "%%~nF.mp3""
