Converting a WAV file to MP3 from VBA

[GraeagleBill]

I've found several posts online as to how to convert WAV files to MP3 using 3rd party UIs, but would like to be able to accomplish the task via a SHELL interface or a similar fashion.
I don't believe there's a Windows FSO option that would copy/convert, so I'm assuming I'm still up against a 3rd party app of some kind?
Thoughts?
Thanks,
Bill

Thanks. I did see the references to LAME but shied away when I saw the requirement needing to deal with C++ distribution of the code.

Check this out maybe.

I'll investigate and run some tests. I assume from a quick look I can SHELL with a ffmpeg command string.

Yes, you could shell those. Give it a shot.

ffmpeg works as advertised. First attempt failed without any indication as to what the error might be, I had attempted to create "C:\Beethoven.mp3". I had to run the same command string from the Windows "Run app" to discover the permission error, as ffmpeg could not create a file in the root of "C:".

Windows "flashes" the screen when ffmpeg runs, so I need to somehow suppress that? Any suggestions? (It's been awhile since my DOS days )

(PS) Beethoven.wav is just the first few bars of his 5th symphony. I've uploaded that snip to my iPhone and associated that ringtone with my mistress. Needless to say, that if I forget to set my phone to vibrate when I attend a meeting and she calls, everyone in the room knows who the idiot is .
