Hi Guys
Am trying to add a voice track for the first time. I recorded my client saying her piece, using my iPhone. Which produces MP4 files. Try as I might, I cannot convert the MP4 to MP3 or WAV files. Is there a workaround? Any recommendations? I've tried the Windows 'My MP4 to MP3 Converter', ITunes, and a couple others but none of them can see the MP4 file in the first place. If they do, (ITunes) they 'convert' it to MP3 or WAV but there's nothing there, just the original MP4. Which calls itself .m4a

Any thoughts? Have any of you encountered this problem? I know it's not Reallusion product related, but you guys may have some answers so here I am.

Use Audacity (Freeware):
https://sourceforge.net/projects/audacity/
Here is a tutorial how to do it:

Thank you! Will try.

ToyStoryLab, I am beside myself. Thank you so very much. It works like a charm. Very grateful  to you! Was at my wits' end.

And while you're in Audacity...

a) Copy the original track, so you have the unaltered original recording - I always try to work non-destructively
b) Apply NOISE REDUCTION
b.1) It's a two-step process
b.2) First you select a "quiet" section, ideally several seconds long, to provide a reference for the background noise
b.3) Then you apply the noise removal

Wear headphones while doing this.
It is amazing how much background hum and hiss there is, even in a quiet environment.

You can "preview" the noise reduction, and you can toggle a switch to listen to either the good audio you're keeping, or listen to the noise that's being removed.
The default settings tend to be reasonable, but you can make adjustments (trial and error for me).  Just know that if you get too aggressive it will eventually distort the sound.

Good luck, and have fun.

For converting audio and video files of all types try anyvideo converter free. As it name implies it is free and it is fast, allows gpu video encoding, audio substitution, and also converts any video to audio, and Works as an audio converter. Another converter that is awesome, also free, but more nerdy is xmedia recode
