Hi,
I can open and play .m4a files, but batch converter does not work with .m4a files.
SoundForge Pro 10
SF does not natively use the <.m4a> extension. However an .m4a is just like an MP4 file without video and both use an AAC codec. Encode your files in an AVC/MP4 format , but do not include video. You can then change the extension to.m4a if you so desire. If you have a lot of files, many batch rename utilities can change the extension as well as the file name.
SF-10 should playback files with AAC audio. If you would like an m4a file to open in SF, change the .m4a file association.
I'm sorry Rick, I don't understand that last sentence. What should I change the .m4a file association to?
That is, only if you want m4a files to open in Sound Forge, for instance, instead of the Win Media player, WinAmp or VLC. Like MP3s, lossy, M4a files and such are an end-user format and not good for re-editing,
FWIW, you could also have an 'Open in Sound Forge' option for M4a files in the context menu. I use "Default Program Editor utility a lot, in which you can change file icons, file descriptions, context menus, ect., without going into the registry
Even before I associate m4a files with SF, if I try to open m4a files in SF, I get a message about installing QuickTime. That's still a prerequisite, right?
Yes, on older versions, QT must be installed for mp4 varieties and such. I think a legacy version of QT is better. QT 6 or 7 as I recall
I just tried on my laptop that only has SF Pro 13 64 bit installed, and it asked for QuickTime, so maybe it's not just older versions? Oddly, on both systems, the windows built-in player Groove Music can play them so I'm not sure what's up with that.
That is possible,
The Groove Music codecs may be locked in, and not not be available for Vegas.
Anther option is the K-Lite Codec Pack, however it was stated on the VP forum it messes up the VP default video encoders, so I uninstalled it. I never had an issue with it however.
