Can't open .m4a files

Jim_Kent · May 19, 2013, 4:18am

For some reason I can’t open .m4a files. It used to work. Now I get “Special File format” window. Any suggestions?

Using which WaveLab version, and 32 or 64 bit version?

Jim_Kent · May 21, 2013, 11:02pm

Wavelab 7.2.1 (build 600) 64 bit thanks PG!

m4a files can only be opened with WaveLab 32 bit.

Jim_Kent · May 22, 2013, 2:44pm

Aha! Right you are. The 32 bit version can open them. Thanks PG!

I’m using only WL 64 bit in Windows 7 64 bit. I don’t even think I have Windows Media Player on my PC. When I click on the .m4a file nothing happens.

Can anyone suggest a free .m4a to .wav converter?

iTunes or Foobar.

Thanks bob99.

Funny…I can’t open a .m4a file in either Wavelab 8 32 or 64 bit!

You need to install quicktime.

Okay got it.

For Wavelab 7 32 bits install Quicktime.

For Wavelab 8, according to your other post in the Wavelab 8 forum it will not work in either 32 or 64 bits?

Wavelab 8 is like 7 here: you need to install quicktime to open aac files in 32 bit.

The Solution that worked for me after many hours of trying was to install Quicktime Alternative:
windows10download[dot]com / quicktime-alternative / download[dot]html
Sorry cannot place linx here replace [dot] with , and remove spaces. Or search w. Google.
The Codecs from this software work not only for Wavelab but for about any program needing Quicktume codecs…
System Win10X64, Wavelab 7 latest version x32,
