I want to convert 5.700 .m4a (apple lossless) files which I have bought from an old disco remix label on hard disc to .wav with the batch process in Wavelab 8 on Windows 7, 64-bit …
But the batch convert doesn’t want .m4a.
In the manual I’ve read with Quicktime installed it works - but only on 32-bit …
Is this correct and/or any other recommended solution?
Why not install WL8 32-bit on your Win7? Makes no difference in the resulting files, and if you have no other use for it anymore you either uninstall or wind back to a Windows restore point.
Yes, that should be no problem. I used to have WL7 in both versions on my Win7 PC, and uninstalled the 32-bit version to just have WL6-32, WL7-64 and WL8-64 - I have no reason anymore to hold on to WL7 so I might just uninstall that too.
No guarantees ofcourse, but on my PC, nothing was affected on the other WL installation(s) - not sure whether WL6/8 were already installed at the time.
I’ve just installed Wavelab 8 (32-bit) and Quicktime 7.7.4 on my Windows 8 laptop.
Converting is running superb with all 8 cores - only at the beginning …
I noticed that Wavelab 8 permanently swaps between the windows “Operation in progress …” and “Batch Conversation” and bring the one or the other always on top. Seems to be a bug in Wavelab 8 (maybe only with m4a files - didn’t had this problem with 10000 .wav to .mp3).
When starting with "Operation in progress … " window - not with the first files(!) - then all 8 cores are not used anymore - only one file after the other. Seems to be another bug.
Also I miss the output of the converted file to the source folder. But with the tags stored in the file I’m able to re-create the original directory structure with Tag & Rename, etc.
A follow-up problem of only one output folder is that duplicate file names (unique in each sub directory) have to be renamed before this batch starts.
However - after ~ 50 minutes 650 files have been converted and is still running without any problems.
Wavelab 8 batch conversion didn’t copy the tags from a .m4a to a .wav file (as for .wav to .mp3). So I am not able to re-create the correct order of the directory structure from the tags …
I think the other way is to use some kind of third-party converter software to solve this, so maybe you can use them for convert m4a to wav or to MP3, or ACC and then you can play the music files.
