OGG files refer both to audio and multimedia container files. This means, that they may include compressed audio, video or text data (for example: subtitle) and metadata. This fact went out of date in the year 2007. Since that time, the Xiph.
M4A (short for MPEG-4 Part 14) is an audio file which uses MPEG-4 multimedia container format to store data. MPEG-4 file extension is officially known as MP4, and such files can store both audio and video data. However, M4A files can only store audio data.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the OGG file after converting to M4A may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from OGG to M4A to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting OGG to M4A does not meet your expectations, you can simply try to find on the Internet a different version of your file in OGG format, properly converted to a M4A file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file OGG the desired result was not achieved, you can try to change the format of OGG file to other than M4A. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your OGG file converted by someone else, and the attempt to convert it to M4A on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the OGG file in its original format (without conversion to M4A file). Such a solution will be difficult to implement, but it certainly will give the best result.
