There are lots of Audio Codec available on the internet, but FLAC stands out amongst them in quality. They are almost like the MP3, an Audio Codec, but the difference is that, this is a compressed format but still it does not lose any of the qualities of the original audio.
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 AU file after converting to FLAC may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from AU to FLAC 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 AU to FLAC does not meet your expectations, you can simply try to find on the Internet a different version of your file in AU format, properly converted to a FLAC file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file AU the desired result was not achieved, you can try to change the format of AU file to other than FLAC. 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 AU file converted by someone else, and the attempt to convert it to FLAC 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 AU file in its original format (without conversion to FLAC file). Such a solution will be difficult to implement, but it certainly will give the best result.
