Recently, I’ve been changing all my music files from MP3 to AAC.
To be specific, I’m encoding my FLAC files and ripping CDs to AAC files.
You should not encode MP3s directly to AACs because they are both lossy codecs.
Some data are gone when you create MP3 files, and when you convert them again to AACs even more data will be lost.
That is no use and the output can never be better than the source.
Therefore, you should get some original files.
Lossless files like WAV, FLAC, ALAC are good sources, and you can also use your own CDs.
In this post, I’ll show you how to convert music files to AAC files.
AAC files are better than MP3 files because,
- they are compressed more
- their VBR is more efficient
- they can take the advantage of AAC bypass when your bluetooth devices support AAC codecs
When your bluetooth devices all support AAC codecs, you can get better battery life and even better audio quality.
From now on, I’ll convert FLAC to AAC.
I’m going to use XLD(X Lossless Decoder).
It seems to be developed by a Japanese.
It is a light and handy tool, and the output is in good quality.
Also, the recent update is 20151128 which means the developer is hardworking. lol
You can download the installer at the Official site.
I’m now using MBPr OS X 10.11.1 Yosemite.
After the install, start the app.
But the app is running in the dock bar.
You can also find it running in the upper left corner of the screen.
Go to Preferences or use the shortcut “Command + ,”.
Our purpose is to convert files to AAC.
So set the output format to AAC.
Click the option which is at the right of output format.
Using the settings below, you can get the same output when you’re using iTunes to rip CDs and get AAC files.
I’m suggesting these settings and I believe it will provide you with the most efficient output.
Let’s convert files.
Move to a folder where FLAC files are located.
Select all files using the shortcut “Command + a” or by dragging.
Right click and choose XLD in the app list.
You can also do the same thing by drangging the files and putting them on the XLD icon in the dock.
Files are being encoded fast.
When it’s done, you can get these M4A files.
AAC is the name of a codec and the container’s name is M4A, so don’t get embarrassed.
Now, move the lossless files to the safe place, and use the M4A files created.
You can put them in the iTunes library or use any other devices/programs to listen to them.
