Part 1. AAC vs MP3: Which Format Should You Use
Among lossy and compressed audio files, both AAC and MP3 are popular options. Both formats are popular because they are excellent choices for storing music files for offline use. However, they still have key differences.
Since AAC is a modern format originally designed for modern devices, it has inherent advantages in sound quality. It was optimized with advanced algorithms that deliver better sound quality and higher compression rates, even at lower bitrates.
On the other hand, MP3 files have a significant advantage in terms of universal compatibility. Although it is an older file type, this has become a strength since most hardware and media players can play MP3 files with no problem.
Simply put, AAC offers better quality and compression and, on average, is smaller than MP3. However, MP3 files are more compatible, as they are considered the universal audio format. All you have to do is choose between modern efficiency and the reliability of a tenured file format when converting AAC audio to MP3.
Part 2. How to Convert AAC to MP3
Method 1: iTunes or Apple Music (Built-In)
Best For: Importing AAC audio from Apple Music or iTunes storage to MP3 using the program's built-in settings.
To get started converting AAC audio to MP3, we will first use the built-in solution in Apple software players such as iTunes and Apple Music. Fortunately, Apple Music has a built-in Convert feature which can be used to create a copy of an audio file in your Apple library.
However, since AAC is a popular format on Apple devices, it is the default file format when using Apple Music's Convert feature. To set MP3 as the file type for importing Apple Music audio, you need to edit Apple Music's Import Settings.
Open Apple Music and click on the Music tab. Then, select Preferences.
In the File menu that will open, select Import Settings.
In the Import Settings menu, select Import Using and choose MP3 Encoder. Click OK to confirm the encoder option you selected.
With the import setting set to MP3, click File > Convert, then select Create MP3 Version. This will then prompt Apple Music to create a local file copy of the selected audio saved in MP3 format.
If you are using an Apple device and want to import AAC audio to devices outside Apple, the built-in Convert feature in Apple Music is a good choice, as it is readily available.
Method 2: Convert AAC to MP3 with Audacity
Best For: Exporting audio files to MP3 and editing advanced audio settings to media files.
Since the previous option is only available for Apple hardware, the second method we will discuss is a program available on platforms such as Windows. This will be none other than the audio editing program Audacity.
Originally built as audio editing and engineering software, Audacity offers advanced export settings for saving edited audio files in MP3 format. As such, this method provides a detailed guide to transferring AAC to MP3 using Audacity's Export Settings.
Open Audacity and select File > Import > Raw Data. Instead of the normal Open File, use the Import option to open AAC in the program, since it does not support AAC by default.
Once the AAC audio is imported, click on File again and select Export Audio.
In the Export Audio settings, set the Format to MP3 Files. Then select Export to convert the AAC file to MP3 using this third-party workaround.
When editing audio files, Audacity is a popular choice. Fortunately, its background made the tool a reliable solution for editing file formats, thanks to its advanced import and export settings.

Part 3. AAC to MP3 Settings: What Bitrate Should You Choose
When converting AAC to MP3, a good bitrate for good-quality audio is 192 kbps to 320 kbps. Although AAC may sound good even at a lower bitrate, MP3 requires a higher bitrate to maintain the same quality as AAC. As a general rule, select a higher bitrate, preferably 256 kbps or even 320 kbps, if you don't mind sacrificing a little storage space.
