AAC has been recommended by many experts as the superior audio format. This is due to it being able to preserve digital tracks better than MP3s at a higher bitrate, but will AAC be enough? If not, what can we do to improve sound quality even more on our digital devices?
The “aac vs mp3 which is better” is a question that has been asked many times. The AAC format offers higher quality than MP3, but the MP3 format provides more compatibility with devices.

There are many concerns concerning the performance of the AAC and MP3 320 audio encoding formats, as well as which one is preferable. This page was designed to address some of them and to serve as a guide to determining which of the two formats to use by comparing their performance, the benefits one has over the other, and the devices with which they are compatible.
Because AAC can perform a better job at the same bit rate or an equal job at a little lower bit rate, it is a superior codec over MP3 320. This indicates that AAC 320 is superior than MP3 320, but you won’t notice the difference. It’s possible that you won’t notice the difference between AAC 256 and MP3 320. MP3 320, on the other hand, is compatible with a wider range of devices.

What Is AAC and How Does It Work?
Advanced Audio Coding (AAC) is a digital sound archiving standard that was developed to replace the MP3 format.
It can encode sound to a greater quality (particularly in low-bit-rate audio files) while maintaining the same file size as MP3.
Sony, Nokia, LG Electronics, NEC, Bell, Dolby, NTT Docomo, Panasonic, and Fraunhofer collaborated on the project, which was released in 1997.
What Is MP3 320 and What Does It Mean?
MP3 320 is an MP3 (MPEG 2, Audio Layer 3) audio storage format that can encode sounds up to 320 kilobits per second, but not more (kbps).
It signifies that the encoder can save excellent sound at the greatest rate of information, which is 320kbps.
As the pace of information rises, the sound accuracy decreases. Karlheinz Brandenburg created the MP3 format, which was first published in 1991 and updated in 1994.
AAC’s Advantages Over MP3 320
Aesthetic Appeal
At the same bit rate, AAC can encode higher-quality sound than MP3: AAC was created using an algorithm that allows it to compress sound more efficiently than MP3, resulting in sound that is as close to the original as feasible.
Unlike MP3, which employs a blend of MDCT and FFT, AAC’s encoding process is entirely MDCT (Modified Discrete Cosine Transform) (Fast Fourier Transform).
At a lower bit rate, sound quality improves.
AAC may also encode sound with about the same quality as MP3 at a lower bit rate: AAC can compress equal sound quality to MP3 in lower file sizes due to its ability to compress sound more effectively, giving it a significant advantage over MP3.
File Size
When it comes to audio files, AAC excels at lower sizes: AAC encoding helps preserve audio quality in smaller files when MP3 might cause sound distortion.
Range of Frequency
With a frequency range of 8 kHz to 96 kHz, AAC can encode more accurately than MP3, which only has a frequency range of 16 kHz to 48 kHz.
Channels
AAC has more channels than MP3: MP3 can only sync two audio channels, but AAC can sync 48.
This provides it more sound encoding flexibility and accuracy, as well as the ability to operate seamlessly with multichannel audio files.
MP3 320 has a number of advantages over AAC.
When Bit Rates Are Higher
At higher bit rates, the quality of MP3 320 is approximately identical to that of AAC: the difference in quality between MP3 and AAC is essentially undetectable as the bit rate increases.
The AAC format’s benefit is only noticeable at bit rates of 198kbps or below, which is not a particularly popular bit rate among audiophiles.
Compatibility
MP3 is more widely supported than AAC: AAC is mostly found on Apple devices, since it is the chosen encoding format for Apple Music and iTunes, but MP3 is supported by a broad variety of devices, including those running Android and Windows.
Despite the fact that both formats can be played on any device, MP3 is still the most popular.
MP3 is more popular: MP3 has a popularity edge than AAC since it is older and more readily accessible. Most digital sound systems now use it as the standard audio encoder.
AAC at 128kbps vs. MP3 at 320kbps
AAC encodes audio recordings of high observable quality at low data rates, which is a fact. While MP3 is recognized for producing high-quality music at 320kbps, AAC can generate remarkably good sound at 128kbps.
320 MP3 is, nevertheless, much clearer than 128 AAC.
MP3 320 compared. AAC 192
The sound generated by AAC at 192kbps is fairly clear for that bit rate; yet, the sound quality is still inferior to that of MP3 at 320kbps, but the difference is not as great as in 128 AAC.
Some may claim that 320kbps is clearly superior than 192kbps, however given the frequency range and encoding advantage that the AAC format has over the MP3 format, comparing them at both levels is not absurd.
256 kbps AAC vs. 320 kbps MP3
At these two settings, the sound quality generated by both encoders is almost identical. It’s no surprise that AAC can create a more or less similar audio standard at lower bit rates than MP3 (and at 256, it tilts toward more).
At lower bit rates, where MP3 would naturally begin to cause distortions, AAC performs far better than MP3.
MP3 vs. AAC vs. WAV
WAV (Waveform Audio File Standard) provides the highest audio quality of any audio encoding format, yet at a size comparable to MP3 and AAC.
While the MP3 format generates relatively high sound quality, it is the least performant in this area when compared to the other two; nonetheless, MP3 file sizes are much lower.
The AAC format is a wonderful balance between size and quality, retaining high-quality sound at reduced data rates.
AAC File Size compared. MP3 File Size
MP3 files are found to be somewhat smaller than AAC files at the same bit rate, and AAC files have superior quality, however AAC files have the benefit of keeping compression quality since AAC can generate equivalent sound quality to MP3 at a lower bit rate.
MP3 320 vs. M4A 256
M4A (MPEG 4, Part 14) is a more complex and higher-quality audio encoding standard than MP3.
M4A has a clear edge in terms of quality, whereas MP3 has the benefit of device compatibility, since it is the recommended standard audio encoding format on a broader number of devices (including Android devices and devices with Windows operating system).
256kbps M4A will generate equivalent (or better) sound quality than 320 MP3 based only on encoding quality.
Conclusion
After comparing the two encoding systems at different frequencies and file sizes, perhaps this article has provided you with enough valuable information to help you decide which format is best for you. When it comes to high-fidelity recording, AAC is the codec to choose. The difference between AAC and MP3 is insignificant at higher bitrates (greater than or equal to 256kbps). Furthermore, bear in mind that MP3 320 is compatible with a larger number of devices.
