LDAC vs. AAC Choosing the Right Bluetooth Audio Codec for Your Device

Choose Right Bluetooth Audio Codec for Your Device

Bluetooth technology has come a long way since its inception. Today, it’s an integral part of our digital lives, connecting our headphones, earbuds, speakers, and various devices seamlessly. However, when it comes to wireless audio quality, the choice of Bluetooth audio codec can make a significant difference. LDAC and AAC are two popular audio codecs in the market, and choosing the right one for your device can greatly impact your audio experience.

What Are LDAC and AAC?

LDAC (Low Complexity Communication Codec):

LDAC is a high-resolution audio codec developed by Sony. It’s known for its ability to transmit high-quality audio over Bluetooth connections. LDAC offers three different bit rates: 330 kbps, 660 kbps, and 990 kbps. The higher the bit rate, the better the audio quality but also the more data it requires to transmit.

AAC (Advanced Audio Coding):

AAC is another audio codec that’s widely used and known for its efficiency. It’s the default audio codec for Apple devices and is supported by many other manufacturers. AAC provides good audio quality while being relatively conservative in terms of data usage.

Comparing LDAC and AAC: The Battle of the Codecs

Now that we know what LDAC and AAC are, let’s dive into a detailed comparison to help you make an informed decision.

Audio Quality:

  • LDAC: LDAC offers exceptional audio quality, especially at its highest bit rate of 990 kbps. This makes it a top choice for audiophiles who crave high-resolution sound. It supports 24-bit/96kHz audio, which is close to the quality you get from a CD.
  • AAC: AAC, while not as high-res as LDAC, still provides excellent audio quality. It supports up to 48kHz audio at 256 kbps. For most users, this level of quality is more than satisfactory.


  • LDAC: Originally developed by Sony, LDAC was primarily found on Sony devices. However, it has become more widely adopted and can be found on some Android smartphones and third-party headphones.
  • AAC: AAC enjoys broader compatibility. It’s the default codec for Apple devices, which means it works seamlessly with iPhones, iPads, Macs, and Apple Watches. Additionally, AAC is supported by many non-Apple devices.

Data Usage:

  • LDAC: As mentioned earlier, LDAC offers three bit rates. The higher the bit rate you choose, the more data it consumes. If you’re concerned about data usage, you might opt for a lower bit rate.
  • AAC: AAC is relatively data-efficient, making it suitable for streaming and listening to high-quality music without consuming excessive mobile data.


  • LDAC: LDAC generally has a higher latency compared to AAC. While this may not be noticeable when listening to music, it can be a factor when watching videos or playing games.
  • AAC: AAC has lower latency, which makes it a preferred choice for applications where audio and video synchronization is critical.

Choosing the Right Codec for Your Device

Now that you understand the differences between LDAC and AAC, how do you choose the right one for your device? Here are some considerations:

Device Compatibility:

  • If you’re in the Apple ecosystem and primarily use Apple devices, AAC is the natural choice. It’s natively supported across all Apple products.
  • For Android users, LDAC might be available on your device, especially if it’s a Sony smartphone or a high-end Android device. Check your device’s settings to see if LDAC is an option.

Audio Quality Preferences:

  • If you’re an audiophile and demand the highest audio quality, LDAC at its maximum bit rate is the way to go.
  • If you prioritize good audio quality but don’t require the absolute best, AAC offers excellent sound without excessive data consumption.

Usage Scenario:

  • Consider how you plan to use your device. If you’re streaming high-quality music or watching videos where audio and video synchronization is essential, lower latency AAC might be preferable.
  • For casual music listening, LDAC’s higher bit rates can provide an immersive experience.


In the battle of LDAC vs. AAC, the choice ultimately comes down to your device’s compatibility, your audio quality preferences, and your intended use. LDAC shines in the audio quality department, especially for high-resolution audio enthusiasts, but AAC offers excellent quality with broader device support and lower data consumption. Assess your priorities, and you’ll find the right codec to enhance your wireless audio experience.


1. Is LDAC better than AAC in terms of audio quality?

  • LDAC offers higher potential audio quality, especially at its highest bit rate, making it a great choice for audiophiles. However, AAC also provides excellent sound quality and is more widely supported.

2. Can I use LDAC with my iPhone?

  • While LDAC is not natively supported on iPhones, some third-party apps and devices may enable LDAC support. However, AAC is the default codec for Apple devices and works seamlessly.

3. Does AAC use less data than LDAC?

  • Yes, AAC is generally more data-efficient than LDAC. If you’re concerned about data usage, AAC is a good choice for high-quality audio streaming.

4. Are there any noticeable differences in latency between LDAC and AAC?

  • Yes, LDAC typically has higher latency than AAC. If low latency is crucial, such as for gaming or video streaming, AAC is a better option.

5. What is the best bit rate for LDAC to balance audio quality and data usage?

  • The best bit rate for LDAC depends on your preference. If you want the highest audio quality and don’t mind the data usage, go for 990 kbps. For a balance between quality and data conservation, 660 kbps may be suitable.
