We purchase our own headphones and put them under the same test bench, so that you can compare the results easily. No cherry-picked units sent by brands. The efficiency of the codec will determine the quality and rate at which the audio data is sent. However, since this codec has a relatively high latency and may be a bit lossy, companies have developed their own encoding algorithms, like Samsung's UHQaudio and Sony's LDAC.

The next generation of aptX

It is capable of bit rates up to kbps with a sampling rate of It provides fairly good audio quality without requiring a lot of processing power to encode or decode. However, the audio quality can be a bit inconsistent at times. This is especially noticeable with a cheap Bluetooth transmitter.

This codec is mostly popular with Apple's iTunes platform and some other non-wireless applications. However, it's not very common, especially for headphones. It's ideal for demanding audio applications since it encodes audio more efficiently and at a slightly higher rate than SBC.

There are also two additional variations, aptX Low Latency and aptX HD, that either drastically reduces the latency of the connection or significantly improves its audio quality. So, for now, our comparison will focus on the differences between SBC and aptX. Learn more about Bluetooth. The default sub-band codec SBC works well for most audio applications. However, the subtle audio quality differences may be noticeable to trained ears and more critical listeners.

Below are a few samples of the same headphones using aptX and SBC. Can you tell the difference? As you may have noticed, it's difficult to tell the difference between SBC and aptX by ear. This shows that Frequency Response and Total Harmonic Distortion alone are not sufficient for evaluating the benefits of a better codec, as there are more subjective factors that are not reflected in the FR and THD measurements.

This should better simulate the subjective experience of most listeners when a codec is enabled. However, since both the transmitter and receiver must support aptX, you will be using the default sub-band coding more often than not.

The default SBC connection typically has more than ms of latency, which is noticeable when watching videos and may be severe enough to ruin your gaming experience. Regular aptX does somewhat improve latency due to its more efficient encoding algorithm than SBC. Regular aptX does somewhat improve the latency, but not as significantly as aptX-LL.

This makes the Backbeat Pro 2 and other headphones with the low latency codec good headphones for gaming and watching movies as long as both your Bluetooth transmitter and receiver support the aptX-LL. Codecs are the algorithms that compress data for easier and faster transmission.

Better encoding and decoding algorithms mean less lossy transmission which can help with audio quality. The subtle changes in audio quality due to a codec like aptX are negligible when compared to the reduced latency aptX Low Latency connection.

How satisfied are you with this response? This site in other languages x.Previously, these devices often had a reputation for providing average quality sound via Bluetooth, but aptX helps Bluetooth-enabled products overcome that barrier as it is designed to consistently deliver higher quality audio wirelessly. It is a strong, recognized brand in the consumer electronics marketplace, supporting virtually all major platforms including Android, Windows 10 and Mac OS.

Download PDF. A delay of less that 40ms can be achieved because aptX is a sample-based codec, and low latency can be achieved through efficient population of packets while maintaining transmission robustness.

As well as accepting a bit audio input, bit audio resolution is designed to be maintained by using an extra two bits in each of the four sub-bands of processing.

What this means in practice is that the codec is designed to automatically adjust to provide optimum audio quality or latency depending on what content is being played on the device while also taking into account the external RF environment to help robustness.

You could always try it? Is this the same as the ? It seems like it works according to folks who posted, but then again I'm not sure if the bluetooth chipset within the Intel is the exact same as the Can you confirm this? I did have an 3,5 year old zotac id64 mini pc, but it stopped working and the shop refunded me the purchase price that was more than the nuc I have an avantree pair of Aptx-LL headphones.

That device has different blinking patterns which shows what connection type is at play. But as I remember if you go to properties on the BT device it would use ms driver from something like before, after the aptx install the controller information is intel On the Avantree I think it was two blue blinks for aptx, and it was correct when I tested it before first trying these aptx drivers.

I find it very strange that Intel would not get a license for aptx for the nuc line. Problem is that it would probably apply to all intel capable cards. But Dell managed it. Keep in mind that the audio profiles are natively supported by Microsoft by the Operating System as well as the Bluetooth low energy support.

If it's in the A2DP spec, it's still often hard to determine what is preferentially used in Windows. The drivers often dictate which is used e. This is where the problem lies Some devices, such as the Avantree Audition Pro will blink alerting you to this, and I'm sure other lab testing hardware will tell you what the codec type is in use on bluetooth.

Please allow me some extra time to get some answers, this goes beyond my Intel Wireless knowledge since I support NUC products mainly. It is been really hard for me to get answers for your questions and I apologize for that and for the delay in getting back to you. This device allows Aptx-LL in Windows 10 via the bluetooth 4. Again, the responsibility lies on the manufacturer to provide drivers that support AptX-LL codec in Windows. I have the avantree product you linked, it's a 2-in-1 device that Windows will recognize as a regular "USB Audio device" with no bluetooth functions exposed.

Just aptx For more complete information about compiler optimizations, see our Optimization Notice. Register Help.Bluetooth is a flexible standard. It defines various profiles that operate on top of the Bluetooth networking protocol stack and implement specific services, such as hands-free communications.

Bluetooth devices each support a small subset of profiles, typically only one or two, according to their designated function. Bluetooth headphones and speakers implement the advanced audio distribution profile A2DP. The A2DP profile transports encoded audio streams from one device to another.

To guarantee compatibility between devices, any device implementing the A2DP profile needs to offer a common codec, SBC. One of those optional codecs is aptX.

Support for Bluetooth Aptx codec in Windows 10

Figuring out whether that is actually true is harder than expected. As this overview shows, the technical specifications of the base aptX code are similar to that of SBC. Different codecs can be very different in encoding efficiency, as are H. Fidelity can only be determined by double-blind listening tests. Unfortunately, nobody seems to have performed such listening tests in a scientific, reproducible manner at least I could not find any information.

Please let me know by commenting below if you know of any publications. Devices may select lower-quality modes to favor a stable connection over sound quality example: these Sony headphones. When watching a video, you do not want the audio to lag behind. In other words: the audio latency should ideally be small enough to not be noticeable. Unfortunately, that is often not the case. Bluetooth audio introduces significant latency, the exact amount of which depends on the codec as well as its implementations in the sending and receiving devices.

Most Bluetooth headphone reviews do not include latency measurements, with the notable exception of rtings. They even have a list with latencies for all the headphones they ever tested.Log inplease.

How to become an author. NET Knowledge Base. Log in Sign up. Bluetooth device manufacturers rarely disclose detailed product specifications, and Bluetooth audio articles on the Internet are contradictory and sometimes incorrect.

They do not tell about all the features, and often publish the same false information. Let's try to understand the protocol, the capabilities of Bluetooth stacks, headphones and speakers, Bluetooth codecs for music and speech, find out what affects the quality of the transmitted audio and the delay, learn how to capture and decode information about supported codecs and other device features.

AptX vs SBC – Which Codec Works Better?

Music via Bluetooth The functional components of Bluetooth are defined by profiles—documented features formalized in specifications. Bluetooth music is transmitted using a high-quality audio A2DP transmission profile.

The A2DP standard was adopted inand has not changed drastically since then. The profile standardize one mandatory codec—SBC, a low computational complexity codec created specifically for Bluetooth, and 3 additional codecs. One can also use vendor-specific codecs of your own implementation, not included into A2DP.

The time is divided into microsecond intervals, called slots. One of the devices transmits in even numbers of slots, the other—in odd numbers. A transmitted packet can occupy 1, 3 or 5 slots, depending on the size of the data and the transmission mode.

If the packet is big enough and more than one slot transmission mode is used, the data is carried out in even and odd slots until the end of the transmission. In one second you can receive and send up to packets if each of them occupies 1 slot and both devices continuously transmit and receive data.

Transfer rates of 2 or 3 Mbps for EDR found in announcements and on Bluetooth website are the maximum channel data transfer rate of all data in total including the technical headers of all protocols for data to be encapsulated into in two directions simultaneously. The actual data transfer rate will vary greatly. If more than one device is connected to the phone e.
