What you need to know about Sonys LDACWeve been talking a fair bit about Bluetooth audio lately, mostly because consumers and high end audio companies are making more noise about it than ever before. Be it wireless headsets, hands free ear pieces, automotive, or the connected home, theres a growing number of use cases for good quality Bluetooth audio.

Recombine Split Files' title='Recombine Split Files' />Fortunately, a number of companies have us covered with solutions that exceed the so so performance of out of the box Bluetooth solutions. Qualcomms apt. X already has a ton of Android phones covered, but multimedia giant Sony has its own high end solution called LDAC. This technology had previously only been available on Sonys Xperia range of handsets, but with the roll out of Android 8. Oreo the Bluetooth codec will be available as part of the core AOSP code for other OEMS to implement, if they wish. So heres everything that you need to know about Sonys LDAC Bluetooth codec. Higher quality Bluetooth audio. At the most basic level, LDAC supports the transfer of 2. Hz Hi Res audio files over the air via Bluetooth. The closest competing codec is Qualcomms apt. X HD, which supports 2. Hz audio data. Whats interesting about LDAC is that it comes with three different types of connection mode quality priority, normal, and connection priority. Each of these offers a different bitrate, weighing in at 9. So, depending on the type of connection available or the option you pick, there are varying levels of quality. Its clear that the slower bitrates arent going to give the full 2. Hz quality that LDAC boasts though, so keep that in mind. LDAC supports the transfer of 2. Hz Hi Res audio files over the air via Bluetooth, with three quality settings to choose from. Comparing bitrates is a questionable science, but it does give us a good idea about how much audio data each codec sends per second. High quality standard low complexity subband codec SBC clocks in at a maximum of 3. Qualcomms apt. X at 3. X HD is 5. 76 kbps. On paper then, 9. LDAC transmits a lot more data than any other Bluetooth codec out there. And even the low end connection priority setting competes with SBC and apt. X, which will cater for those who stream music from the most popular services. Jargon Buster Sample rate Hz the number of points of data per second in an audio file. You need two samples to accurately capture any frequency, so audio is sampled at at least twice the limits of human hearing approximately 2. Hz. Higher resolution file formats tend to be exported at 9. Hz or greater. Bit depth bit the number of bits saved for each audio sample. A higher bit depth records a signal more accurately. CD quality is 1. 6 bits, but high resolution files extend this to 2. Bit rate kbps usually measured in kbps or mbps. This is the amount of audio data transferred per second over Bluetooth. For uncompressed files, this is calculated by multiplying the sample rate by the bit depth. Sony is keen to make it clear that LDAC transmits up to 3x more data than SBC. However, thats only with the Quality preset, and bit rates are only part of the picture. The bigger question is how is this data being optimized. However, its impossible to say exactly how good LDAC is based on this data alone. Sony is keeping its LDAC secret sauce closely under wraps, but to properly put these numbers into context we need to know how the technology works on a lower level. So far, we can only say that, at its best, LDAC transmits a lot more data than other Bluetooth codecs. Increasing the transfer rate. Unfortunately, Sony hasnt published much in the way of in depth materials for how LDAC works. But scouring some older Japanese sources has yielded some details about what Sony is aiming to accomplish with LDAC, at least at its highest bit depth. There are two major parts to Sonys LDAC. First is achieving a high enough Bluetooth transfer speed to reach 9. LDAC makes use of Bluetooths optional Enhanced Data Rate EDR technology to boost data speeds outside of the usual A2. DP profile limits. But this is hardware dependant. The first stage is accomplished by using Bluetooths in house Enhanced Data Rate EDR option, which was introduced all the way back with Bluetooth 2. Nickey Huntsman Sleep. EDR speeds are not usually used by A2. DP audio profiles, but the spec is rated up to 3 Mbps. Although in reality, 1. Mbps is mostly achievable, with 1 Mbps being considered the minimum stable connection. Hence why Sonys LDAC sits just under this threshold at 9. I should point out that EDR is an optional part of even newer Bluetooth 4. So not every chip, and therefore not every phone, will necessarily support Sonys LDAC at the highest quality setting. Bluetooth 5 supports 2 Mbps low energy speeds out of the box, and is also backward compatible with EDR versions of Bluetooth, but again this higher speed is optional. LDAC, SBC, and apt. X share a common idea Now for LDACs compression technology, which appears to be an intelligent combination of lossless and lossy techniques to maximise sound quality at 9. And its all to do with varying the bit depth at different frequencies, which preserves significantly more data than psycho acoustic compression algorithms, such as those used by MP3. Those who are familiar with the human auditory system will be aware that hearing sensitivity begins to quickly fall off after 1. Hz, meaning that a lot of the data transferred in a 9. Hz file 4. 8 k. Hz of audible data per Nyquist Theory is incredibly difficult, if not impossible to hear. Furthermore, we also know that 2. Sonys LDAC doesnt go so far as to just chop out these very high frequencies, but it does reduce their bit depth at the quantization stage. In other words, theres more noise present at very high frequencies, but thats not a problem once we take into account the limitations of human hearing and the fact that we dont need anywhere near like as much detail at these very high frequencies. Normal PCM files have a set bit rate across all frequencies. But files can be compressed by reducing the bit depth at higher frequencies, with minimal impact on audio quality. Human hearing is most sensitive around 3 k. Hz, so reducing the level of detail at higher frequencies is an intelligent way to save on data size. The above basic example removes one bit of accuracy for each 6d. B loss in sensitivity, which would be imperceivable. How does Sony go about doing thisWell this translation from the article mentioned above is quite revealing LDAC does not divide the subband partial band but goes directly to frequency conversion. Paxton Net 2 Lite'>Paxton Net 2 Lite. So, LDAC appears to be using a somewhat similar technique to Qualcomms apt. X and even the standard SBC, where the original PCM audio file is split up into multiple frequency bands each with different bit depths. Again, the higher frequencies use smaller bit depth and therefore suffer from more noise, so technically this is somewhat lossy. However, this is a worthwhile data saving as it doesnt affect listening quality nearly as much as culling data using psychoacoustic techniques. Sub band coding is used in a variety of codecs, including SBC, MP3, AAC, apt. X, and LDAC. Many codecs use this for psychoacoustic masking, but apt. X and LDAC only adjust the bit depth in line with hearing sensitivity. There are some notable differences between LDAC and apt. X though. While apt. X has just four sub bands, LDAC appears to max out at 1. AOSP librarys header file.
