So what exactly is LDAC, and what benefits does it confer? LDAC is a proprietary wireless audio codec developed by Sony. The codec is different from older Bluetooth streaming technologies in that it uses a combination of lossless when possible and lossy compression to deliver high-resolution audio.
Despite the marketing, only the higher bitrate of kbps qualifies the codec as a truly wireless, high-resolution audio solution. Qualcomm introduced aptX HD also known as aptX Lossless in to enable higher bitrate streaming of kbps on compatible Bluetooth headphones. While Sony developed the technology and continues to push it in its own products, the LDAC encoder is open source. This has led to it being included in many more products, including the Android 8.
Audio companies offer numerous variants—or codecs—of Bluetooth, and some people claim that a certain codec will improve Bluetooth sound quality. But those differences are hard to quantify and harder to hear. If you try different Bluetooth codecs, the difference will be small and possibly inaudible. You can test this yourself using my online Bluetooth blind test. In audio devices, the key difference in Bluetooth implementation involves which audio codec they use. Typically, they reduce the 1,kilobits-per-second data rate of CD-quality audio to around kbps.
The discarded data represents audio that the human ear is less likely to detect, such as a soft sound in the presence of a similar but louder sound. Some codecs allow higher data rates, thus requiring less compression and offering the potential for better sound.
If you use these two things along with a wireless speaker or headphones that also support AAC, Bluetooth will not impact the sound quality. Check Price. Name: Subject: Message:.
