The AirPods Professional 2 sound higher than the first-gen Apple Professional earbuds, and their noise cancellation has additionally been refined.
So, how did Apple enhance issues on the audio output facet if it did not make optimizations on the audio information packet transmission? In response to Andersen, Apple’s engineers fine-tuned the engineering. Particularly, the group tweaked the airflow channel contained in the AirPods Professional 2 to spice up the audio readability in any respect ranges, whereas streaming audio on the identical decision over the identical AAC codec because the first-gen AirPods 2.
Will Apple tweak its strategy to codecs and delivering lossless audio over Bluetooth down the street? Andersen did not provide a concrete reply, besides to tease that “Apple is all the time open to alter.” To recall, Apple added Lossless functionality to the whole Apple Music catalog by creating its personal lossless audio compression know-how known as Apple Lossless Audio Codec (ALAC), which delivers an output ranging between 16-bit/44.1 kHz (CD High quality) and 24-bit /192kHz.
Sadly, Lossless Audio cannot be loved over Bluetooth. The iPhone or iPad’s built-in audio system can ship that have, or by way of wired earphones. However to actually get pleasure from music over the 44kHz vary, you may want a digital-to-analog converter or DAC. Qualcomm made important strides with its aptX Lossless Audio codec, which guarantees CD-quality sound over Bluetooth wi-fi connection by streaming 16-bit/44.1kHz audio over a peak 1,200kbps bitrate.
