Has anyone heard anything about any head units coming out soon that have the APT-X lossless Bluetooth codec? For hi-def wireless audio from our phones to the car stereo?
==========================
What is APT-X?
It's Bluetooth for "Audiophiles".
APT-X Lossless supports high-definition audio up to 96 kHz sampling rates and sample resolutions up to 24 bits.
If I had to guess, normal A2DP Bluetooth might sound as good as a 96kbps MP3 file. While APTX Bluetooth sounds as good as a 320kpbs MP3. Essentially, to the trained ears it is a HUGE difference in sound quality.
