Why is PCAU audio so much better?
This is a long answer, but there are lots of reasons. Conventional Program Channel Units use J.41 audio processing. Although adequate when first developed 20 years ago, J.41 cant reproduce the low frequency and mid band punch typical of modern CDs, and exhibits noticeably more background hiss. The alternative to antiquated J.41 audio is the revolutionary Audio Processing Technologys apt-X algorithm found in the Pulsecom/APT Program Channel Access Unit, or PCAU. Heard world-wide in digital movies and used by flagship radio stations like the New York Times WQRX, the apt-X has set a new standard for audio quality for a number of very specific reasons.
