Bluetooth Low-Energy Profile Creates New Opportunities – in the areas of consumer electronics, health and medical, smart-home, and sports and fitness markets. Called Bluetooth Smart, this part of the Bluetooth 4.0 spec exists in over ten million peripheral devices shipped last year. The technology extends battery life by more than ten times compared to higher-power Bluetooth. Size of devices can also be reduced thru use of lower-power button-cell batteries instead of AA batteries. The technology will soon appear in wireless keyboards. Makers of Android smartphones are implementing Bluetooth Smart in select models, and one firm as two smartwatches, which communicate with Android phones to display text messages, email headers, caller ID data, and can control music playback features.
HDTT to Offer 384K/24bit Downloads – Some titles in the High Definition Tape Transfers catalog will soon be available at 24/384 resolution. Some experts claim that at 192K sample rate, an anti-aliasing filter is still needed, which can cause phase shift, distortion and other byproducts that may impact audible frequencies. An anti-aliasing filter is not needed with 384K files. It is felt that all lower sampling rates sound more “digital” than 384K sampling due to the pronounced effects of anti-aliasing filters. The 384K files can be easily converted to 128 times DSD with virtually no signal loss.
