我的定制耳机响应频率只到20kHz,音响高音喇叭也是只到20kHz。。。。。。lz能否指点一下你是啥设备发出高达96kHz的声音的?
既然所有的设备都是用现有的科学制造出来的并且按照现有的科学理论严格工作的,为啥相信 ...
从你贴的那篇文章里看到的:
This paper presented listeners with a choice between high-rate DVD-A/SACD content, chosen by high-definition audio advocates to show off high-def's superiority, and that same content resampled on the spot down to 16-bit / 44.1kHz Compact Disc rate. The listeners were challenged to identify any difference whatsoever between the two using an ABX methodology. BAS conducted the test using high-end professional equipment in noise-isolated studio listening environments with both amateur and trained professional listeners.
In 554 trials, listeners chose correctly 49.8% of the time. In other words, they were guessing. Not one listener throughout the entire test was able to identify which was 16/44.1 and which was high rate [15], and the 16-bit signal wasn't even dithered!
