想請教陳 sir 
Telarc 是否新舊版有別，睇過外國有玩absolute polarity 的燒友稱舊版 Telarc (80年代)是negative, 2000年後有SACD 時變了 positive, 還用電腦做了波形對比，看圖真的是相反的
1) You can look at the shape of the waveform during a particularly loud, bright, raspy "brassy" trumpet or trombone passage. The waveform of a brass instrument is typically asymmetrical. If you look at the waveform in the Cubase software (or on an oscilloscope), you will see that the positive-going half of the waveform has a sharp, spiky appearance, and the negative half is more "rounded" and of slightly lower amplitude. (The brasses in the new Telarc hybrids are definitely "spikes up"!)
這段是他的分享，更令我更明白為甚麼要分 |
