直射= 10 m
反射= 7 + 12 =19m
距離差= 19 - 10 = 9m
假設聲音每秒速度是 330公尺
時間差= 9 / 330 = 0.027 sec = 27 ms
請依此來計算 B點的時間差.

簡短說明 Pre Delay
舞台上有A、B兩支樂器，A點的直射音和一次反射的時間差計算如下：
直射= 10 m
反射= 7 + 12 =19m
距離差= 19 - 10 = 9m
假設聲音每秒速度是 330公尺
時間差= 9 / 330 = 0.027 sec = 27 ms
請依此來計算 B點的時間差.

動態的論戰!
More dynamics = Better sounding MP3s and radio broadcasts!
One thing is for sure: a song with DR14 which is sent through the processing chain of a radio station sounds just as loud as a song with DR6. In addition, it undergoes substantially less damage from the station's compressors!
On the other hand, the inherent loudness relationships (dynamics) in an already over-compressed DR6 track will be degraded and distorted through these processes. From a commercial point of view, there is no reason to over-compress CDs. In addition, unwanted audio artifacts resulting from levels that are too high or distortion in general is no longer a problem when encoding MP3s with DR14 music; musical enjoyment is significantly higher when listening to MP3s! Pleasurize Your Music!
