請問一下不同 audio gain method 的差別是什麼?
某轉檔軟體的 audio gain 設定除了 auto/manual gain 以外還有下面這些選項可調.....
引用:
|
The −n option normalises the audio to 0dB.
|
引用:
|
Given the −e option, the levels of the audio channels of a multi-channel file are ‘equalised’, i.e. gain is applied to all channels other than that with the highest peak level, such that all channels attain the same peak level (but, without also giving −n, the audio is not ‘normalised’).
|
引用:
|
The −B (balance) option is similar to −e, but with −B, the RMS level is used instead of the peak level. −B might be used to correct stereo imbalance caused by an imperfect record turntable cartridge. Note that unlike −e, −B might cause some clipping.
|
引用:
|
−b is similar to −B but has clipping protection, i.e. if necessary to prevent clipping whilst balancing, attenuation is applied to all channels. Note, however, that in conjunction with −n, −B and −b are synonymous.

請問有沒有人對錄音技術比較了解....... 能夠正確解釋不同選項之間的用途, 意義跟差異在哪?........ |
