實用工作流程
- (繁中)Record instruments and 人聲 with peaks at -12 to -18 dBFS. Use a preamp with a clean gain stage.
- 在載入任何外掛之前,使用輸入增益/修剪將每條通道調整至 -18 dBFS RMS。
- (繁中)After each 外掛, make sure the output level matches the input (unity gain).
- (繁中)Use channel faders at unity to set the mix's relative balance, not to fix gain.
- (繁中)Keep the 母帶匯流排 peaking at -6 dBFS or lower while 混音.
- (繁中)匯出 the mix with -3 to -6 dBFS of 餘裕 for the 母帶 engineer.

常見 問題
- (繁中)What's the ideal 錄音 level in a DAW?
- (繁中)Record with peaks at -12 to -18 dBFS. Modern 24-bit audio has 144 dB of 動態 range, so 錄音 at a lower level doesn't reduce quality. It leaves 餘裕 for unexpected peaks and prevents clipping.
- (繁中)Should I use a limiter while 錄音?
- No. Never use a limiter while 錄音. 限製ers destroy transient detail and make editing harder. If levels are too high, lower the preamp gain or move the microphone farther from the source.
- (繁中)Does gain staging matter with 32-bit float?
- (繁中)32-bit float 處理 inside the DAW prevents internal clipping, but 外掛 inputs and the 母帶匯流排 still need proper levels. Analog-modeling 外掛 especially expect -18 dBFS for optimal sound.
- 為什麼我的混音明明沒有削波(clipping)卻聽起來失真?
- 沒有削波卻出現失真,通常是由以下原因造成的:模擬類外掛接收到的訊號過熱、取樣間峰值(inter-取樣 peaks)超過了 0 dBFS,或者多個飽和外掛累積產生的諧波飽和。請檢查各個外掛的輸入電平。
- 什麼是 -18 dBFS,為什麼它是標準?
- -18 dBFS(RMS)相當於模擬裝置上的 0 VU。它代表了最佳工作電平,在這一電平下轉換器和外掛擁有最好的信噪比和最少的失真。
- 如何修正錄製得過響的混音?
- 在每條通道的最前端使用一個 trim/增益外掛,將電平降低適當的量。不要只是拉下推子(fader),因為訊號鏈後面的外掛接收到的仍是過熱的訊號。
