# Template:DelayFeedbackParameter

 Control Type Has Sub-chain? Sub-chain Parameters Fader Scale Gain/Bias yes gain (-3 to 3) bias ($\displaystyle -\infty$ , -36dB to 0dB) logarithmic
This value determines how much of the audio in the delay line to mix with the delay's input. A value of 0dB means that the old and new are summed together as-is and will eventually cause the contents of the delay line to grow so loud that it will clip when it arrives at the DAC. A value of $\displaystyle -\infty$ means that the new material completely replaces the old material in the delay line. Anything less than 0dB will cause the old material to slowly fade away with each (delayed) repeat. The following graph summarizes the number of repeats required to fade to 10% of the original captured amplitude vs the feedback amount:
