DynamicRangeController Level, Compression, Expansion Category Compresses or expands the Input’s dynamic range as a function of the SideChain’s amplitude envelope. The Input and output levels will be the same except when the SideChain amplitude envelope crosses the specified Threshold. If Compressor is selected, the Input will be attenuated whenever the SideChain amplitude exceeds the Threshold. If Expander is selected, the Input amplitude will be boosted whenever the SideChain amplitude falls below the Threshold. You specify the Ratio of the input to the output amplitude. Typical uses include: Limiting (compression with a very large ratio and high threshold), Gating (expansion with extremely small ratio and low threshold), Ducking (set attack and decay to 1 or 2 seconds, put the signal you want to duck in an out at the Input and put the controlling signal at the SideChain, and also mix the SideChain with the output of the DynamicRangeController) , making short percussive sounds seem louder (compress, then increase the overall gain), and smoothing out extreme changes in amplitude (particularly useful when recording to media with limited dynamic range, such as cassette tape or videotape). SideChain The amplitude envelope of this signal affects the amplitude envelope on the Input. Whenever the SideChain’s envelope crosses the Threshold, the Input’s dynamic range will be either compressed or expanded. Input This is the signal whose dynamic range will be compressed or expanded. Type Choose Compressor to compress all amplitudes above the threshold to a narrower dynamic range. Choose Expander to expand the dynamic range of all amplitudes below the threshold to a wider dynamic range. Ratio This is the ratio of the Input amplitude to the output amplitude. For compression, it should be greater than 1. For expansion, it should be less than 1. (This only affects the Input when the SideChain crosses the Threshold). Threshold This is the point at which a graph of Input to output level changes from a straight line to a curved line. In compression, the Input is unchanged when the SideChain amplitude is below this threshold. When the SideChain amplitude exceeds this threshold, the Input is attenuated. In expansion, the Input is unchanged when the SideChain amplitude is above this threshold. When the SideChain amplitude falls below this threshold, the Input is boosted. 250
AttackTime Relates to how quickly or slowly the output amplitude will be modified whenever the Threshold is crossed. This controls how quickly the envelope follower on the SideChain reacts to increases in the SideChain’s amplitude. ReleaseTime Relates to how quickly or slowly the output amplitude returns to normal whenever the Threshold is crossed. This controls how quickly the envelope follower on the SideChain reacts to decreases in the SideChain’s amplitude. Delay Typically set to equal to the attack plus the decay time. This is to compensate for the delay introduced by the envelope follower on the SideChain. Gain Besides changing the relative levels within the signal, compression and expansion usually change the overall level of the output signal as well. Use Gain to adjust the overall level up or down. 251
