again. An attack setting of about 10 milliseconds will delay the onset of compression long enough to preserve the attack transients in guitar, bass or drums while allowing the sustain portion of the sound to be compressed. Longer release times are generally used to reduce the so called "pumping" effect as the compressor turns on and off. Don't make the release time too long, however, or the compressor won't have time to recover for the next pluck or hit. In general, the attack and release controls are used to smooth out the action of the compressor, but they can also be used to create special effects. The Pre-Delay parameter lets the level detector "look into the future" up to 4 milliseconds in order to anticipate upcoming peaks in the signal. This is accomplished of course, by inserting delay into the signal path. This lookahead technique allows the use of slower attack times without missing signal peaks. This parameter is especially effective on drums and percussion. The Input Meter allows you to monitor the strength of your input signal. Always try to boost the signal before the compressor if you can. The Compression Meter shows the amount of gain reduction being applied. Since this meter displays how much the gain is being turned down, the meter moves from right to left, instead of left to right like a normal meter. 5 - Effects Core Effects Descriptions Parameter Threshold Ratio Post Gain Attack Time Release Time Pre-Delay Description Threshold sets the input signal level above which dynamic range compression takes place. Everything above the threshold will be brought down in volume. Range: -60dB to +12dB Sets the ratio of input signal level to output signal level, or "how much" compression will be applied. Range: 1:1 to ×:1 Amplifies the signal after it has been compressed to bring up the volume. Range -60dB to +60dB Controls how quickly the gain is turned down after the signal exceeds the threshold. Range .1ms to 500ms Controls how fast the gain is returned to its normal setting after the signal has fallen below the threshold. Range: 50ms to 3000ms Allows the use of slower attack times without missing signal peaks. Range: 0ms to 3 ms Input Meter Gain Reduction Meter Allows you to monitor the strength of the input signal. Shows the amount of gain reduction being applied. E-MU PCIe Digital Audio Systems 69
