CHAPTER 30. AUDIO FACT SHEET 494
30.2.8 Bypassed Effects
Bypassed effects in Live are removed from the signal ow. This is true for both Live's built-in
effects devices and third-party VST and AU plug-ins. Consequently, audio at the output
of a bypassed effect is identical to the audio at the input. Please note, however, that
effects devices with parameters that inherently require delay (e.g., the Look Ahead settings
in Compressor) will still introduce this delay when bypassed, in order to maintain automatic
delay compensation with the rest of the project. In most cases, the effects of this behavior
will be completely inaudible.
The neutrality of bypassed effects is tested by loading one instance of each of Live's effects
devices into an audio track, deactivating them, and then rendering the output of the track.
The rendered le is then compared to the rendered output of the same track with no loaded
devices. Phase cancellation testing of the two les conrms that they are identical.
30.2.9 Routing
The routing of signals within Live is a neutral operation. The signal at the routing destination
will be identical to the signal at the routing source. It is important to note that Live's exible
routing architecture allows for a variety of scenarios, including routing from before or after
any track's effects or mixer and tapping the output of individual sample slots within the
Impulse instrument. In these cases, it is likely that the signal heard at the output point
will be different from the signal heard prior to routing, because it has been tapped before
reaching the end of its original signal chain.
30.2.10 Splitting Clips
Clips which are already neutral will remain neutral after splitting. Splitting only affects
playback position within the sample, and has no effect on the sample data itself. Playback
across a split boundary is seamless and sample-accurate.
The neutrality of clip splitting is tested under a variety of conditions:
 splitting unwarped clips with loop on and off;
 splitting warped but unstretched clips with loop on and off;
