splitting warped but unstretched clips with loop on and off;
In all cases, output is rendered and compared with the output of an unsplit version of the
same source. Phase cancellation testing of the two les conrms that they are identical.
26.3 Non-Neutral Operations
Procedures in Live that will cause a change in audio quality are referred to as non-neutral
operations. Users can be guaranteed that using these operations will cause at least some
change to the signal. Applying non-neutral operations to les imported into Live ensures
that the imported audio will differ from the les saved on disk. Applying non-neutral
operations to les being exported from Live ensures that what you hear during realtime
playback will be different from what will end up in your new le.
Non-neutral operations include:
26.3.1 Playback in Complex Mode
The algorithm used in Complex Warp Mode is an entirely different technology from the
algorithms behind Beats, Tones and Texture modes. Although Complex Mode may sound
better, particularly when used with mixed sound les that are comprised of many different
kinds of audio material, it is never neutral  not even at the original tempo. Because of this,
and because of the algorithm's increased CPU demands, we recommend using it only in
cases where the other Warp modes don't produce sufcient results.
26.3.2 Sample rate conversion/transposition
Sample rate conversion (during both real-time playback and rendering) is a non-neutral
operation. Playback of audio les at a sample rate that is different from the rate set in
Live's Preferences window will cause signal degradation. Transposition is also a form of
sample-rate conversion, and thus also results in non-neutral behavior.
