Warping Re-Imported Stems Ruins Playback Quality?

[edit_machine]

Hi, I recorded some vocals into a live clip, picked my favorite 8 bars sections and lined them up into a few clips decending on a track. All these clips are set to Warp but since I havn't changed the tempo they sound completely natural and unaffected.

I rendered the vocal track and sent it into another DAW that I like to use for audio comping / editing. I also rendered a summed guide track of all the instrument parts of the song to use as a reference in the other DAW. I set the other DAW to the exact tempo of the live Project and line the vocal track and the guide track up on the grid. I comp my favorite takes together and render the new files so I can take them back into Live. I cut them into 8 bar sections since thats the length of my scenes in the live project. They are each exactly the same length and live instantly recognized them as 8 bar loops at the proper tempo when they are imported. But they sound funny when they play back (a sort of aliasing, pitch shifting quality).I checked the Launch, Sample, and Envelope pages on both the old clips and the new clips and the settings appear to be identical.

Now, if I set all these new clips to not warp or loop, and use follow actions to make them follow the arrangement (which is a decending pattern on each track in the session view), they sound fine, everything lines up and sounds natural. I can un-mute the original vocal track now and hear that they are in phase with the new ones.

So what I seem to have is some trouble setting the warp function on the new clips properly. It seems that they should sound natural and unaffected with warping on since their tempo has never changed and they are the same sample rate as the original audio clips, which sound natural with their warping on. I don't have this problem with any of the loops from my sample libraries, including vocal loop samples from sample libraries.

I have checked the sample rates of all sessions and files involved, everything is and has always been 48k 24 bit, so it doesn't seem to be a sample rate conversion problem. Any insight into this mystery would be appreciated.

Use repitch or beats mode the second time you warp them, as it will not affect the audio at all at the same tempo. Otherwise, warping will always have some effect on the audio, especially complex mode.

Hi,

Any warp mode should be neutral when the clip has the same tempo as the Live set, but Complex and the new Live 8 Complex pro. So you can use Beats, Tones and Texture as well as Repitch.
