Audio Bend - Unable to quantize correctly?

This message was edited 1 time. Last update was at 01/11/2011 01:21:16

I've tried all ways that I can think of, but is unable to successfully quantize audio.

In this case my picture shows the kick drum and as you can see the audio lines up perfectly to suddenly not line up and then come back.

Is this due to erroneous workflow, or is this a bug?

EDIT: I've also included the snare that shows the same problem....

Could you attach the audio file here?

Thanks

First post is now updated with audio...

Yes, it's a bug. The problem is is that for quantizing audio, a fixed range of 60% is used.
That's why markers that are too far away from the grid lines are not "catched".

It should actually use the range parameter from the quantize panel (default 100%, which would quantize all markers).

Tnx for listening!

Is this related? - If I single-quantize (quarter notes) the snare track it seems to pull the snare to beat 1 & 3 instead of 2 & 4.

How would I handle such problem? Is there a way to define the first beat?

You might get better results if you group the tracks. The bend markers from both tracks are then combined and quantized together.
(This also avoids phase problems with the in a multi-microphone recording, because all tracks are manipulated in the same way).

However, I see that the quantize function needs to be improved for such an off-beat scenario, it currently prefers the bar start positions too much...

Tnx for sharing!

In the mean time I try to tab-to-transient. However I'm unable to find the key-command to insert a bend marker. Using the mouse I tend to miss the spot and it also slows the workflow...

During those test, at times, undo was unable to remove bend markers I created with the mouse.

Since audio-Q/transient detection usually never is 100% correct and, as you said, you want to be phase locked there should exist some way to insert bend makers manually for combined tracks.

Does this make sense to you?

Yes, a key command to insert a marker at the play cursor position makes sense.

This might be a redraw bug that we fixed yesterday. In that case the marker was deleted, but the graphics just not updated.

On grouped tracks, an inserted marker gets added on each track.

Ooops, never noticed that one

Tnx Maik!
