I would like to raise the issue of sloped stretch markers again.
Sloped stretch markers can potentially be used to protect transients when stretching drums and other material with strong transients: If each stretch marker starts at 1.00x, the transient should be minimally affected.
Unfortunately, stretch markers that slope downwards still give echoey artefacts.
As an example, here is a drum track that I am trying to slow down from 120bpm to 77bpm. 1) Place stretch markers before each transient, using Transient optimized mode, 2) stretch item, 3) convert all stretch markers to sloped ones, and 4) render:
The transient before the start of measure 2 is destroyed, but surprisingly, the transients at start of measure 3 all stretched OK, even though they are closer together.
And zoomed in at the stretch marker:
Strangely, I get the least artefacts when I use a very long stretch marker fade length of 200ms. Shorter fade lengths such as 2.5ms lead to terrible smearing of transients when downward sloping stretch markers are used.
Are these issues with sloped stretch markers something that can be solved, or do they fall into the "just live with it" category?
