Our in-world AtmoSphere sound previews are limited to ten seconds and the SL Marketplace does not provide such a feature at all.
increasing the preview length is something that we have wanted to do for quite some time and we are working to bring longer sound previews to this web site. This is an ongoing effort to bring these product previews online for easy browsing during the next few weeks.
The example below shows how the AtmoSpheres will be categorized along the same lines as our in-world vendors in Skybeam. The sound previews are extended from ten seconds to approximately thirty seconds in length. The purchase process is maintained through the SL Marketplace as normal.
More announcements to follow!
