Title: Call for ATRAC SP (Type-R) test recordings
Post by: Serge Smirnoff on 2010-05-08 14:59:54
Hi All,

SoundExpert starts new experiment which could be interesting for HA forumers. It concerns time warping procedure developed inside SE. Details are in SE news article (http://soundexpert.org/news/-/blogs/call-for-atrac-sp-type-r-test-recordings).

We chose Sony Insider forum (http://forums.sonyinsider.com/index.php?showtopic=25460) as the main place for discussing and covering the experiment because the experimental candidate is ATRAC SP (Type-R) hardware codec and we need help from people with MD (Type-R) devices. Nevertheless, we would be glad to receive feedback from HA people as well.

Serge.

First two submitted recordings appeared on Analysis of submitted ATRAC SP (Type-R) recordings (http://soundexpert.org/news/-/blogs/analysis-of-submitted-atrac-sp-type-r-recordings) page. One belongs to Lee Keywood who originally proposed this codec to SoundExpert and another one - to Numinos from MiniDisc Forum (http://www.minidiscforum.de/forum/viewtopic.php?f=3&t=20829&start=0). Time warped versions and artifacts signals are available for both.
