Talk:Bandwidth extension

Original Research?
I have included a few additional references for bandwidth extension of speech. The topic is not original research. In fact, the concepts of bandwidth extension are used in standardized audio coders today. It is an important field of study that should be further expanded.Cepstrum 23:27, 9 November 2007 (UTC)

This article appears to have been written by the author of the referenced material and linked to related pages as a self-promotional maneuver. The article contains little or no content explaining the theory and in my opinion it should be improved or removed.--Ron E 03:22, 14 July 2007 (UTC)
