Speex

Speex is an audio compression format designed for speech and also a free software speech codec that may be used on VoIP applications and podcasts. It is based on the CELP speech coding algorithm. Speex claims to be free of any patent restrictions and is licensed under the revised (3-clause) BSD license. It may be used with the Ogg container format or directly transmitted over UDP/RTP.

The Speex designers see their project as complementary to the Vorbis general-purpose audio compression project.

Speex is a lossy format, meaning quality is permanently degraded to reduce file size.

The Speex project was created on February 13, 2002. The first development versions of Speex were released under LGPL license, but as of version 1.0 beta 1, Speex is released under Xiph's version of the (revised) BSD license. Speex 1.0 was announced on March 24, 2003, after a year of development. The last stable version of Speex encoder and decoder is 1.1.12.

Xiph.Org now considers Speex obsolete; its successor is the more modern Opus codec, which surpasses its performance in all areas.

Mossberg 930

The Mossberg 930 is a 12-gauge semi-automatic shotgun designed by O.F. Mossberg & Sons.

The Mossberg 930 is one of the most popular automatic shotguns, used by hunters and skeet-shooters often.

Design

The Mossberg 930 is gas operated, which means that some of the hot gases from the burning gunpowder are used to push a piston that operates the action, ejecting the spent hull and chambering a fresh shell. This gas action reduces the recoil felt by the shooter. Like other Mossberg shotguns, this shotgun has an ambidextrous safety that is located on the rear of the receiver. The Mossberg 930 takes 2¾" or 3" shells and can be accessorized with shell catchers, Picatinny rails, special muzzle brakes for door breaching, etc.
