Introduction
In this tutorial we learn how to install celt051 on CentOS 8.
What is celt051
CELT (Constrained Energy Lapped Transform) is an ultra-low delay audio codec designed for realtime transmission of high quality speech and audio. This is meant to close the gap between traditional speech codecs (such as Speex) and traditional audio codecs (such as Vorbis). The CELT bitstream format is not yet stable, this package is a special version of 0.5.1 that has the same bitstream format, but symbols and files renamed from ‘celt*’ to ‘celt051*’ so that it is parallel installable with the normal celt for packages requiring this particular bitstream format. celt051 0.5.1.3 15.el8 x86_64 63 k celt051-0.5.1.3-15.el8.src.rpm appstream An audio codec for use in low-delay speech and audio communication http BSD CELT (Constrained Energy Lapped Transform) is an ultra-low delay audio codec designed for realtime transmission of high quality speech and audio.
