FLAC*
This encoder compresses audio data using a lossless algorithm. This means that the audio extracted from the
decoder is iden cal to the audio input to the encoder, with no coding ar facts. FLAC typically removes 30-40% of
the network data compared to Linear PCM, but the actual data rate is variable and is based on the complexity of
the coded audio.
Using FLAC over Linear PCM typically results in a slightly higher (5 ms) overall delay.
G.722
This is a well known 7 kHz (medium fi delity) algorithm used in some VoIP telephones and codecs. It is provided for
compa bility purposes, and is not considered a superior algorithm for audio codecs.
OPUS
A newer o ff ering that combines low delay and low network u liza on. Opus is included primarily for compa bility
with so phone apps, and Internet connec ons using WebRTC (see Technotes about WebRTC on the Comrex
website). Special CBR modes are o
ff ered for compa bility with Tieline products—avoid these in other applica ons.
Due to its versa lity in audio quality and low networking drain, Opus is the default pro fi le for Comrex codecs.
*Linear PCM and FLAC are only supported for CrossLock connec ons on devices running fi rmware version
4.3-p4 or higher.
