How does Siren 14 technology compare to other “free” audio codecs?
Other “free” audio codecs that we are aware of either make use of technology on which the patents have expired (principally PCM and ADPCM codecs), in which case they require far higher bit rates (typically at least 128,000 bits/s) to approach Siren 14 technology’s performance, or they use techniques about which there is dispute as to whether they infringe on patents held by third parties. To our knowledge, Polycom’s Siren technology is the only modern state-of-the-art audio coding technology offered on royalty-free terms.
