Vidosystem offers implementations of G.729A audio codec. The implementation is in acm driver of windows. Fully compatible with Windows RTC protocol (SIP Protocol).G.729 is well known as best codec ever. G.729 will give best audio quality over voip. Based on renowned Code Excited Linear Prediction (CELP) coding model, G.729 is a low rate ITU-T standard with toll quality in ip telephony.G.729 only use 8 kbps and operates at 10 ms frames, allowing low rate stream with minimal delay. This advance makes G.729 as the audio codecs for carrier grade voip network.
Vidosystem offers G.729 annex A: Digital Simultaneous Voice Data a low complexity version of G.729 standard. G.729A is the best complexity/quality ratio. Developed with compliant of ITU-T standard specification and Windows acm driver. This codec is fully compatible with Windows RTC 1.2 and above with any samples and frame duration.
