Vidosystem offers implementations of G.729 audio codec. The implementation is in acm driver of windows. Fully compatible with Windows RTC protocol (SIP Protocol).

G.729 is an audio data compression algorithm for voice that compresses digital voice in packets of 10 milliseconds duration. It is officially described as Coding of speech at 8 kbit/s using conjugate-structure algebraic-code-excited linear prediction (CS-ACELP).

Because of its low bandwidth requirements, G.729 is mostly used in Voice over Internet Protocol (VoIP) applications where bandwidth must be conserved. Standard G.729 operates at a bit rate of 8 kbit/s, but there are extensions, which provide rates of 6.4 kbit/s (Annex D, F, H, I, C+) and 11.8 kbit/s (Annex E, G, H, I, C+) for marginally worse and better speech quality, respectively

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. for more information about VidoG729 ACM Codec press here!
