Adaptive Digital is a developer of voice algorithms, soft-chip solutions, and VoIP Engine software for VoIP and traditional telecommunications systems and applications. Our expertise is in the development of solutions that maximize voice quality as well as channel density.

VoIP Engine™ is at the core of our ARM-based VoIP applications, it is a software engine package that handles all the voice processing from PCM to Packet and back. Its intended use is in VoIP enabled handsets or desktop phones.

G.PAK™, the core technology behind our turnkey solutions, is a VoIP application that runs on a TI DSP or SOC that handles the complete data flow between the TDM and Packet interfaces.

Adaptive Digital’s Algorithm Library Includes:

Voice Quality Algorithms: Echo Cancellation – G.168 Line, Network, & Packet, G.168Plus™ Packet EC, Acoustic Echo Cancellation (AEC), AEC G2 (mobile devices) & HD AEC G4 (NB/WB), Noise Reduction, Noise Suppression, and Comfort Noise Generation.

All of the ITU G.XXX vocoders and many of the ETSI and 3GPP compression algorithms.

HD Audio/Voice algorithms: HD AEC, HD Conferencing, G.722, G.722.1, G.722.2 (AMR-WB), Speex

Telephony algorithms: Tone Detect and Suppress, DTMF, AGC, Arbitrary Tone Detect, R1/R2 Detect, Voice Activity Detection, Tone Relay, and High Density Conferencing (NB/WB)

Military and Defense codecs: MELP/MELPe, CVSD, LPC, G.729D

Encryption algorithms: AES, SRTP

Modem software: Caller ID, T.38 Fax Relay, V.xx (21, 27, 29, 22Bis, & 32Bis), Modem Relay, and G.165 detect
