G.722.1 Wideband Audio Coder by Adaptive Digital Technologies, Inc.

Audio and Voice Solutions

Product Description

The Adaptive Digital Technologies G.722.1 Audio Coder is an implementation of the ITU G.722.1 standard.

Adaptive Digital’s G.722.1 coder is a high quality low-complexity algorithm that provides an audio bandwidth of 50Hz to 7kHz (to 14khz with Annex C), operating at a bit rate of 48 kbps (Annex C), 24 kbit/s or 32 kbit/s or 16 kbit/s (Not available in Annex C).  This wideband, audio coding algorithm can be utilized for services such as video conferencing, teleconferencing, and Internet streaming applications, and is recommended for use in hands-free applications such as conferencing where there is a low probability of frame loss. 

The G.722.1 audio coder encodes 16 kHz and 32khz sampled audio signals for transmission over 16, 24, 32 and 48 kbps channels, and provides 7 kHz /14khz of audio bandwidth.

Features Include:

• Functions are C-callable
• Multi -Channel Implementation.
• Completely re-entrant (Channel can interrupt any Channel, any time)
• Can be integrated with echo cancellers, VOX and tone detection/regeneration.
• Includes Frame Loss Concealment Algorithm

Supported by ARM processor-based devices
