Audio codecs for the TriMedia platform

Streaming Networks offers a set of audio codecs for the TriMedia platform. These codecs are optimized implementations of ITU-T recommendations. These codec libraries are available with the TriMedia streaming interface (TSSA).
G.711
Standard codec for telephony applications. Implements A/mu-law companding.
G.722
Sub-band ADPCM for wide-band (7-KHz) speech or audio. Compression achieved by frequency-domain splitting of the audio signal in low and high bands with the QMF filters, and applying adaptive PCM to each band.
G.723.1
Belongs to the state-of-the-art ABS speech codecs based on variations of CELP, with LPC and pitch-prediction. Dual rate.
G.728
Belongs to the state-of-the-art ABS speech codecs based on variations of CELP. Features a backward-adaptive version of CELP to achieve low delay.
G.729A
Belongs to the state-of-the-art ABS speech codecs based on variations of CELP, with LPC and pitch-prediction. The G.729A is interoperable with its higher-complexity version, the G.729.
