Montbonnot, France — Digigram announced that it has added support for the Opus encoding algorithm to the company's IQOYA *CALL and IQOYA *CALL/LE IP audio codecs. Opus offers a low latency audio encoding option for compatibility with a wider variety of IP audio codec hardware and networks.
Digigram's IQOYA *CALL and the company's lower cost IQOYA *CALL/LE also offer support for most current encoding algorithms. In addition to Opus, the IP audio codecs support Fraunhofer AAC-LC, AAC-ELD, AAC-LD, HE-AAC formats, MPEG-L2 and L3, enhanced-aptX, G722, and G711.
The Opus algorithm handles both speech and music in a single multiple-bitrate algorithm that natively manages error concealment and adapts to varying issues, such as packet loss and variable bandwidth, encountered on difficult networks. High-quality speech can be encoded at bitrates as low as 24 to 32 kbps, and the low latency of Opus allows it to support audio contributions from reporters in the field. At higher bit rates, the music-encoding quality of Opus makes it comparable to AAC encoding.
Both the IQOYA *CALL and IQOYA *CALL/LE are now shipping with the free Opus software option.
