Which ITU standard is associated with wideband audio for high-quality videoconferencing?

Wideband audio in videoconferencing means expanding the voice frequency range beyond traditional telephone limits to about 7 kHz, which makes speech sound more natural and clearer. The ITU-T standard that defines wideband audio codecs for this purpose is G.722. By providing this wider bandwidth, it improves intelligibility and overall sound quality compared to narrowband codecs. For contrast, G.711 is a traditional narrowband codec used in standard telephony with only up to about 3.4 kHz of audio range. H.239 concerns content sharing and a second video/data channel in videoconferencing, not audio encoding. GIF is an image format, not an audio standard.
