Wideband Audio

Audio transmission that captures a broader range of frequencies (typically 50-7000 Hz or higher) compared to narrowband telephony (300-3400 Hz), resulting in clearer and more natural-sounding speech. In accessibility contexts, wideband audio is particularly important for hearing aid and cochlear implant users, as the additional frequencies between 3300 and 8000 Hz have been shown to significantly improve speech recognition and decrease the mental effort required for listening. Meeting organizers can support wideband audio by encouraging participants to use computer audio rather than dialling in by phone, which is typically limited to narrowband.
