Here ’s a mike described by Akustica as the first HD digital output mic , a tiny twist destined to be designed into laptops and broadband fluid devices . The company says this AKU2103 mic is the first to “ warrant compliance with the TIA-920 audio performance requirement for broadband transmission in applications such as Voice over Internet Protocol ( VoIP ) . ”
It ’s also immune to radio frequence ( RF ) and electromagnetic ( EM ) incumbrance , have laptop or cellular phone designers locate it just about anywhere on the machine , even if it ’s near a Wi - Fi antenna or LCD screen . But what on the dot is mean by “ HD audio wideband , ” anyway ?
Do n’t get too excited yet , because we just note that theTIA-920 definitionof “ HD sound recording wideband ” is a frequency reply between 150Hz to 6800Hz . Jeez , that ’s not precisely gamey - faithfulness . And how regretful does that make microphones that do n’t adhere to this guaranteed criterion ?
It ’s a real find , though . It ’s a CMOS mike , a tiny desegregate circuit , that output a digital audio signal . Cool . Do n’t bear to see this little button - size microphone in recording studio apartment anytime soon , but it might make a significant difference inside of a laptop computer or cellphone .
