morpheus83 writes "Akustica today introduced the first High Definition Microphone that enables HD voice quality in laptop PCs and other broadband mobile devices. The AKU2103 is a digital-output microphone with a guaranteed wideband frequency response. It is the first digital microphone to guarantee compliance with the TIA-920 audio performance requirement for wideband transmission in applications such as Voiceover-Internet Protocol (VoIP)."

    What is this supposed to mean?

    > that enables HD voice quality in laptop PCs and other broadband mobile devices.

    Meaningless, I use mics from cheap Chinese dynamics to rare vintage U47's. The acoustic environment and relative position of mic to sound source has more effect on the sound than the design.

    > a digital-output microphone

    It may have a digital output but it is not a digital output microphone! No more than there is any such a thing as digital headphones.

    The term High Def should not be applied to audio.
    It does mean something, but it doesn't seem to mean much. Instead of the 3kHz-ish bandwidth of your normal voice phone link, this standard provides 150Hz to 6.8kHz audio bandwidth.

    That, of course, is very well within the abilities of all kinds of crappy five-dollar microphones. This gadget is an integrated device with mic module, A/D converter and other jazz, but there doesn't seem to be anything else special about it.

    There's nothing stopping software VOIP systems from providing DC-to-daylight audio bandwidth if you've got the link bandwidth to support it. I would be very surprised if you couldn't get a zero-dollar VOIP connection today that sounds better than this new "improved" standard, if you use even half-decent mics at either end.

    Anyone got any more?

    At any rate it doesn't even say what type of microphone it is (condenser, dynamic?) and what's all that rubbish about being the first to have "L/R-user select function", because using 2 microphones to capture left and right separately has obviously /never/ been done before

    Who posted this? Honestly!
