Digital microphone pioneer Akustica said it has gained a design win in Texas Instruments’ latest stereo audio codec chips, reports EE Times.
TI claims to be the first to add a digital microphone input to its codecs used in cellphones and other consumer audio devices. TI’s TLV320 enables Akustica’s digital microphone to bypass the usual analog-to-digital converter.
Akustica’s tiny digital microphone can now directly connect to TI’s codecs.
Digital microphones may deliver better quality by using the entire 20 Hz-to-20 KHz audio spectrum. Analog mics use only 5 KHz. “When you use a digital microphone, or better an array of them, it just sounds remarkably better compared to what we are used to hearing over the telephone,” said Ken Gabriel, co-founder of Pittsburgh-based Akustica.
Arrays of digital microphones can also enable sophisticated noise cancelling as well as beam forming that can track a users’ voice as their head moves relative to the microphone. TabletKiosk’s family of Sahara Slate PCs are shipping with an embedded “dual array” of its AKU2001 digital microphones.
