We see from your search that you're looking for information on the term "Microphone",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release IC boosts audio possibilities for mobile phones from
austriamicrosystems, which we summarised at the time by saying "An on-chip 512Kbyte buffer memory in the AS3532 music player IC allows single-chip support of all key audio formats, both compressed and lossless".
Earlier in the week,
we featured the news release Codec/power combo targets next-generation mobiles from
Wolfson Microelectronics: "Multimedia codec with integrated power management features delivers high performance audio and mixing capability, longer battery life and reduced system cost".
In January 2008, we covered the news from NXP Semiconductors
concerning its PNX6712
- take a look at Small baseband cuts multimedia costs
which says: "The PNX6712 forms the engine of NXP's Nexperia Cellular System Solution 6712 - a powerful HSDPA/HSUPA/EDGE platform, enabling sub-US $30 electronic bill-of-materials (eBoM)".
Take a look also at the news release from austriamicrosystems, Analogue companion cuts power for portable design,
as well as Active cancellation keeps headphones quiet from Wolfson Microelectronics,
and Audio analyser puts microphones to the test from Prism Sound.
