IK Multimedia's $250 drum machine, Uno Drum, is available starting today. The company announced the portable, battery-powered device last month, but we weren't sure when it would be available.
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.
Digital audio. There's a very good chance that you've enjoyed some today. It's one of the more universal aspects of technology. In fact, perhaps the more relevant question would be, when was the last time you listened to an analog format? The truth, for many, will be quite some time ago -- vinyl purists and the odd cassette fanatic aside. Yet, despite its ubiquity, there's a lot of misunderstanding and confusion about digital audio. Some believe it'll never match analog for true fidelity, some assert quite the opposite. Many lament the lack of a tactile format, while others love the portability that comes with zeros and ones.
In this installment of Primed, we take a look at the history of digital sound, as well as provide an introduction to some of its key components, with the view to helping us understand it better. Wondering what bitrate to encode your MP3s at? Or whether you should choose a 96 or 44.1KHz sample rate? We thought as much. By the time we're through, these questions should no longer lay heavy on your mind, and you can enjoy that latest Knife Party, or Britney track as much as its bit depth allows. What's bit depth you say? Well, read on to find out...

Look out silicon and magnetic storage, here comes glass. Micron has announced production of the first commercial cellphone phase-change memory (PCM) modules, a type of flash RAM that works by changing a crystal solid to an amorphous state. The 1Gb chips will share a circuit board with 512Mb of standard volatile memory, just enough to go in feature phones for now -- but the company claims it will eventually offer larger modules for smartphone and tablet storage as well. PCM could scale to much faster speeds than conventional NAND flash, since it doesn't require a time-sapping erase before rewriting -- and with read speeds of 400MB/s, it's already into regular flash territory while still just a first generation product. Once the tech gets even quicker, PCM could even replace volatile RAM, allowing more secure storage in case of a power loss and reducing device costs and power usage. That means the glassy new kid could eventually bump silicon-based storage altogether -- ending its 40-year plus reign as king of the memory substrates. To see some of the ways it trumps NAND, check the video after the break.
