STMicroelectronics along with the audio company USound has created the first MEMS (Micro ElectroMechnical Systems) micro-loudspeaker based on semiconductors. It’s the smallest loudspeaker in the world, but it can produce a powerful noise. MEMS makes it possible. The speakers are...

Small, versatile, fun, and inexpensive! Use the 254 word library to bring speech to your Arduino projects! Speak, Arduino, Speak! About a year ago, I designed an Arduino shield that allowed for you to add voice to your electronic designs.  I've since been able to minimise that design...

  XMOS is one of the many companies that has ventured in voice recognition technology. They created the VocalFusion XVF3500 device, the first voice processor to have true stereo-AEC support in a far-field linear microphone array solution. Voice recognition is a relatively new...

This project is the ideal solution for high output, high performance high fidelity stereo head phone amplifier. The project consists of Op-Amp LME498720 and LME49600 as output driver. The LME49600 is able to drive 32Ω headphones to a dissipation of greater than 500mW at 0.00003% THD+N...

Karlwoodward @ www.rs-online.com/designspark is in the process of designing a “guitar pedal” for amplification and distortion using the Korg Nutube we featured earlier. The Part 1 of a series of articles goes through the basic aspects of tubes and valves, the pros and cons on using...

An echo-canceling, far-field, linear array microphone for speech recognition and voice communications. Acusis is a simple-to-use, complete solution for improving the audio quality for your speech recognition or video communications project. It solves multiple audio issues in a single...

A new vacuum tube which puts vacuum fluorescent display technology to practical use is in distribution from RS Components. Nutube, similar to a conventional vacuum tube, has an anode grid filament structure, and operates exactly as a triode vacuum tube. Also similar to a vacuum tube,...

Sony has recently launched one of its new products, Spritzer! Spritzer is an Arduino-compatible board for IoT applications that has built-in GPS, audio codec, and low power consumption. While it is Arduino-compatible, the board allows any developer to easily start app development using...
