The Fraunhofer Institute for Integrated Circuits IIS and Thomson today announced the addition of two new elements to the MP3 Surround demo software: MP3 SX (MP3 Stereo eXtended) allows enhancing MP3 stereo files for multi-channel playback and Ensonido provides portable MP3 Surround sound using stereo headphones. Demo software of these two new enhancements to the MP3 Surround technology are now available and can be downloaded for free at www.all4mp3.com.
Supporting a seamless transition from stereo to surround sound, MP3 SX enables listening to two-channel content in surround and guarantees playback with a stable localization of vocalists and solo instruments even off the sweet spot. Additionally, MP3 SX presents the feeling of envelopment by using the ambience sounds already present in the stereo source.
Traditionally, surround sound has been primarily limited to loudspeaker setups in living rooms or theaters. With the Ensonido technology, the individual listening experience through portable MP3 Surround players and stereo headphones is enhanced. To achieve this, an acoustic model simulates the natural transmission of multi-channel sound from the loudspeakers to the human ear.

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
