Paul's Extreme Sound Stretch - 0 views

  •  
    "This is a program for stretching the audio. It is suitable only for extreme sound stretching of the audio (like 50x) and for applying special effects by "spectral smoothing" the sounds. It can transform any sound/music to a texture. The program is Open-Source and it's released under the version 2 of the General Public License. You can download the source code for Linux or the Windows binaries. Please note that this is suitable only for extreme time stretching (e.g. if have a melody of 3 minutes and you want to listen it in 3 hours). If you want "less extreme" time stretching, you can use a program which contains the SoundTouch library. Features It produces high quality extreme sound stretching. While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching. So, the stretch amount is unlimited. You can play the stretched sound in real-time (including the possibility to "freeze" the sound) or you can render the whole sound or a part of it to audio files It has many post-processing effects, like: filters, pitch/frequency shifters Support for WAV, OGG VORBIS files and MP3 files It is a Free Software "

Eleven Ways to Improve Online Classes - 0 views

  •  
    "It has me thinking about what it would mean to improve online classes. A few ideas come to mind: Use multiple platforms. I'm not against using an LMS as a central hub. However, I think it's valuable to experiment with the types of productivity tools you will actually use outside of a classroom. Use Google Docs to share ideas, create surveys, and ask questions. Use Google Hangouts to meet as a group. Go project-based. I haven't figured this out entirely with my first class but my hope is that we can go fully project-based in the same way that my face-to-face class is. In fact, the asynchronous nature of online classes actually means there is a better potential of creating a project-based culture that mirrors the way people actually work on projects. Make something together. I use a collaboration grid with co-creating and communicating on separate spectrums (x-axis) and multimedia and text on another spectrum (y-axis). This has been an effective way to think through collaborative tools that allow students to co-create. Embrace a synchronous/asynchronous blend: I love using Voxer because students can speak back and forth in the moment. However, if they miss it, they can listen to it later. The same is true of using a Google Hangouts On Air. Make it more connective. We tend to treat online instruction as if it is a linear process and we don't do enough to link things back and forth and connect ideas, resources, discussions and content creation in a seamless, back-and-forth nature. Incorporate multimedia. It's a simple idea, but I create a short video at the beginning of each week and I encourage students to create video and audio as well. This has a way of making things more concrete. There's something deeply human about hearing an actual human voice. I know, crazy, right? Go mobile. I don't simply mean use a smart phone. I mean assign some things that allow students to get out in the world and create videos, snap pictures,

Energy Return on Energy Invested (ERoEI) for photovoltaic solar systems in regions of m... - 0 views

  •  
    "Abstract Many people believe renewable energy sources to be capable of substituting fossil or nuclear energy. However there exist very few scientifically sound studies, which apply due diligence to substantiating this impression. In the present paper, the case of photovoltaic power sources in regions of moderate insolation is analysed critically by using the concept of Energy Return on Energy Invested (ERoEI, also called EROI). But the methodology for calculating the ERoEI differs greatly from author-to-author. The main differences between solar PV Systems are between the current ERoEI and what is called the extended ERoEI (ERoEI EXT). The current methodology recommended by the International Energy Agency is not strictly applicable for comparing photovoltaic (PV) power generation with other systems. The main reasons are due to the fact that on one hand, solar electricity is very material-intensive, labour-intensive and capital-intensive and on the other hand the solar radiation exhibits a rather low power density."

Conflict-Free And Easy To Repair, The Fairphone Is The World's Most Ethical Phone | Co.... - 0 views

  •  
    "The Fairphone is a modular handset designed with repairability and ethical sourcing of its materials as headline features. It sold 60,000 units. Amazingly, for what sounds like a nerd-phone, almost half of those buyers had never owned a smartphone before. Now the Fairphone 2 is launching, and with a totally-new, in-house design. The new phone is even easier to repair, and because it was wholly designed by the FairPhone team, its supply chain is even more responsible than ever. The Fairphone is thicker than the latest iPhone or Samsung flagship, but that's the point. Instead of packing everything into a tiny case and keeping it there with glue, the Fairphone is designed to be taken apart. The lightweight magnesium frame supports modules that can be easily replaced by the user. "We have designed it with an aim to last three to five years, looking at making it robust and modular-for repairability," says Fairphone's chief communications officer, Tessa Wernink. "Obviously how long it lasts depends quite heavily on the user, so what we as a company are doing is offering an ecosystem around the phone that supports long-lasting use, first-hand or second-hand." Inside the case (itself one of several options) you'll find the core unit, containing all the chips and radios; a replaceable battery pack; a display that can be snapped off and replaced without any tools (not even a screwdriver); a receiver unit, which contains the front camera, sensors; the headset connector and microphones; a speaker/vibrator unit; and a camera module. These modules are designed to balance manufacturing complexity with repairability. For instance, the display comes as a standalone unit, but less-vulnerable components are bundled into one module. The camera, which people are most likely to upgrade as better versions become available, is also housed in its own module. That way you don't need to toss out your whole phone just to get a better camera. "In fact, the motto from the maker mo

Sonido que habito. Innovación educativa: Un punto de 'no retorno' - 0 views

  •  
    "El proyecto consistía en la utilización de dispositivos tecnológicos móviles, de fácil acceso, en la grabación y geolocalización de sonidos del entorno próximo. La selección y tratamiento de los sonidos, les servía de desencadenante para el estudio de la propia naturaleza del sonido, la indagación geográfica, histórica, científica, ética, estética… de los conceptos, sensaciones, sentimientos y quehaceres presentes o sugeridos tras la escucha del sonido capturado -el 'sonido que habito'- y su posterior comunicación y divulgación en un blog colectivo."
