Image to Sound Mapping [Part 1] « The vOICe Home Page Page contents: Principles and frequency distributions The above figure illustrates the principles of the conversion procedure for the simple example of an 8 × 8, 3 grey-tone image (instead of the 64 × 64, 16 grey-tone mapping that we use in reality). The mapping translates, for each pixel, vertical position into frequency, horizontal position into time-after-click, and brightness into oscillation amplitude.
Many other types of frequency distribution could be used for an auditory display. The following template allows you to obtain lists of frequencies and frequency steps for several types of frequency distribution, and you can override several of the default parameter settings: Artificial scenes with FREE SOFTWARE The following figure illustrates the principles of the mapping for an artificial scene containing a bright diagonal line, three very short horizontal lines and a (partially) bright filled rectangle on a dark background.

Have you ever considered using Sum & Difference monitoring techniques to enable you to reverse engineer some of your favourite records? We all know that developing our listening skill is crucial as engineers and producers who care about the quality of our craft. Utilising some commonly found features on mixing consoles and monitor controllers, today’s blog entry outlines some interesting ways to help expose elements in perspectives you may not have heard very often. Mid / Side Basics So I am sure many of you have used mid/side techniques to record stereo signals, a technique that allows us to capture separate mid (cardioid most often) and side (figure-8) signals that can facilitate control over stereo content post-capture.
In a mid/side array, the individual microphone feeds are combined in a simple matrix in order to produce and vary stereo content. Check out this useful blog post from our friends Universal Audio that explains recording in mid-side. Reversing the Matrix Listening in M/S Enjoy! Home Page.
Izotope RX2 Tutorials for Post Production. Mixing. Tele-Present Water by David Bowen visualizes intensity and movement of the water in a remote location #maxmsp #arduino. Created by David Bowen, Tele-Present Water installation draws information from the intensity and movement of the water in a remote location.
Wave data is collected in real-time from National Oceanic and Atmospheric Administration (NOAA) data buoy station 46075 Shumagin Islands Alaska. The wave intensity and frequency is scaled and transferred to the mechanical grid structure resulting in a simulation of the physical effects caused by the movement of water from this distant location. The installation uses MAX/MSP to drive an Arduino mega running servo firmata. It uses 11 x 24volt dc motors with drivers for the movement.
In May this year Tele-Present Water received one of three ex aequo awards in Alternative Now: The 14th Media Art Biennale WRO 2011, Wroclaw, Poland. //thanks for the tip Joost 11 x 24volt dc motors Photo by Alicja Kołodziejczyk - source Photo by Ewa Wójtowicz - source. HTG Explains: What Are the Differences Between All Those Audio Formats? Digital audio has been around a very long time so there’s bound to be a plethora of audio formats out there.
Here are some of the more common ones, what differentiates them, and what to use them for. Before we talk about everyday audio formats, it’s important you understand the basics, and that means understanding PCM. After that, we’ll tackle compressed formats. PCM Audio: Where It All Starts Pulse-Code Modulation was created back in 1937 and is the closest approximation of analog audio. That is, an analog waveform is approximated in regular intervals. PCM is characterized by two properties: sample rate and bit depth. True sound, in the real world, is continuous. Image from Wikipedia I know there’s a lot here that may not be second-nature unless you’re an engineer, physicist, or an audiophile, so let’s pare it down further with an analogy. Let’s say that the water flowing from an open faucet is your “analog” audio source.
Bit depth is a little trickier. The Uncompressed Bunch: WAV, AIFF. Designing Sound. Smartelectronix.com :: free and donationware music plugins. Build an Infrasonic Subwoofer. EQ Chart | ObiAudio. This is from a thread on Future Producers..I did not write this and do…to an extent…agree with most of this. I just copied and pasted the good stuff: To understand EQ and its intricacies you need hands-on experience, but to help you get started, here’s a table of general uses and the different ranges that EQ can affect.
As every sound is different, though, these are necessarily very general guidelines… Kick Drum Any apparent muddiness can be rolled off around 300Hz. Try a small boost around 5-7kHz to add some high end. 50-100Hz ~ Adds bottom to the sound 100-250Hz ~ Adds roundness 250-800Hz ~ Muddiness Area 5-8kHz ~ Adds high end presence 8-12kHz ~ Adds Hiss Snare Try a small boost around 60-120Hz if the sound is a little too wimpy. 100-250Hz ~ Fills out the sound 6-8kHz ~ Adds presence Hi hats or cymbals Any apparent muddiness can be rolled off around 300Hz. 250-800Hz ~ Muddiness area 1-6kHz ~ Adds presence 6-8kHz ~ Adds clarity 8-12kHz ~ Adds brightness Bass Vocals Piano Electric guitars Strings.

Each alive cell has 4 states: Up, right, down, left. at each cycle, the cells move themselves in the direction of their internal states. This set of rules produces chaotic results in some settings, therefore you can end up with never repeating, gradually evolving sequences.

©1995 The Regents of the University of California by Regan Lum Introduction: A speaker is a device that converts an electronic signal into sound. The speaker you will build (see figure 1) consists of a Styrofoam or paper cup, a coil of wire, a permanent magnet, and a signal source. Figure 1 Purpose: In this laboratory, you will explore how a speaker works. Materials: 1 permanent magnet 2 feet of wire 1 pencil tape or glue 1 Styrofoam or paper cup 1 signal source (tape player) 1 plug with alligator clips for tape player Procedure: Assemble material as shown in figure 1.
Leaving about 10 centimeters on the end, wrap the wire around a pencil to make a wire coil and tape or glue it to the bottom of the cup. Conclusion Does the volume control on the tape player work on your speaker? Return to CEA Science Education Home Page. - Understanding DC-Offset.

Music evolution: Is this the end of the composer? 18 June 2012Last updated at 20:47 ET By Rebecca Morelle Science reporter, BBC News Professor Armand Leroi from Imperial College London explains why he thinks a Darwinian computer program that can evolve music from noise could kill off the composer You might think that creating the perfect piece of music - whether it's a classical great, jazz masterpiece or pop hit - is all down to the composer's talent, flair or even genius. Not so, according to Armand Leroi from Imperial College London. "What we are trying to find out is whether you need a composer to make music," says the professor of evolutionary developmental biology.
"And we don't think you do. " He believes a much more fundamental force of nature is at work. "We don't often think of music as evolving, but everybody knows it has a history and it has traditions. Scientists think that creating good music may not be the sole preserve of composers such as Mozart To begin with, the computer program randomly churned out two short loops of noise.
