Faber Acoustical Electroacoustics Toolbox

Faber Acoustical has released Electroacoustics Toolbox 3.0, a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac.

It brings powerful new tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. It enables precise measurements of acoustic quantities, such as equivalent and time-weighted sound levels, as well as acoustic and electroacoustic systems, such as listening rooms and loudspeakers. The software is designed to work with any Mac-compatible audio hardware and supports multiple channels of 8, 16, 24, or 32-bit data with sample rates as high as the hardware will support.

Changes in Electroacoustics Toolbox 3.0

  • Version 3 sports an improved user interface.
  • User preferences are available for individual tools.
  • Default audio device configurations, including channel labels, units, and sensitivity can be saved.
  • Virtual input channels can be added to audio input devices. Two-channel signal arithmetic (add, subtract, multiply) is now supported.
  • Arbitrary FFT lengths may be specified in FFT-based analysis tools.
  • Sound Level Meter and Octave Analyzer tools support percentile-exceeded sound levels.
  • Extended low-frequency support has been added to the Octave Analyzer.
  • The Spectrogram supports log frequency scales and real-time 3D spectrogram display.
  • Version 3 includes various other improvements over previous versions.
  • The Toolbox may now be purchased and maintained through the Mac App Store.

Electroacoustics Toolbox 3.0 for Mac is available to purchase for $599 USD.

Voxengo SPAN

Voxengo has announced the release of version 2.2 of SPAN, a real-time “fast Fourier transform” audio spectrum analyzer plug-in for Windows and Mac.

SPAN provides you with a very flexible “mode” system which you can use to setup your sound analysis preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum’s visual slope. Beside that you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum). Spectrum can be visually smoothed out for an easier examination.

Changes in SPAN v2.2

  • Correlation meter values around -1 are now displayed correctly in the “density” mode.
  • Statistics “reset” function now resets statistics of all channels correctly.
  • K-metering modes now use fixed 600ms RMS and release time constants.
  • Additional visual look variation settings added.
  • Underlay color selection was removed – group’s defined color is used now.
  • “Hide Meters and Stats” switch added.
  • Spectrum display is now more precise in high-frequency region.

SPAN is available to download as a freeware effect plug-in for Windows and Mac (VST/AU).

Expert Sleepers Spectral Conquest

Expert Sleepers has released version 1.0.1 of Spectral Conquest, an effect plug-in that lets you directly manipulate the frequency spectrum of audio signals.

The incoming signal is analysed via a FFT (Fast Fourier Transform), resulting in the familiar spectrum plot where the full audio spectrum is split into a number of narrow frequency bands. The outgoing audio is then regenerated by an Inverse FFT. The interesting bit is that the plug-in lets you modify the frequency spectrum in between.

Changes in Spectral Conquest v1.0.1

  • Improvements to the interactive painting of dense spectral data.
  • (VST versions) Fixed issues with slow GUI updates when running scripts or painting spectral data.

Spectral Conquest is available to purchase as an effect plug-in for Windows and Mac (VST/AU) for $29 USD. The plug-in is also available as part of the Ultimate Bundle for $155 USD, and the Creative Effects Bundle for $55 USD.

The outgoing audio is then regenerated by an Inverse FFT. The interesting bit is that the plug-in lets you modify the frequency spectrum in between.

Spectral Conquest allows you to modify the spectrum in two ways:

  • By setting a multiplier for each frequency band. You can simply draw out the multipliers in the GUI.
  • By applying a script to the spectrum. Some basic scripts are included with the plug-in to perform operations such as filtering and gating, but you can also write scripts yourself to do whatever you like.

Spectral Conquest is available to purchase as an effect plug-in for Windows and Mac (VST/AU) for $29 USD. The plug-in is also available as part of the Ultimate Bundle for $155 USD, and the Creative Effects Bundle for $55 USD.

A demo version can be downloaded from the Expert Sleepers website. It is fully functional, except that it will time-out after 15 minutes of use. Simply reloading the plug-in resets the time-out.

Short links for April 19th, 2010

Some interesting things I found recently:

# Bendable, Musical Shoes for Nike, and How They Were Made

Peter at Create Digital Music writes:

Shoes are the new turnables.

Or at least that’s the conclusion you might reach after watching a new Japanese campaign for Nike’s Free Run+ running shoes. Apparently wishing to tout the bendable qualities of its new footwear, Nike enlisted sound artists to transform its product into a musical instrument. The shoes get plugged in, switched on, and mixed up, battle-style, as they sense when the shoe is flexed or moved in space. And yes, everything you see in the video is real: the shoes really are controlling digital sound live. We even have the Max patch to prove it.

# What’s wrong with transient shapers?

Kim Lajoie writes:

Transient shapers are processors that adjust the dynamics of a sound. Rather than changing the dynamic range like a compressor, transient shapers operate only on the initial onset of the sound – the transient. The initial smack of a drum. The plink of a piano. The pick of a guitar or bass. They don’t work with sounds that don’t have a sudden start, such as vocals, violins, or synth pads. Transient shapers can either bring out the transient – making it louder, sharper and more prominent. They can also reduce the transient – making it softer and duller.

The tricky aspect to consider here is that the psychoacoustic (perceived) effects of a transient shaper can be similar to those of other tools.

# Xdrum, a sample based rhythm composer for Native Instruments Reaktor 5.

It has 800 audio samples (75MB) from 49 vintage rhythm composers, and then 11 additional soundsets. Besides that it has around 92 preset classic and electronica preset patterns.

Xdrum is available as a free download. via waka_x @ Twitter

# Fleischprodukt Waveshaper

A simple waveshaping plugin with various transfer functions (tanh, sin, atan, fold back, saturate, etc.) as AudioUnit Universal Binary for Mac OS X from 10.5 upwards.

Roland Dimension D

# Omega 8 into Roland SDD-320 Dimension D

Calvin writes:

Fired up the ol' Roland Dimension D today, because I was working on a track that needed something different. It's the Omega 8 that you're hearing here – more specifically – I've selected certain patches that I think work well with any sort of chorus. No particular order here in terms of the SDD-320's setting. I used every combination possible, going from each individual number all the way to 1+2, 1+3, etc. etc.

# FFT Algorithm Based Audio Spectrum Analyzer

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor.

NitroTracker

# NitroTracker, Fasttracker II style tracker for the Nintendo DS goes open source.

I’m very excited to announce that NitroTracker is now completely open source!

What does this mean? Well, for starters you can now have a look at the source code. More importantly, you can now help develop it! Together we can make the development of NitroTracker go faster (which would be a very good thing considering current development speed) and finally add long-awaited features I promised ages ago.

The source code is available from http://code.google.com/p/nitrotracker

# The Future of Multi-Touch: Behind the Scenes with Stantum, JazzMutant Co-Founder

Peter Kirn takes a look at the future of multi-touch:

For a long time, technologists have described a world of in which computing experiences naturally incorporate touch and gesture. The question is, how do we bridge the intuitive desire for those interactions and the actual technologies that get us there?

Few activities test the expressive potential of interaction quite like music. It’s in our cultural DNA; musical activity may even predate written language. So it’s fitting that the story of touch in computing and digital music would be intertwined, as they are with touch pioneer JazzMutant. Years before well-known Apple products, the Lemur, prototyped in 2003 and shown as a musical multi-touch screen, suggested the importance of fusing display and touch, and of tracking more than a finger or two at a time.

The history, and products like Apple’s iPad and iPhone, you may know well, though. The question on everyone’s mind now is, what’s next? (And for some impatient futurists, the question may even be, what’s taking so long?)
