Devin Kerr » Free_Elastic: Independent Pitch/Speed Control in Max
This Max patch uses high-quality, FFT pitch shifting and is based on the standard groove~ object. It allows for much more control and customization (fft size, overlap, etc.) than “elastic~” does, and it’s FREE!
I have placed some AC3 surround recordings of Bundanon online for your enjoyment

You can play them using a multichannel interface and VLC player, and using headphones and the virtual surround function in VLC, they sound rather amazing and are very relaxing
elastic~ - the ultimate pitch-shifting time-stretching looping MaxMSP object
elastic~ works very much like the established groove~ object found in the standard MaxMSP library but with two totally independent controls: Pitch and Speed. The algorhythm used is designed specifically for musical material, allowing a natural sounding pitch shift up to an octave above and below the original pitch of your sample, whilst playing back at up to double or half speed. elastic~ is the easiest to use, highest quality, pitch-shifting / time stretching object available for MaxMSP.
AudioTouch « AudioTouch is an interactive multi-touch interface for computer music exploration and collaboration. The interface features audio based applications that make use of multiple users and simultaneous touch inputs on a single multi-touch screen. A natural user interface where users can interact through gestures and movements, while directly manipulating musical objects, is a key aspect of the design; the goal is to be able to interact with the technology (specifically music based) in a natural way. Users can load, exit, and move musical applications using gestures as well as have a multiple applications operate within the same work environment. The design is built into a table that hides all the hardware necessary for tracking multiple inputs as well as displaying visual feedback on the touch surface. It currently consists of 4 main apps:
MultiKey, the first application, is similar to a typical musical keyboard or piano. The application includes two polyphonic musical keyboards.
The second application, MusicalSquares, consists of color coded squares that bounce around within a bounding box. As the squares come in contact with each other, they collide, play a musical note (based on their color), and then bounce off each other in opposite directions.
Audioshape sequencer, is a third applications that allows users to create musical loops. Squares can be moved around and connected. When the play button is pressed on a square it plays through the connected squares in sequence.
Lastly, Musical Wong, is a multitouch game similar to pong/hockey. When the ball hits the walls, different sounds are played.
The Visual Virtual Microphone VST is a VST plug-in to derive virtual microphone signals from b-format Ambisonic recordings.Visual Virtual Microphone VST
VVMicVST calculates up to 8 virtual microphone signal from a b-format input.
The MicPortPro from CEntrance looks like a useful gadget for field recording projects - it is a professional USB mic preamp with true plug-and-play installation. It enables instant computer recording with Windows (XP and Vista) and Mac OSX and features 24-bit/96kHz performance, 48V phantom power, and loud headphone output.
I met Etienne Deleflie last week at the SoundCulture workshop at Bundanon. I thought his approach to streaming surround sound over the net was very interesting and well worth recommending to others.
Ambisonia.com is a web site that has been developed to
help the ambisonic community share and showcase their work,
help newcomers access ambisonics,
grow the ambisonics community by building a micro-economy around creating/publishing work.
You might want to read a more 'ground up' description of ambisonics and ambisonia.com.
Ambisonia.com has now become a publishing platform for any producer/amateur wishing to expose their surround sound work to the world. The long term aim is to create a mini-economy around the production and publication of surround sound work, hence enabling the community to continue their work.
Ambisonia was originally started by Etienne Deleflie in late 2005 as www.ambisonicbootlegs.net. The name was changed since there were, in fact, no bootlegs on the site
The Core Sound — TetraMic is the first portable, single point, stereo & surround sound Ambisonic soundfield microphone to be available for under $1000. Core Sound say it is the finest performing microphone of its type in the world.
Based on the principles of Ambisonic recording developed by Michael Gerzon and Peter Craven during the 1970's, TetraMic allows you to place a single exceedingly accurate tetrahedral microphone in a sound field, record four channels of audio in "A" format, transform them using software into "B" format (W, X, Y and Z), and later interpret those four channels to essentially any single-point configuration of microphones:
omni
sub-cardioid
cardioid
super-cardioid
hyper-cardioid
figure-8
multiple combinations of those including:
Blumlein (two crossed figure-8 microphones in the azimuth plane))
This little Honeytone Amplified Speaker made me want to take up busking - how cute is it? - 1-watt amplifier with 4-inch speaker. Only 5 inches square by about 2-1/2 inches deep and weighs only one pound. Uses 9-Volt battery
The Aquarian Audio :: H2a-XLR Hydrophone is designed to work with any PA system or recording device that offers a balanced, phantom-powered, microphone input. It uses the same low-noise, robust transducer assembly as our other hydrophones, but includes a low noise internal buffer preamp. Operation is very simple: just plug in and use. No additional power supply or proprietary preamp is required. The H2a-XLR offers the following advantages:
Relatively Low cost
Low self noise
Good sensitivity
High dynamic range
Works with any common phantom power voltage
Robust design handles accidental drops and temperature extremes
Compact (4.5mm OD) Low-noise cable with tough urethane jacket
Connects directly with pro condenser microphone circuits.
High-quality Neutrik gold output connector
Compact size and easy hand of cable
High specific gravity and streamlined shape keeps hydrophone down in currents
