Praat is a powerful (in fact professional level), free, multiplatform sound analysis program developed in the Netherlands for phonetics analysis. RavenLite is free, but less capable than other freely available sound analysis programs. These prices are not justified in view of the close approximation of competing software for free or much less, including Praat. Unfortunately Cornell has opted in favor of making money rather than spreading science: a standard academic license is $400 and a student one semester license is $50. The graphics is good but user interface is a bit compex. It includes autocorrelations analysis, sonograms, power spectra, etc. RavenPro is a full featured sound capture and analysis program originally developed for bird calls and songs, by the Cornell Laboratory of Ornithology. Try your own search for it the developer is Christoph Lauer. It seems to be losing its presence on the web, unfortunately. Sonogram Visible Speech has useful features such as autocorrelation, and nice graphics. It records and plays back sounds, does a spectral analysis of recorded sounds, processes sound clips with dozens of tools, generates standard tones, computes the sonogram with adjustable parameters, and much more. Multi-platformĪudacity is available free for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems. WaveSurfer is a free and capable waveform-sonogram analyzer the graphics is quite good but the program lacks some of the sound generation and transformation tools available in Amadeus Pro for example. The general purpose ElectroAcoustics Toolbox includes an FFT and impulse response analysis, plus much more signal analysis and signal generation, but is sold as a professional tool at $499. Not cheap for such a limited purpose product at $29.95, it is very capable at what it does, that includes predetermined ramping of the frequency of two tones. SignalSuite makes signal generation much easier, suitable for driving experiments incuding studies of phantom tones (Chapter 25). The fully functional program may be freely downloaded with a 30 day trial period. It also costs $59.95 there is a 25% discount available for students. ![]() The author finds Amadeus Pro very useful, though it lacks autocorrelation computation. If you happen to own and use Mathematica, you can download the source code instead. In other words, the Shepard tones are not an illusion, but rather a direct consequence of a central property of our perception of pitch. The pitch rises from one note to the next but after 12 notes it is back where it started! I put illusion in quotes because the pitch really does rise according to our internal algorithms, showing that pitch is a qualitative impression like taste, not a quantitative measure of frequency. Some of these should not be missed, such as Pythagorean, Meantone, and Equal Temperament Musical Scales,Īnd Shepard Tones,, a surprising pitch "illusion". Of these, perhaps 5 or 10 are of high value to us, although that can change as more are being added every day. The multiplatform Player can be downloaded at, and then housands of pre-made demonstrations are easily run. However Wolfram provides a free CDF Player, that allows interactive exploration of thousands of programs others have written on the full version of Mathematica. It is extremely powerful, expensive, and flexible, with a steep learning curve and an unforgiving syntax. Mathematica is the signature product of Wolfram, Inc. Furthermore, Amadeus Pro's powerful denoising functions allow you to easily get rid of that annoying hiss on your old tape recordings or of that 50Hz hum picked up by a badly insulated microphone.Home | MAX patches | Software | Using Falstad applets | Recording Audio| Links Software Wolfram CDF Player The handy repair centre allows you to find and to repair cracks with a simple click of the mouse. Several hours of work in perspective? Let Amadeus Pro do the work for you! The powerful batch processor allows you not only to convert large numbers of files between any of the supported formats, but you can also instruct Amadeus Pro to apply any sequence of sound effects. There's that whole collection of files that you wanted to convert to Mp3, but you first wanted to normalize them and make them fade in and out nicely. Amadeus Pro fully supports multitrack WAVE files and allows you to render sound on up to 5 different loudspeakers simultaneously. ![]() ![]() Each track can have its volume adjusted independently from the others. Amadeus Pro is a powerful multitrack audio editor supporting a variety of formats including MP3, AAC, Ogg Vorbis, Apple Lossless, AIFF, Wave and many others.Īmadeus Pro is a fully featured multitrack editor.
