ESPS is a comprehensive set of speech analysis/processing tools for the UNIX environment. The package includes UNIX commands, and a comprehensive C library (which can be accessed from other languages). Waves is a graphical front-end for speech processing. Speech waveforms, spectrograms, pitch traces etc can be displayed, edited and processed in X windows.

The OGI Speech Tools, a set of speech data manipulation tools developed by CSLU, are available via anonymous ftp. The tools can be used to compute and display signal representations, label speech at different levels (e.g., phonetic, phonemic and word), train neural network classifiers, and display the output of classification or recognition algorithms time-aligned with the speech.

Signalyze 3.0 is an interactive program for the analysis of speech and other acoustic material. It contains a large set of signal editing, signal analysis and signal manipulation tools.

Signalyze 3.0 runs (only) on Macintosh computers. Signalyze 3.0 runs on almost all versions of the Macintosh. With a Macintosh AV or a Power Macintosh, you have all you need to record, analyze and reproduce professional 16-bit sound.

The SoundScope product family is used primarily in speech teaching & research, with some applications in animal sounds, forensics, and general acoustic analysis. It can record, view, analyze, play, copy, paste, store and print sound waveforms. Analysis functions include spectrogram, fundamental frequency (Fo), Linear Predictive Coding (LPC) including formant tracking, LPC residual, jitter (pitch perturbation), shimmer (amplitude perturbation), HNR, frequency spectrum, spectral slice, envelope, energy and zero crossing. Includes limited built-in filtering, runs any filter created with WLFDAP. An integrated text editor stores notes and calculation results. SoundScope lets you design your own custom "instrument" screen, tasks (macros) and menus. Supplied instruments include 1 channel analyser (dual snap, dual time, spectrogram, spectrum), 2 channel analyser, segment analyser, multi-channel recorder, etc. Note: Supercedes MacSpeech Lab II.

This FREEWARE package allows the user to view the time-wave and frequency spectrum LIVE from any Macintoshù sound input device. Real-time display is possible on faster Macintoshes; display rates of >110 frames per second are possible on a Power Mac 8100/100; >35 fps on a Quadra 950. A "Waterfall", or raster plot of previous spectral history, is presented in a separate window. Recording and playback of monophonic 8-bit sound is supported; a spectrogram can be made of the captured data; whether recorded by SoundView, or imported from any sound file. A readout provides the frequency value of a point specified by the mouse cursor.

 Sound Waves is an educational software which has the following activities:

 1. Explore Wave Forms
 2. Explore Fourier Decomposition
 3. Explore Human Hearing
 4. Demonstrate Interference and Beats
 5. Investigate Doppler Effect
 6. Listen for Resonances
 7. Solve Problems
 8. Have Fun with Sounds
 9. Get References and Resources
   

To whom was the software intended and who uses it?

 Sound Waves was developed to help introductory physics students learn
 about the physics of sound.  It has been used by physics instructors
 to demonstrate the interference of sound waves and the generation of
 beats.  Several applied mathematics instructors have used it to
 demonstrate Fourier decomposition.  It has been used along with
 earphones in laboratory settings at the high school level in the USA,
 and by many students who enjoyed the challenge of a game-like
 approach for solving simple problems about the Doppler effect and the
 relationship between the sound speed, the frequency of the source and
 the wavelength in the medium.  Recently, instructors of
 multi-disciplinary science courses have used the references section
 to discuss acoustic inspection as an agricultural tool, sound driven
 refrigerators, and taking the ocean's temperature with sounds.
 Younger children have enjoyed the "have fun with sounds"
 activity and their teachers have used the software to increase their
 interest in science.

A nice sound editing shareware program for windows.

Another nice sound editing shareware program for windows

Gram produces a high resolution color map of the frequency structure of any digital (PCM) audio file. If you also have a Windows compatible sound card, you can record and directly analyze sounds through an attached microphone as well as play back the recorded audio spectrum showing the variation of frequency structure with time. Use Spectrogram to reveal the hidden complex frequency structure of sound samples, to compare and identify different sounds, or identify the formants of human speech

4.2.5 for windows 95

Gram23    Program to display "wav" files as a sonagram under Windows 3.x

• http://bul.eecs.umich.edu/signal

  This program samples the input from a sound card, performs an FFT, and graphs the output. INI file, command line, a nd run time options provide the user with the ability to select linear/log frequency and amplitude scales as well as sampling rates, length of the FFT, and windowing functions. Graphics is done using the VGA 640x480x16 video mode, so a VGA compatible card is required.

  Three versions of the program are included. The first will run on 386+ computers, under DOS, using 8-bit Soundblaster (or compatible) cards, 16-bit Soundblaster cards, ProAudio Spectrum-16 cards, or any card which supports the VESA audio interface BIOS extensions (such as the MediaVision 3D series).

The current version can be downloaded from author's home page under the title: Audio Signal Processing Programs

You can download the demo from AVAAZ's homepage.

From the Web Site:

"TFR uses an intuitive and readily-learned graphical user interface with full mouse control and on-line help, to provide a full range of signal processing functions on PCs. It is Windows-based, and works with any Windows-compatible 16-bit audio card. The program offers the most complete range of signal analysis technques available in any package. Results are displayed as high-resolution spectrograms, in color or in true gray-scale. In addition, our display utilitites are "open" so that users who have their own, even-more-specialized analytical techniques can still use TFR to display the results of their analyses."

UNCERT analyzes sequential data by the method of Markov chains, providing first-and second-order transitional matrices with associated uncertainty (entropy) values. The user creates and names a data file according to instructions in an ascii file called README. (The README file must not be renamed because it can also be called within a run of UNCERT itself.) Then the interactive program is run with the user providing simple responses to prompts. A summary of results is provided on-screen, and the full results are written to a new file _x that is named by the user. This results file includes:

(a) the name of the file containing the data analyzed;

(b) the parameters of the data set;

(c) a summary table of samples on which different orders of Markov chain were based;

(d) maximum uncertainty;

(e) zero-order analysis,

(f) first-order analysis, including tables of transitional frequencies and probabilities;

(g) second-order analysis, including tables of transitional frequencies and probabilities;

(h) uncertainty summary;

(i) if specified by the user, tables of transitional frequencies and probabilities of naturally defined units in the data; and

(j) an analysis of the feasibility of running higher orders of analysis than can be done by UNCERT.

Background, including the techniques of Markov chains and comments on analysis of behavioral data using UNCERT, is provided in an accompanying ascii-formatted manual.

EthoLog is a tool for the transcription of behavior observation sessions. The behavioral categories and their key codes are defined by the user in a text file. EthoLog is designed to deal with two kinds of events: State Events, which have durations, and Instant Events, which have times of occurrence (and are embedded in State Events). State Events are distinguished from Instant Events by a Space Bar press before the key code (so any category can be used as a State or Instant Event).The user can add Labels to any registered event, which can act as notes or modifiers. The transcription sessions can be paused and resumed. EthoLog generates two text files with a session summary and the full sequential and timing data. These files can be loaded to a spreadsheet for further analyses.

Special requirements: none.

software for Exploratory Sequential Data Analysis (ESDA).

...from the Web page:

MacSHAPA is one of a number of software tools now emerging to help with the problems of ESDA (for other examples see Sanderson, 1994). MacSHAPA does not help with every kind of ESDA--no software tool can--but it does help with certain kinds. MacSHAPA lets you do the following: Enter or import data into a spreadsheet-like viewing medium Annotate, manipulate, and visualize data in various ways Carry out statistical analyses of various kinds Export data and results to other applications. Full information about MacSHAPA's features and use can be found in Sanderson, Scott, Johnston, Mainzer, Watanabe, and James (1994).
