ECos/Win: Experiment Generator and Controller for Windows
ECoS/Win is a unique way to quickly set up and run listening tests on PCs, without
the need for programming (or to pay programmers). The system is designed to work
on all multi-media PCs running Microsoft Windows 98/95/NT/3.1x.
Using our form-based interface, you can quickly specify the audio files to be
used and define the set of possible responses. ECoS/Win will then execute the
test on your command, faithfully sequencing and timing your test, displaying the
possible response alternatives on screen, recording each of the listener's responses
automatically and saving these to disk. The stimulus sets, block definitions,
etc., can be imported and quickly edited to define subsequent listening experiments.

ECoS/Win
uses a series of on-screen forms to specify the design details for your
experiment. The first of these screens is used to specify the type of
experiment to be generated with several global parameters of the experiment.
Once these characteristics have been specified, you can then move on to
define stimulus, response and timing details for each of the blocks of
trials in your experiment. |

Avaaz' Experiment Control System for Windows PCs (ECoS/Win) consists of two programs
that are used in sequence. The first program, EGen, lets you define the type of
test you want to conduct and specify the details of the test. The second program,
ECoS, lets you carry out the test and collect and score your data.
The audio signals used in ECoS/Win experiments may be natural speech that has
been sampled and edited (for example, using TFR), synthetic speech (for example,
generated using the Klatt Synthesizer in Avaaz' CSRE program), or any other acoustic
signals. These audio signals can be in either .wav (Windows) format or in .adf
(audio data file) format. Note that Avaaz' ADF2WAV utililty can be used for bulk
conversion between .adf and .wav files, if desired.
Signals are presented in a specified sequence, according to a timeline which you
define. All of the listener's responses are recorded automatically by the computer,
and logged to a disk file for scoring and subsequent analysis. Several types of
experiments are available (see below).
Key Features & Benefits
- Supports many common types of listening experiments - identification or discrimination
(comparison).
- Easy setup: simply fill in a series of forms.
You specify audio signals, response screens to be displayed, type of feedback
(if desired), and number of test trials.
- Tests run with timing and sequencing
as specified.
- Responses automatically scored as correct or incorrect and results saved to disk.
- No more programming.
Minimum Computer System Requirements
IBM compatible PC (Pentium or equivalent processor, with 16 Mb RAM and at least
16 Mb disk space), Windows 98, NT, 95 or 3.1x, with CD-ROM, SVGA monitor, Microsoft
Windows compatible mouse, and suitable audio hardware.
Audio Hardware
ECoS works with any Windows-compliant multimedia sound card (e.g., Creative Laboratories
Sound Blaster 16 or equivalent), as well as with the Tucker-Davis Technologies
System II hardware (www.TDT.com). Note: the
TDT hardware is required for adaptive intensity experiments.
