The Music Experiment Development System (MEDS) is a Windows based environment for developing and running multimedia perception experiments. MEDS has been under constant development since 1990. Grants under two occasions have been provided by the Intel corporation. |
| MEDS allows experimenters to test perceptual aspects of a myriad of multimedia stimuli. Direct support is provided for sampled sound, midi playback and keyboard responses, .AVI digital video and animation (with sound), laser disk, CD audio, bitmaps of scores or images, and numerous subject response mechanisms, including words, images, keypresses, and sound responses. | MEDS provides facilities for signal synthesis (single note and polyphonic), including re-synthesis, FFT-based analysis, and various data editing and statistical functions. All components of MEDS save data in ASCII format, and dynamic linking is provided directly to SPSS, SYSTAT, and Statistica. |
|
The MEDS environment is visual and (quasi) object-oriented. Objects representing stimulus and response conditions are placed on a time-line. MEDS provides high normalization of connections between objects for many psychological experiments; modification is easily accomplished through Visual Basic, the core language. |
| MEDS is in use in various laboratories world-wide. The program is provided via the internet for scholars, free of charge. Disk and CD-ROM versions, including hard copy documentation, are available for a fee. Distribution is not freeware or shareware, and is controlled by the Systematic laboratory. Source code can be obtained by application to Kendall@ucla.edu. |
Do not try to run MEDS without printing and reading the documentation.
ca. 4.5 MB
All previous versions of the program should be uninstalled before installing the new version.
The file is a .ZIP file that should be extracted to a folder on your hard drive. Then run the setup.exe program.

Trouble Reports - Email me: Kendall@ucla.edu
Please Note--
Video Users: MPEG and video playback CODECS (compressors/decompressors) are *not* installed by MEDS. These are commercial products installed for shareware in a number of applications. MEDS does not license them for distribution, although it supports playback once they are installed.
A source for a free Codec for MPEG2 files can be obtained by emailing me.
Contact kendall@ucla.edu for more information on MPEG video capabilities.
MEDS will NOT be updated to VB.NET, or any .NET product. I am searching for a grant to port MEDS to another language.
