Position and Velocity Data

• Microbeam data for speaker JW16, located in the mbeam/subj1 subdirectory of the labc account.
• Microbeam data for speaker JW18, located in the mbeam/subj2 subdirectory of the labc account.

If you do not have access to the labc account, you can download the data from the Lab Database page.

The Tools

• MATLAB®, Mathworks®, Inc. (UNIX®/Linux®/Windows®)
   
• Microbeam display program, Mavis - MATLAB® scripts that are located in the MATLAB® subdirectory of the labc account.
   

If you do not have access to the labc account, you can download the Mavis scripts from the Lab Software page.
