GenericSeqMon

Matlab project for automatically converting audio files to spike files using the Neuromorphic Auditory Sensor.

Note

This project has been tested in a x64 computer running Windows10.

Previous considerations

If I clone this repository in the following path:

D:\dgutierrezATC\myrepos\GenericSeqMon\

Then I will have a folde architecture like:

                             --dist
                                 |
                                 --...
                             --jars
                                 |
                                 --...
                      --startup.m
                      --mainSoundDB
                      --...

Configuration steps

Few previous configurations need to be done before running the code:

1. If jAER software has been launched, please close it.
2. In Matlab, write edit libraryPath.txt
3. At the end of the file, please add D:\dgutierrezATC\myrepos\GenericSeqMon\host\java\jars
4. Save the file, and close it.
5. Close Matlab and open it again.

⚠️WARNING!: If you copy the Java libraries to another folder (eg. C:\dgutierrezATC\Documents\MATLAB) then you would need to change the absolute path in the file startup.m since it uses the function pwd to obtain the current path of the Matlab file.

---

🔑 Sometimes, after running startup.m, the following warning message could appear:

WARNING!: no usbiojava in java.library.path: usbiojava libary not found; either you are not running Windows, the UsbIoJava.jar is not on the classpath, or the native DLL is not on java.library.path

In that case, follow this steps:

1. Go to the folder D:\dgutierrezATC\myrepos\GenericSeqMon\host\java\jars\win64.
2. Look for the file usbiojava.dll.file and change its name by removing .file (so the file should be usbiojava.dll).
3. Finally, modify again the libraryPath.txt by adding at the end of the file the path to the .dll file (D:\dgutierrezATC\myrepos\GenericSeqMon\host\java\jars\win64).
4. Save the file, and close it.
5. Close Matlab and open it again.

---

Then, in mainSoundDB.m file, change both the source and destination directories.

• source = D:\dgutierrezATC\myrepos\GenericSeqMon\Dataset\audio
• dest = D:\dgutierrezATC\myrepos\GenericSeqMon\Dataset\events

Main steps

1. Run startup.m
2. Run mainSoundDB.m
