The EnAnalyse program has been written to perform standard statistical and spectral analyses of electrochemical noise time records. It is written in Delphi V5.0, and requires Windows 95/98, Me, NT or 2000 to operate. The current release (V1.2) has not been fully tested, although it is generally believed to be working essentially correctly. Known problems include the poor axis labelling of the log-log power spectra (this appears to be a limitation of the Delphi TChart component that I cannot easily change). I believe there is also an error of a factor of two in the PSD calculation (I don't currently have a working Delphi system, so I can't easily correct this).
The program will handle up to 1 M points in the time record, although this will require a large amount of memory for rapid processing. The display of the graphs requires even more memory than the calculations, so this is disabled for time records of more than 64 K points (although the graphs can be re-enabled after loading the time record). The program will currently only process a single time record, and if you want to compare current and potential spectra, you will need to save the spectra and re-plot with another program.
There is a known 'feature' that prevents it from reading comma delimited numbers. The program uses the Pascal read procedure, and this requires that sequential numbers are separated by spaces and gives an error if commas are used. The recommended solution to this is to use a text editor to convert commas to spaces. Where it is required to process many files, the BatchEnAnalyse program uses a modified input routine, and may be more suitable.
This program is offered to interested users with absolutely no warranty of any kind. It must not be used in life critical applications or for any application where financial or other losses may be incurred as a result of the operation (correct or otherwise) of the program, or for anything where wrong operation of the program may cause anything more than mild irritation.

This beta test release is freely available to all users, except that it may not be included in any package, collection or product that is sold for more than a reasonable cost of copying. Any such redistribution must specifically include this licence information.
If you accept the above terms, you can download the program. This will give the file EnAnalyse.exe. This file should be executed (double click in Windows Explorer, or use the Run command from the Start button), when it will extract the setup files to your Windows temporary directory and run the setup program.
Currently the program does not have any help system. The operation should be reasonably obvious, but please feel free to contact the author (preferably by e-mail) if you have any questions.
The BatchEnAnalyse program has been written to perform standard statistical and spectral analyses of electrochemical noise time records. It is written in Delphi V5.0, and requires Windows 95/98, NT or 2000 to operate.
The current release (V1.0) has not been tested very thoroughly, although it uses the same analysis routines as ENAnalyse, and it is generally believed to be working essentially correctly, except for the error in the PSD calculation as noted for EnAnalyse.
The program uses a different input routine from ENAnalyse, in order to overcome the limitations introduced by the use of the Pascal number input routines. The method used is rather crude (basically any string of characters containing only '0' to '1', '+', '-', 'E' or 'e' is treated as a number, and anything else is treated as a separator and ignored), and it may not be suitable for all input data formats.
The program will analyse as many sequential time records as it can from the data available. FFT and MEM spectra will be written to output files ending in a number that counts up from 0000 (the number of time records is consequently limited to 9999, although this is not tested for). Statistical results are output as one line for each time record in a single file. All files have a header line that identifies the contents of each column, and these should be readable as delimited data into Excel and similar programs (use ',' as the delimiter and '"' as the text delimiter).
