Overview

HF 3rd band equalizer is intended to process audio wave files exactly the same way as would do a real audio equalizer. Imput files can be 8 or 16 bits, mono or stereophonique. It uses a limited amont of memory and no swap file, so wave file length is only limited by free disk space. The best compromise time / quality reproduction is found for each equalizing curve. Real time listening is possible through windows audio mapper.


Distribution contents

This software shall has been released in 3 files :

hf3beq32.exe , file_id.diz , hfbequ.hlp


Installation

Distribution contents

Simply copy hf3beq32.exe and hf3beq.hlp in the installation directory. Then drag the .exe file from the file manager to the program manager. No dll is required. Uninstall happens the same way, removing both files.

Note: this 32 bit version works fine  on Windows NT, Windows 3.1 and 3.11 using win32s API. It should also work on Windows 95 (I havent tested yet).


How to use

The following bitmap represent the application window :

Move spin buttons until obtaining appropriated curve, then select file menu to open and save files. Application also supports drag and drop. Saving with same file name will overwrite *.wav file, since no temporary file is created, existing one will be immediately affected.

Process is done in background and can be stopped at any time with menu item control / stop. Real time monitoring is performed by clicking the control/play menu.

Some Tips


Tips

*	If hard disk is large enougth, it is more prudent to save result as a new name.

*	Result sounds best with 16 bits samples

*	The software algorithm does not check nor prevent saturation . If general level cursor is mistuned it can result in awfull sound wave (like with any digital audio rack).

*	Real time processing is time consuming and may not work correclty on slow PC and hight sampling rate.
