ESDi requires very little resources, both in terms of memory and cpu.

Licence Key

If you have accidentally keyed the same licence key on two copies of ESDi, both will fail to run. You will need to delete data from the registry if you have already entered a key you wish to change. Click Start, then run, then type regedit and press enter. You will need to delete the registry key HKEY_CURRENT_USER\Software\ESDi\KEY


If you are using the same sound device for input & output, then it must be full duplex. ESDi uses 16 bit mono, running at 11025HZ sampling rate.

If you can get 'sound recorder' (which is supplied with the windows operating system) to work then so will ESDi.

The first time ESDi is ran, preferred audio devices are used. To set your preferred devices- Open 'my computer', 'control panel', then 'multimedia' or 'Sounds and Audio Devices' or 'Hardware and Sound' depending on the version of Windows you are using. For Vista and Windows 7 under 'Sound' select 'Manage audio devices'. Also here 'show volume control on task bar' can be set.

Audio settings for XP or earlier

Volume control - check your volume controls for playback and record. (See 'properties' in volume control menu for switching between record & playback settings). Check mute is off. Check any 'boost' is selected. (usually found under advanced - so advanced needs to be selected at the menu) Finally, check that a microphone is 'selected'.
