How to Prevent Windows 7 Sleep State While Using Spotify

I have been looking for something like this myself, the closest thing I found is SRS Audio Sandbox. It installs as a virtual audio device and modifies the sound output of every program. Unfortunately it is not a graphic equalizer but an "audio enhancer" that can be adjusted by parameters like "space level" "center level" etc, but maybe it can help you.

Edit: Have a look at VSTHost, and how you can use the virtual audio cable to route audio output through it as described here. I will definitely try it.

Open the Registry Editor, navigate to HKCR (although HKCU\Software\Classes would be a better location, but most are lazy). For every file type, create a zero-length string value named AlwaysShowExt.

For example, if you have .txt:

1. Navigate to the subkey for the extension – HKCR\.txt – and note the data stored in the "(Default)" value – it usually says txtfile.

2. Navigate to the file type subkey HKCR\txtfile, right-click the value list, choose New → String value, and name the new value AlwaysShowExt.

Not all extensions have separate subkeys for file types – sometimes all information is kept directly under HKCR\.myext. In such cases, AlwaysShowExt goes directly to the extension subkey as well.

It is very likely that there are dedicated programs for editing file types, possibly with support for AlwaysShowExt and other flags. I don't know any to recommend, though.
