UFO Scientific has updated MultiFreek to version 2.4.

What's new:

• Frequency range selection added: see your spectrum on whichever detail you want.
• Global gain: increases/decreases overall spectrum amplitude magnification.
• Local gain: adjusts the magnification for each of the sources individually.
• Frequency inspector: precisely shows the frequency which your mouse cursor is over.
• Improved graph smoothing: new approach for graph smoothing which adds more readability even for very rich spectrum pictures and carefully real signal dynamics.

A short video guide is now available here.
