LineSpec

LineSpec is a lightweight library designed to help developers extract spectrum data from a recording device. With its help, one can grab the spectrum information without effort.

LineSpec handles the recording process either in the same or a separate thread, delivering 1 to 1024 spectrum values per channel. Optionally, it can be configured to extract spectrum data associated with a specific channel, either the left, the right, both or mixed.

Thanks to the list of pre-calculated values it uses, the library delivers high processing speed. All its demo applications are configured to run in the background, so as to not interfere with your work or clutter the system. However, you can use keyboard shortcuts to interact with LineSpec. Whenever the computer goes idle or upon request, these processed go to foreground.

By simply changing the file extension of the demo applications from EXE to SCR, you can configure the Windows operating system to use them as screensavers and thus run them on the entire screen when you are away from the PC.

LineSpec will capture audio signal from the default recording device in Windows. The recorded audio signal is what determines the shape and size of  the generated animation.

The 'currently playing' function will show you the name of the song you are listening to and its lyrics, if available. However, this function is only available for a limited number of music players: Calaym, Apollo, WinAMP, AIMP, MusicBee.and MediaMonkey.
