Linear phase is a property of a filter, where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. And consequently, there is no phase distortion due to the time delay of frequencies relative to one another.
VLevel keeps your music from making you jump out of your seat, and it keeps you from having to fiddle with the volume constantly. It’s different from other dynamic compressors because it looks ahead. You can think of VLevel as someone who knows your music by heart, and turns the volume up during quiet passages, but smoothly turns it back down when he knows a loud part is coming. It’s great for making CDs to listen to in your car, or to play background music on your computer.
Adding scripts is one method used to extend Foobar’s abilities. Not only are there quite a few existing useful scripts, new custom scripts can be written. One great script is the Biography script which displays biography and rating information from both AllMusic and Last.FM
Enhance the appearance and functionality of Foobar2000 by adding a visual representation of the currently playing audio track, which can be used to navigate to any point in the image of the track by clicking there.
Waveform Seekbar is a UI element for both the Default UI and Columns UI that provides seekbar functionality (seeking, position indicator) on top of a pretty image of the waveform of the currently playing song, drawn using either Direct3D 9.0c or Direct2D 1.0.
Playlists, or named lists of songs, are an essential aspect of Foobar2000. Whenever you add a song to Foobar, you are essentially adding it to some playlist.
Playlists can be created manually by adding individual songs or automatically by specifying a set of conditions in a query with the result displayed as an “Autoplaylist”. Manually created playlists are static, they don’t change unless you change them, Autoplaylists are dynamic, that is, the results may change at times.
Playlists created manually can be edited directly, while Autoplaylists are edited by modifying the query. However, you can save the results of an Autoplaylist as a new static and therefore editable, playlist.
Creating an Autoplaylist of a Albumlist item like genre:
Select by genre from the Albumlist view selector
Select a genre from the list of genres
Right click that selected genre and select Create Autoplaylist
You will now have a new Autoplaylist listed on the playlist manager tab with the name of the genre you selected. Playlists created this way are called an Album List branch.
Creating an Autoplaylist of a folder’s contents:
Select the Search tab
enter %path% HASreplace this with the actual path in the search field
Select Create Autoplaylist
Rename the new playlist (with the path)
