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.

foo_dsp_vlevel ~ Dynamic Normalization

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.

Foobar2000 ~ Playlists & Autoplaylists

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:

  1. Select by genre from the Albumlist view selector
  2. Select a genre from the list of genres
  3. 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:

  1. Select the Search tab
  2. enter %path% HAS replace this with the actual path  in the search field
  3. Select ...
  4. Select Create Autoplaylist
  5. Rename the new playlist (with the path)

AutoPlaylist query examples:

Lossless ~ “$info(encoding)” IS lossless
Lossy ~ “$info(encoding)” IS lossy
Missing title ~ title MISSING (no percent signs)
Never played ~ %play_count% MISSING
No Dynamic Range info ~ %dynamic_range_album% MISSING
No ReplayGain info ~ %replaygain_track_gain% MISSING
No Album Artist info ~ %path% HAS album AND album artist MISSING
Played often ~ %play_count% GREATER 9
Randomly sorted ~ ALL SORT BY “$rand()”
Recently added ~ %added% DURING LAST 1 WEEKS
Recently played ~ %last_played% DURING LAST 1 WEEK
Recently modified ~ %last_modified% DURING LAST 2 WEEKS
