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)
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
Last.fm is a web service that maintains a history of what you’ve listened to. You’ll need a Last.fm account and a player that can scrobble. Scrobbling is uploading the artist’s name and song title of your currently playing track to Last.fm’s server. foo_audioscobbler allows Foobar to keep your Last.fm profile current.
It replaces the Last.fm client application.
It supports the current submission protocol.
It sends “now playing” notifications to your Last.fm profile.
Optionally, it can import played tracks from your iPod via the foo_dop component.
After you install foo_audioscrobbler, you’ll need to log into your Last.fm account in Foobar’s Preferences menu.
Boom is an easy to use audio player intended for casual computer users who do not wish to spend their time on figuring more sophisticated software out. All of its most important features are easily accessible out-of-the-box.
You can extend Foobar2000s functionality by increasing the information the player maintains. Installing the foo_playcount component allows Foobar to both keep track of additional data, and adds the following user available fields:
Date and time a track was first played ~ %first_played%
Date and time a track was last played ~ %last_played%
The number of times a track has been played ~ %play_count%
Date and time a track was first added to the Media Library ~ %added%
Although rarely used, there exists the capability for standardized emphasis in Red Book CD mastering. As CDs were intended to work on 14-bit audio, a specification for ‘pre-emphasis’ was included to compensate for quantization noise. After production spec was set at 16 bits, quantization noise became less of a concern, but emphasis remained an option through standards revisions. The pre-emphasis is described as a first-order filter with a gain of 10 dB (at 20 dB/decade) and time constants 50 μs and 15 μs ~ http://en.wikipedia.org/wiki/Emphasis_(telecommunications)#Red_Book_Audio
Emphasis came about because of early converter design. The entire sampling process was new, and A to D converters exhibited low level noise because of bad linearity in the conversion process. This process added some high frequency broadband noise to the digital signal. Manufacturers overcame this byproduct by boosting (emphasis) the high frequencies during the conversion from analog to digital, and then rolling off (de-emphasis) the high frequencies by the same amount after the conversion back from digital to analog. This process was optional and there was a switch to select emphasis on each track during record. A flag was set in the digital bit-stream, which automatically activated de-emphasis during playback. All CD players, DVD players, and DAT machines detect this flag and turn on a high frequency roll-off in the analog domain during playback. If the digital signal contains emphasis and the flag is missing or turned off, then the roll-off does not occur and the audio will be brighter than normal.
This emphasis feature was the biggest reason why different CD players sounded different when playing back the same CD, or DAT machines differed playing back the same DAT tape. The digital part and the conversion to analog were basically the same in all of the machines. The de-emphasis circuit was implemented in the analog domain using the least expensive circuit to perform the operation. There was high-end EQ on the output of every digital playback device, and there was no standard or calibration for how it was performed. If you played back a CD without emphasis, then all of the CD players sounded pretty much the same. If you played a CD with emphasis, then each playback device sounded very different from every other player.
Producers and engineers started turning off the emphasis switches. Converters were getting better so there was less converter noise, and the use of de-emphasis circuits was eliminated. ~ Roger Nicolls
