Foobar2000 ~ Installing Encoders, Decoders & Inputs

Posted by tom2tec on

Foobar2000 plays most audio files but can be extended. There is an official Encoder Pack which is a good place to start.

www.foobar2000.org/encoderpack

After downloading the latest version of the encoder pack, launch the installer and confirm it’s found the correct foobar2000 installation.

The next step is to deselect any encoders you don’t need.

And then click Install

Installing Additional Encoders

You may also need to install additional encoders; these are installed as components. For instance, foo_midi.fb2k allows foobar to play midi files. The component’s download page is here:

www.foobar2000.org/components/view/foo_midi

After you’ve downloaded the component, double click it and foobar should start the component installation procedure.

Click Yes and foobar will install foo_midi and require a restart. Once this is done, you should confirm that foo_midi was installed.

foo_enhanced_playcount ~ Enhanced Playback Statistics

Posted by tom2tec on

This Foobar2000 component collects and maintains enhanced statistics for played songs; primarily it records the timestamp of every play of a song, and not just the first and last. It will also query last.fm and record play times of every scrobble for a song.

foo_enhanced_playcount provides some additional functionality that foo_playcount does not, but is missing some functionality that foo_playcount has. They work well together, and foo_playcount should NOT be uninstalled when foo_enhanced_playcount is installed.

This component should be installed with foo_playcount and the same time foobar2000 is installed so playback statistics are maintained from the beginning.

New Fields:

  • %played_times% – Date formatted list: ["2012-08-04 15:58:37", "2012-12-10 14:40:46", "2018-01-02 23:38:13"]
  • %played_times_js% – JS timestamp list: [1344117517000, 1355172047000, 1514957893431]
  • %played_times_raw% – raw foobar timestamps: [129885911170000000, 129996456470000000, 131594314930000000] – There’s probably no reason to ever use this.
  • %lastfm_played_times% – Date formatted list of scrobbles: ["2012-08-04 15:58:37", "2012-12-10 14:40:46", "2018-01-02 23:38:13"]
  • %lastfm_played_times_js% – JS timestamp list: [1344117517000, 1355172047000, 1514957893000]
  • %lastfm_play_count% – Count of last.fm plays, a la %play_count%: 5
  • %lastfm_added% – Single date: “2012-08-04 15:58:37“
  • %lastfm_first_played% – Always exactly the same as %lastfm_added%. Use whichever one makes most sense logically
  • %lastfm_last_played% – Single date: “2018-04-04 15:58:37“
  • %added_enhanced% – Returns the earliest of %added% (from foo_playcount) or %lastfm_added%. Single date: “2023-02-04 15:16:17“
  • %first_played_enhanced% – Returns the earliest of %first_played% (from foo_playcount) or %lastfm_added%. Single date: “2023-02-04 15:16:17“
  • %last_played_enhanced% – Returns the earliest of %last_played% (from foo_playcount) or %lastfm_last_played%. Single date: “2023-02-04 15:16:17“

These fields can be exposed via Title Formatting or used in scripts. This component does generate extra data per song played and may not be suitable for installations with limited storage.

Foobar2000 ~ Installing A Component

Posted by tom2tec on

One of the reasons for Foobar2000’s versatility is extensibility. Its capabilities can be greatly extended by adding components.

For example, it’s good to keep track of information right from the start. An important first addition is playback statistics which are generated and maintained by foo_playcount.fb2k-component. Also consider installing foo_enhanced_playcount.

To add Playback Statistics to foobar2000, follow these steps:

  1. Download The New Component:
  2. Install The Component:
    • Go to File > Preferences, or press Ctrl + P.
    • In Preferences, go to Installed components on the left-hand side.
    • Click the Install button at the bottom of the section.
    • Navigate to and select the foo_playcount.fb2k-component file, then click Open and then Apply.
    • After installation is complete, foobar2000 will prompt you to restart.
  3. Verify Installation:
    • Once foobar2000 restarts, you should check File > Preferences > Components to confirm the component is now installed and active.

It’s also possible to install a Foobar2000 component by either dragging and then dropping a component on the component pane or double clicking a component if the file association is working.

The Get Updates button will download and update all the installed components but not Fobar2000 itself, that must be done via the Help Menu. It’s good to update the components occasionally.

The Copy Report button copies a list of installed components to the clipboard.

If the component has a visual element, you’ll also need to add the component to the DUI (Default User Interface) now. Toggle View\Layout\Enable Layout Editing Mode and then add a new panel or tab. Right click the new panel or tab area and select “Add New UI Element …“, then select the new component from the list. You may need to adjust borders to fit, then Exit layout mode.

The Playback Statistics Component keeps track of the following data:

  • Time/date first played
  • Time/date last played
  • Playback count
  • Time/date added to the Media Library
  • Rating

The Playback Statistics Component also allows playback statistics to be backed up or easily transferred to other Foobar2000 instances.

‘You can export playback statistics to an XML file and import them later, through Library => Playback Statistics menu commands, or through context menu on specific tracks. This can be used to easily transfer playback statistics between different foobar2000 installations or profiles.’ ~ XML Backup Functionality

foobar2000 version 1.6 required for compatibility with this component​

Hi-Res Audio For Android

Posted by tom2tec on

Enable high resolution audio for MediaTek devices up to 32-bit/192kHz (if device supports). This module only changes the configuration on “audio_policy” because most Android devices limit their capabilities to 16-bit/48kHz only, the rest depends on whether the device used supports Hi-Res Audio™ or not.

*applies to internal Speakers & Wired (not for Bluetooth/USB devices).
