  • Simple and intuitive interface
  • Highly accurate beat simulation
  • Accent the first beat in a measure
  • Preset tempos include Largo, Allegro, Presto and more
  • Visual beat indicator bar provides a helpful visual cue
  • Create accurate beat patterns for simple or complex rhythms
  • Subdivide beats to hear difficult patterns, such as triplets

AutoEQ ~ Automatic Headphone Equalization


AutoEQ is a project for equalizing headphone frequency responses automatically and it achieves this by parsing frequency response measurements and producing a equalization settings which correct the headphone to a neutral sound. This project currently has almost 2000 headphones covered in the results folder. See Usage for instructions how to use the results with different equalizer softwares and Results section for details about parameters and how the results were obtained.

AutoEQ is not just a collection of automatically produced headphone equalization settings but also a tool for equalizing headphones for yourself. frequency_response.py provides methods for reading data, equalizing it to a given target response and saving the results for usage with EqualizerAPO. It’s possible to use different compensation (target) curves, apply tilt for making the headphones brighter/darker and adding a bass boost. It’s even possible to make one headphone sound (roughly) like another headphone.

Third major contribution of this project is the measurement data and compensation curves all in a numerical format except for Crinacle’s raw data. Everything is stored as CSV files so they are easy to process with any programming language or even Microsoft Excel.

SoundTouch ~ Audio Processing Library


SoundTouch is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or audio files. The library additionally supports estimating stable beats-per-minute rates for audio tracks.

  • Tempo (time stretch): Changes the sound to play at faster or slower tempo than originally without affecting the sound pitch.
  • Pitch (key) : Changes the sound pitch or key while keeping the original tempo (speed).
  • Playback Rate : Changes both tempo and pitch together as if a vinyl disc was played at different RPM rate.

The SoundTouch library is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects.

The SoundTouch library source kit includes also an example utility SoundStretch for processing .wav audio files from command-line interface.

Access the source codes in gitlab or download the compiled executables.

Introduction: What Title Formatting Is

Title formatting in foobar2000 is a system that allows you to control how information about your music is displayed in the interface. It doesn’t modify the audio files themselves or change tags — it only affects how metadata and other information is shown in playlists, status bar, or window title.

Think of it like a template language: you define a pattern for text, and foobar2000 fills in the fields with actual track information. For example, you can make the playlist display tracks as:

Artist - Track Title (Album)


Why Title Formatting Exists

Music files contain metadata such as:

  • Artist
  • Album
  • Track title
  • Track number
  • Year
  • Duration

Different users want to display this information differently. Title formatting lets you:

  • Decide which information to display
  • Choose the order of information
  • Add separators, labels, or punctuation
  • Optionally display certain information only when it exists

For example, you might want to show the album only if it exists. Title formatting makes that possible.


Where To Use Title Formatting

You typically use title formatting in three main places:

  1. Playlist columns — to customize how each column displays track info.
  2. Status bar — to show the “Now Playing” track in a readable format.
  3. Window title — to display the currently playing track in the foobar2000 window or taskbar.

Core Concepts You Need to Know

There are three core concepts that beginners must understand:

  1. Plain Text: Text you type exactly as it should appear.
  2. Fields: Metadata values from the audio files (e.g., %artist%, %title%).
  3. Conditional Logic: Optional logic to handle missing fields or customize output dynamically.

Plain Text in Title Formatting

Any normal text you type is displayed exactly as written. This is useful for labels, punctuation, or separators:

Now Playing:

You can combine plain text with fields to make output more readable:

Now Playing: %artist% - %title%

This will display something like:

Now Playing: Radiohead - Paranoid Android


Fields (Metadata Tags)

Fields are placeholders that pull metadata from your music files. They are written inside percent signs:

%artist%

Some common fields include:

FieldMeaning
%artist%Track artist
%album%Album name
%title%Track title
%tracknumber%Track number
%date%Year or release date
%length%Track duration

Example combining fields:

%artist% - %title%

Output:

Radiohead - Paranoid Android


Combining Plain Text and Fields

You can mix plain text with fields to create more structured output. For example:

%artist% – %title% (%album%)

Output:

Radiohead – Paranoid Android (OK Computer)


Handling Missing Information

If a field does not exist in the file, foobar2000 simply displays nothing. For example, if %composer% is missing:

%composer%

The output will be blank. To prevent blank parentheses or awkward spacing, you can use conditional logic.


Using Conditional Logic with $if()

The $if() function allows you to display text only when a field has a value:

$if(condition,then,else)

Example:

%artist% - %title%$if(%album%, (%album%),)

This will display the album in parentheses only if %album% exists. Otherwise, it leaves that part empty.


Practical Examples

Playlist Column

%artist% - %title%

Status Bar

Now Playing: %artist% – %title%

Window Title

%artist% – %title% | foobar2000


Useful Built-In Fields

These fields are always available and do not require files to be tagged:

FieldMeaning
%filename%File name
%path%Full file path
%codec%Audio codec
%bitrate%Bitrate
%samplerate%Sample rate

Things Beginners Can Ignore

  • Nested functions
  • Math expressions
  • String replacement logic
  • Legacy syntax
  • Advanced grouping

Starter Setup for New Users

For someone just installing foobar2000, start with these basic formats:

%artist% - %title%

Now Playing: %artist% – %title%$if(%album%, (%album%),)

%artist% – %title%


Final Notes

  • %field% is the most important concept
  • $if() handles missing or optional data elegantly
  • Some data and fields depend upon components being installed

foo_tfsandbox

A good place to start is by installing foo_tfsandbox, this component allows you to experiment with title formatting expressions and fields before you implement them.

Title Formatting Fields:

$info(referenced_offset) ~ shows time in format mm:ss:ff where ff are CD frames. For the first track it will show nothing instead of 00:00:00
hydrogenaud.io/index.php?topic=118733.msg979344

Title Formatting Examples:
Name | Pattern | Alignment

Display Dynamic Range:
Album DR: $if2(%album dynamic range%,–) | Track DR: $if2(%dynamic range%,–)
Bits (bit depth) | $ifequal([%__bitspersample%],0,16,%__bitspersample%) | Left
$if($or($stricmp(%codec%,DTS),$stricmp($cut(%codec%,3),DCA)),$if($info(bitspersample),$ifequal(%samplerate%,96000,$ifgreater(%bitrate%,1537,DTS-HD,DTS 96/$info(bitspersample)),DTS-HD),DTS),%codec% [%codec_profile%])
Release Date (earliest):
$max(%DATE%,$min($year(%DATE%),$year(%DISCOGS_RELEASED%),$year(%DISCOG_MASTER_RELEASE_DATE%)))
