You can associate foobar2000 with different file types at 'Preferences → File types' (Windows XP only) or access relevant control panel from 'Preferences → Shell Integration'.
Upgrading from any 0.9.x or 1.x version to the latest version will leave your settings intact, provided you install the new version on top of the old one.
Many old third party components no longer cooperate with newer foobar2000 versions. If you have any third party components installed, you should update them to their latest versions, or remove them one by one until you find the problematic component.
To install components from the foobar2000 installer that you did not choose to install during the initial installation, just rerun the installer and select them; your settings will be kept intact. Please read on to learn about installing other components.
Note that this content applies to foobar2000 versions 1.1 and newer. If you're using an older version, please upgrade now to utilize the new interface.
You should always download foobar2000 from its home page (foobar2000.org) and not from other sites. If you're experiencing suspicious activities after installing, we strongly recommend that you uninstall it immediately and scan your computer for viruses/malware.
There have been many reported cases of modified foobar2000 setups with pre-configured visuals and additional plugins included, which is - for good reasons - against the foobar2000 license. We have no control over such installers and can't provide much help regarding problems that you run into when using them. Many of them include outdated foobar2000 versions with known security vulnerabilities. People creating such installers are often only harming the community by scaring new users away with “pretty” user interfaces that are hard to use and ridden with bugs.
Please note that people affiliated with foobar2000 development never post announcements or files to other forums, software download or file sharing sites. As a result, we have no control over foobar2000 files that get posted to popular software download sites, and we have no intention of wasting our resources on verifying each case. If you've been led to believe that foobar2000 files on some site have been posted by the author himself, you're being lied to and this site should not be trusted.
Most technical problems can be solved by removing any third-party components and resetting the configuration (or doing a fresh reinstall). It is recommended that you backup your foobar2000 directory before doing that, so you can try to restore your old settings/components later, or help us with identifying the exact source of the problem.
Please disable any unneeded DSPs (such as resampler). Some of them require a lot of resources to operate.
Some DSPs such as crossfader or gap remover need extra memory buffers to operate; you can reduce the memory usage by changing their settings. Also, certain output modes (Kernel Streaming) have been reported to use excessive amounts of CPU time on certain systems.
Finally, some third-party components are known to use high amounts of CPU time.
Please post your question on the third-party component forum. As we don't take responsibility for components other people make, this FAQ can't help you any further.
The MP3 format doesn't natively support sample-accurate seeking, and sample accurate seeking is absolutely required by some features of foobar2000 (such as .CUE playback). MP3 seeking can't be optimized neither for CBR files (frame sizes aren't really constant because of padding used), nor for VBR files (both Xing and VBRI headers in those files contain only approximated info and are useless for sample-exact seeking). Therefore MP3 seeking works by bruteforce-walking the MPEG stream chain and is appropriately slow (this gets faster when you pass through the same point of file for the second time because seektables have been built in the RAM).
There are multiple reasons why this could happen. If there is no error message, the component has been banned - most likely for violating the foobar2000 SDK license. Otherwise please see the following list of error messages and the possible solutions for each.
You have installed foobar2000 in portable mode. The portable mode does not support Windows shell integration. You need to reinstall in standard mode in order to access relevant functionality.
Do not use alternate output modes unless you must. There is NO benefit in terms of audio quality to using these, as far as music playback is concerned ( read more on the subject ).
Additionally, on most systems, WASAPI (if available) is known to be more stable than ASIO.
Asus Xonar cards are infamous for their buggy drivers. We recommend getting a soundcard from another manufacturer instead.
If you're running foobar2000 older than 1.1.10, please update - version 1.1.10 introduces workarounds for certain known Xonar bugs.
Right-click one or more tracks, choose 'Properties' from the context menu. Various additional functionality can be accessed by selecting one or more fields in the Properties dialog and right-clicking them.
Note that you can mass-edit tags of a group of track by opening the Properties dialog on multiple items.
No. If you want to edit tags of multiple tracks, you can do it more efficiently by just selecting them all and opening the Properties dialog for them.
foobar2000 maintains the existing tags present in the file when it is possible to fit the information being written within these.
If the file does not already have tags that can hold the information being written, foobar2000 will add the ID3 tags necessary to store it.
Just use the 'Tagging → MP3 tag types' feature from the context menu. The dialog appearing is not an option dialog. The changes you are doing there are applied to the selected files only.
You have probably selected one or more non-MP3 files. The feature is only available for MP3 files.
Only ASCII characters are allowed in ID3v1. Any other characters are replaced by question marks on rewrites.
You can find this feature at 'File operations' from the context menu (you need to enable the 'Optional features → Tools → File operations' during installation).
Invalid file name characters - such as slashes or backslashes - are replaced before metadata originating from the file is processed by title formatting functions. This is necessary to allow slash or backslash characters placed by you in your file name formatting pattern to be interpreted as path delimiters without the side effect of each slash contained in metadata fields included in your file name formatting pattern being interpreted as a path delimiter as well.
Load tracks you want to convert into a playlist, right click, choose 'Convert' from the context menu, click one of sub-options. Converting functionality requires the Converter component to be installed ('Optional Features → Tools → Converter' during installation).
Note that converting to most supported formats requires external command-line encoders. Encoders for various popular formats can be easily installed with the foobar2000 free encoder pack. For the remaining formats, we recommend obtaining encoders from RareWares.
See Birthday paradox. Random mode doesn't prevent track repetitions other than the same track played twice in a row. You probably want to use 'Shuffle (tracks)' mode instead.
Shuffle modes keep an internal reordered list of tracks in your playlist. If you manually start playback from some track that you've already played, you'll get the same tracks played after it as last time. Use the 'Playback → Random' menu command to pick a random track in your playlist to resume from.
These modes can be used to reorder your playlist on album basis rather than track basis and play tracks in each album in sequential order. Shuffle (albums) is usable when your files are tagged properly (”%album artist% | %date% | %album%” evaluates to unique value for each of your album and doesn't vary between tracks in one album); Shuffle (directories) is meant as a fallback when your tagging scheme renders Shuffle (albums) useless but you keep each album in a separate folder. Note that the album identification pattern can be customized in 'Preferences → Advanced → Playback → Shuffle → Album grouping pattern'.
There are certain other sites claiming to be “official” foobar2000 sites in languages other than English. These sites are in no way affiliated with us. As we have no power over content of those sites, you should avoid using them as they may contain other misinformation or even malware.
Please choose 'Titleformatting Help' from foobar2000's 'Help' menu.
Right-click the status bar, toggle relevant option.
Enable “Cursor Follows Playback” under main window's “Playback” menu.
Go to 'Preferences → Display → Context Menu', right-click a group you want to add an entry to, select 'Insert item → Command…', choose the command you're looking for from the list. If the command you need can't be found, you're missing a component that provides it.
If the command you're looking for is already in the context menu structure tree under Context Menu Preferences yet you can't see it in your context menus, it might be context-sensitive and available only for specific tracks; for an example, MP3-specific utility commands are available only when all selected tracks are MP3 files.
Context menu commands require a list of tracks on which to operate. If you execute them from the context menu or using a normal (non-global) keyboard shortcut, this list is provided by part of the program where you used the context menu or the keyboard shortcut (the context). For global keyboard shortcuts there is no way to chose a list of tracks automatically when they are used, so you have to chose a context when you bind the command. To do so, select a command from the [context / now playing] or [context / playlist] branch to make the command use the playing track or the selected items on the active playlist when you press the global keyboard shortcut.
The FPL format is not meant to be interchangeable with other software or editable by users. Its primary design goals are carrying all necessary track information (metadata, last seen modification time, etc.) between foobar2000 sessions while remaining as fast to read and write as possible, since reading/writing FPL files bottlenecks app startup and shutdown with large Media Library or playlists. Making the FPL format user-editable would introduce massive startup/shutdown delays for certain users.
Additionally, the format is strictly tied to foobar2000 track information caching architecture; potential design changes in that area in future foobar2000 versions will inevitably require a new non-backwards-compatible revision of the FPL format.
The configuration file format is not meant to be interchangeable with other software or editable by users. Making it user-editable would result in third party component developers using it as an excuse not to provide proper user interface to change their components' settings, just like many components use title formatting as an excuse not to provide a more accessible way to customize them. Additionally, keeping the entire configuration file structure human-readable would result in slower startup/shutdown and code bloat as well as break compatibility with existing configuration files (or require even more bloat to import old settings).
No. Most of “sound quality differences” people “hear” are placebo effect (at least with real music), as actual differences in produced sound data are below their noise floor (1 or 2 last bits in 16bit samples). foobar2000 has sound processing features such as software resampling or 24bit output on new high-end soundcards, but most of the other mainstream players are capable of doing the same by now.
foobar2000 does not support any kind of translations. If you want a lightweight player with full multilanguage support, we recommend Boom.
