foo_vis_wispan is a Foobar2000 spectrum analyzer visualization implemented with GDI. It is a port of the Classic Spectrum Analyzer (vis_classic) Winamp visualization plug-in by Mike Lynch.
The foo_outinfo component exposes information about the current audio output and signal, such as the active output device, sample rate, bit depth, and channel count. These fields are especially useful in the status bar, where you want quick technical confirmation without cluttering playlists.
A simple and practical example is:
Now Playing: %artist% - %title% | %output_samplerate% Hz / %output_bitdepth% bit
What This Displays
When a track is playing, the status bar would show something like:
Now Playing: Miles Davis - So What | 44100 Hz / 16 bit
This tells you at a glance:
What is playing
The actual output sample rate
The output bit depth being sent to your audio device
Step By Step Explanation:
Music Metadata (Standard Fields)
%artist% - %title%
%artist% → Track artist tag
%title% → Track title tag
These are standard foobar2000 title formatting fields and work everywhere.
Separator
|
This is just plain text. It visually separates the music info from the technical output info. You can replace it with a dash, bullet, or brackets if you prefer.
foo_outinfo Output Fields
%output_samplerate%
Displays the actual output sample rate in Hertz
Reflects resampling, DSP changes, or output driver behavior
This is more reliable than %samplerate% when DSPs are active
%output_bitdepth%
Displays the bit depth used by the output
Shows what is being sent to the DAC, not just what is in the file
More Informative Versions
If you want to include channels and output device name:
Now Playing: %artist% - %title% | %output_samplerate% Hz / %output_bitdepth% bit / %output_channels% channels
Displays:
Now Playing: Aphex Twin - Xtal | 48000 Hz / 24 bit / 2 channels
If you want to add the current Replaygain mode:
Now Playing: %artist% - %title% | %output_samplerate% Hz / %output_bitdepth% bit / %output_channels% channels | RG %output_rg_source%
Displays:
Now Playing: Aphex Twin - Xtal | 48000 Hz / 24 bit / 2 channels | RG Album
If you want to display the active DSP
$if(%output_dsp%, | DSP: %output_dsp%)
Displays the separator and active DSP, otherwise displays nothing:
| DSP: Resampler (SoX)
Minimal Technical Version (Very Clean)
For users who want only output confirmation:
Output: %output_samplerate% Hz / %output_bitdepth% bit
Displays:
Output: 96000 Hz / 24 bit
Why Use foo_outinfo in the Status Bar?
Confirms what your DAC is actually receiving
Helps verify exclusive mode, resampling, and DSP behavior
Avoids cluttering playlists with technical data
Ideal for users who care about signal integrity but want a clean UI
Beginner Notes and Caveats
All output_* fields require foo_outinfo to be installed
These fields only show values while audio is playing
If nothing is playing, the fields will appear empty
OpenMusic (OM) is a visual programming language based on Common Lisp. Visual programs are created by assembling and connecting icons representing functions and data structures. Most programming and operations are performed by dragging an icon from a particular place and dropping it to an other place. Built-in visual control structures (e.g. loops) are provided, that interface with Lisp ones. Existing CommonLisp/CLOS code can easily be used in OM, and new code can be developed in a visual way.
OM may be used as a general purpose functional/object/visual programming language. At a more specialized level, a set of provided classes and libraries make it a very convenient environment for music composition. Above the OpenMusic kernel, live the OpenMusic Projects. A project is a specialized set of classes and methods written in Lisp, accessible and visualisable in the OM environment. Various classes implementing musical data / behaviour are provided. They are associated with graphical editors and may be extended by the user to meet specific needs. Different representations of a musical process are handled, among which common notation, midi piano-roll, sound signal. High level in-time organisation of the music material is proposed through the concept of “maquette”.
Partiels is an audio analysis application that allows you to explore the content and characteristics of sounds.
Features:
Partiels allows analysis of one or several audio files using Vamp plug-insloading data files, visualizing, editing, organizing, and exporting the results as images or text files that can be used in other applications such as Max, Pure Data, Open Music, etc.
Windows, Mac & Linux support
Multiformat support
Multichannel support
Multiaudiofile support
Analyzing audio with Vamp plug-ins
Visualizing results as spectrogram, lines, and markers
Loading results from CSV, LAB, JSON, CUE & SDIF formats
Batch processing
Command line interface to analyze, export, and convert results
Consolidating documents for sharing
Alongside Partiels, a wide range of analyses based on audio engines developed at IRCAM and outside are ported to Vamp plug-ins. These plug-ins allow you to perform FFT, LPC, transient, fundamental, formant, tempo, TTS and many other analyses. You can also find a large number of analysis plug-ins on the Vamp plug-ins website.
