Select Microphone to visualize audio from your microphone instead of the music player.
Microphone input is only accessible to the browser in a secure context, i.e., if you’re accessing audioMotion via localhost, local file (open index.html directly) or HTTPS protocol.
If your sound card supports Stereo mix mode, this should be listed as an input device when access to your microphone is requested. The Stereo mix input allows audioMotion to read audio generated by any program running in your PC.
Please note that the visualization from microphone or stereo mix audio might suffer from a slight delay.
You can use the player controls to play, pause and skip through queued songs.
The Shuffle button shuffles the queue and starts playing it from the beginning.
When the Repeat option is active, the player will loop back to the first song after playing the entire queue.
Click the Fullscreen Analyzer button, or press the F key, to display the spectrum analyzer in fullscreen.
You can use the keyboard shortcuts below to control the player and change some settings without leaving fullscreen:
|Left / Right||J / K||play previous / next song|
|Space||play / pause|
|Up / Down||Shift+G / G||select previous / next gradient|
|Shift+A / A||cycle through auto gradient and random mode options|
|B||cycle through Background options|
|Shift+B||cycle through background Image Fit options|
|D||display current song info - press again for settings info|
|E||shuffle play queue|
|F||toggle fullscreen mode|
|H||toggle FPS display|
|I||toggle song info display on track change|
|L||toggle LED effect on analyzer bars|

|O||toggle low-resolution mode|
|P||toggle peaks display|
|R||toggle play queue repeat|
|Shift+S / S||click on analyzer||toggle display of frequency and level scales|
|T||toggle flat text option|
|U||toggle luminance bars effect|
|Shift+X / X||select previous / next reflex style|
Panels are accessed by clicking the Settings, Files, Console and Config tabs.
Several options of color gradients for the analyzer bars. You can change gradients with the Up and Down arrow keys, or alternatively, G and Shift + G keys.
If the AUTO switch is on, the next gradient will be selected on track change, cycling through the available gradients. When Random mode is active, a random gradient will be selected on every mode change.
Selects the analyzer background.
- Gradient default uses the background color defined by the currently selected gradient - when the LED effect is on, this shows the “unlit” LEDs instead;
- Black uses a black background;
- Album cover displays the album cover for the current song. See also Image Fit and Image Dim settings.
You can cycle through the available options using the B keyboard shortcut.
Album covers are preferably retrieved from song metadata. When a picture is not found in the metadata, audioMotion will look for jpg, png, gif or bmp files in the song’s folder, and will use any image which filename contains the words cover, folder or front (in this order), or the first image found otherwise.
When Background is set to Album cover, this option selects the size and positioning of the image.
- Adjust - resizes the image so it fills the entire canvas;
- Center - displays the image horizontally centered on the canvas (default);
- Pulse - makes the image pulsate to the beat of the song;
- Repeat - repeats the image horizontally to fill the canvas;
- Zoom In - image is initially centered on the canvas and slowly zooms in as the song plays;
- Zoom Out - image is initially enlarged at 200% and slowly zooms out as the song plays.
You can cycle through the available options using the Shift + B keyboard shortcut.
When Background is set to Album cover, this option adjusts the brightness of the background image.
Selects a reflection style for the analyzer. This setting has no effect when the LUMI switch is active.
Selects which scale(s) should be displayed in the analyzer axes:
- Frequency (Hz) scale, displayed on the horizontal axis (default);
- Level (dB) scale, displayed on the vertical axis (not shown when LUMI or RADIAL switches are active);
You can cycle through the available options using the S and Shift + S keyboard shortcuts, or clicking on the analyzer canvas.
- INFO toggles the on-screen display of song information on every track change
- PEAKS shows amplitude peaks for each frequency
- FLAT applies an outline instead of shadow on text displayed on canvas - may improve performance, depending on your graphic card and browser
- LO-RES reduces canvas resolution to improve rendering speed (especially useful for 4K+ displays)
- FPS displays current framerate at the top right corner
The underlined character in each switch label indicates its keyboard shortcut, when available.
Selects the visualization mode.
- Discrete frequencies mode allows you to visualize individual frequencies provided by the FFT;
- Area graph displays the same frequency data as above, but as a filled area graph;
- Line graph connects all the discrete frequency points in a continuous line and allows you to customize the line width and fill opacity;
- Octave bands modes display wider vertical bars, each one representing the nth part of an octave, based on a 24-tone equal tempered scale.
You can also select the visualization mode using the M and Shift + M keyboard shortcuts.
Bar Spacing can be configured when any octave bands mode is selected. Avaliable options are:
- Legacy (minimum spacing between analyzer bars);
- Narrow (10% of bar width) (default);
- Regular (25% of bar width);
- Wide (50% of bar width);
- Extra wide (75% of bar width).
These settings can be configured when Line graph mode is selected.
Line Width controls the thickness of the outer graph line, while Fill Opacity adjusts the transparency of the graph area.
Select additional visualization effects.
- LEDS toggles the vintage LED effect for the analyzer bars (octave bands modes only)
- LUMI toggles the luminance bars effect - analyzer bars are displayed always at full-height, varying their luminance instead (octave bands modes only)
- RADIAL displays a circular spectrum analyzer with radial frequencies (disables both LEDS and LUMI)
When RADIAL is active, you can also configure its spinning speed.
The visualization mode and some other settings may be randomized on track change or time interval.
The lowest and highest frequencies you want to see in the graphic spectrum analyzer. You can use this feature to “zoom in” a specific frequency range.
Number of samples used for the Fast Fourier Transform performed by the analyzer.
Higher values provide greater detail in the frequency domain (especially for low frequencies), but less detail in the time domain (slower response to changes), so you may also want to adjust the Smoothing if changing this.
Average constant used to smooth values between analysis frames.
Lower values make the analyzer react faster to changes, and may look better with faster tempo songs and/or larger FFT sizes. Increase it if the animation looks too “jumpy”.
Adjusts the analyzer sensitivity to improve the visualization of songs too quiet or too loud. You can also use the N and Shift + N keyboard shortcuts.
The presets can be customized in the Config Panel.
The Demo preset will pick new visualization settings when loaded and will set random mode to 15 seconds, so it’s a great way to quickly overview all of audioMotion’s features!
Full resolution, LED bars and Octave bands presets provide quick configuration recommendations.
Any changes to the settings will be automatically saved to your browser’s localStorage and restored the next time you open audioMotion. You can manually load the Last session preset to undo any changes made during the current session.
The Restore defaults preset resets all options to their initial values, as in the first time you run audioMotion.
Save a favorite configuration in the Custom preset, by clicking the Save button.
The file explorer allows you to navigate through the music folder shared by the server.
Double-click a music file or playlist to quickly add it to the queue. Press Ctrl to select multiple files, or Ctrl+Shift to select a range of files.
Click the Add selected button to add selected files to the queue, or the Add all files button to enqueue all music files in the current folder.
You can also drag and drop files from the file explorer into the play queue.
Supported extensions are flac, m4a, mp3, ogg and wav for music files, and m3u or m3u8 for playlists. Codec support may vary, depending on your web browser and operating system.
Any image file found in the current folder will be shown in the background of the file explorer, giving preference to filenames containing the words cover, folder or front (in this order).
Double-click a queued song to play it.
You can drag and drop queued songs to reorder them. Press Ctrl to select multiple files, or Ctrl+Shift to select a range. Press Delete (Backspace on Mac) to remove selected songs from the queue.
Clear clears the queue. Save as… saves the queue as a new local playlist, stored in your browser’s local storage.
Saved playlists appear in the playlist selection box. Select a playlist and click the button to load it into the queue. Press the button to update the selected playlist with the current queue contents. Press the button to permanently deleted the selected playlist.
The console records several useful information, like audio and video settings, configuration changes and error messages.
