Description

Spectra is an app to create computational art from video and audio on iOS and Mac.

Settings files store the parameters that describe the art form and include:

• Control values
• Color palettes
• Audio samples

With built-in presets, video and audio samples you can generate cool art immediately! Then customize with your own settings, video and color palettes.

Many extra presets are available from within the app using ’Show More Settings’ in the File menu.

You can save settings in the ‘MySettings’ table of the presets pane, or in iCloud with 'Save Settings in iCloud' in the File menu. This enables sharing between iOS and Mac.

Saved settings and presets will include the current color palette - which you may have created yourself from the ‘Colors’ pane - and the current audio.

Video frames can be used for creating color palettes for drawing, and the audio is used to modulate line or arc length - the components of the paths Spectra draws.

A color palette generator is in the colors pane, where you also can quickly switch between video, settings file, variable, random or grayscale palettes. The variable palette generates color using a given color and a periodic trigonometric function. Generating colors in this way is fun with unlimited surprising results.

Visit the website for many examples, a demo and screenshots visually elucidating the simple process to transform video to art.

Using color and sound from videos various art forms are generated automatically with with attributes dependent on the values of user selected parameter controls.

Use your device videos, screen recordings or your favorite theatrical movies as input. You can use the audio of the video, or load a separate audio file.

The output can be printed from high resolution PNG images, or you can output the art as resolution independent PDF files to print at any resolution supported by a particular printer.

Spectra can be used as a platform for educators to integrate mathematical computation with creative art.

Although Spectra does not teach these concepts it can be used as a fun visualization and experimentation of applied math.

Numerous mathematical concepts can be introduced and illustrated through the art forms Spectra mathematically generates:

• transformations, functions, plots and parameters
• plane geometry: lines, triangles, circles, chords
• angles, rotation, trigonometry, radians
• distance, arc length, area
• randomness

4 basic art forms whose names are derived from the math:

• linear
• radial
• arc
• chord

Each Spectra graphic is merely a path composed of lines, circle arcs and chords. Each part corresponds to a particular frame of the video and sound level at the same time.

When using video as a color source every color is chosen as the average color of the frame.

Various other parameters you can adjust include:

• inner and outer radius
• zoom and 2 different arc length modes
• use of audio for line width and length modulation
• random, grayscale and parametrized color palettes
• random variability in frame selection ranges
• descriptive title label
• art aspect ratio
• line capping and width
• alpha gradient : the transparency of each part can diminish gradually over time so it is apparent what other parts it may overlap
• path filling to create solid pie shapes

To get a better glimpse of the variety of art you can generate peruse our website 'Gallery'.

For your convenience...

• Presets Table: Select from many control, color and sound settings sets. Then customize by changing the control, color and sound, say from another settings file.

• You can save your settings, including the colors and audio samples for reuse on both platforms.

• Two sample videos.

• Audio Samples: Additional audio files are built into the app, in particular many presets contain sample audio. This enables you to use the app "out of the box."

Enjoy!

Version history

1.5.6
2023-05-03
New solid background colors available in the 'Size' pane. Be sure to select 'Include In Spectra' if desired, otherwise the selected background only applies to the editor view.
1.5.5
2022-08-06
Multiple audio channel support added. Previously only the first audio channel was used.

Previous Updates:

Added HDR video support by converting HDR to SDR to improve colors; presents a reminder that you can set a background color for spectra videos from the Size view.

13 new presets have been added to the built-in settings library. Settings are available in the Presets tab. The Presets tab has two tables named Built-In and My Settings. These new presets appear in the Built-in settings, at the bottom. Your own settings are saved to My Settings.

126 new presets have been added to the built-in settings library. These were previously available from 'More Settings' and required individual downloads. This makes a large variety of presets readily available with ease.

NEW - Shadow option in the 'Lines' pane. This option will draw shadows for every line.
FIXED - After app relaunch the 'Play Waveform Audio' may sometimes play the wrong audio file.

New - When saving a spectra as a video you now have the option of including the audio, if available. The video duration will then match the audio duration. This can create a fun visualization of the audio.

New - Audio menu has new menu item named 'Share Waveform Audio' enabling you to send the waveform audio, if there is one, to an email, message, etc.

Fixed - Issue with audio processing that could prevent a settings file that uses audio from being restored to the correct look. It was due to a slight variation in audio modulation values. This issue was caused by changes in the last version.

• IMPROVED: Video color generation faster.

• NEW: Apply audio or set background image from Settings. ‘Apply Audio’ for audio, 'Set Background' for background.

• NEW: Playing audio shows its progress in the waveform graphic.

• NEW: When switching to settings without a background from one that does an option to remove the current background is offered.

• NEW: ‘Use Opened Audio’ menu item in the Audio menu: sets the current audio to the last audio imported from external apps (Files, iCloud, Messages, Music, etc) or internal samples.

• IMPROVED: The audio menu items 'Use Video Audio' and 'Use Settings Audio' are reimplemented for clarity.

• FIXED: Some audio files were not loading due to a mismatch of file extension and audio type.

• NEW: Option apply current background color to spectra when rendering. The background color is set in the Size pane.

• Other improvements.

Updated 'More Settings' web view. Use 'More Settings' to load additional settings from the web into the 'My Settings' table.

Fixed an issue with the 'My Settings' table where the table experienced inadvertent scrolling after selecting a setting. Updated for iOS 14.

FIXED: Saving background images to the Photos library now preserves transparency. In this way restoring a background from the photos library will restore the transparency, which is important for the mask mode of the Color pane.

Improved Performance: Settings data is cached to handle the increased load from incorporating background images and waveform audio files. Most notably the presets table scrolls more smoothly, but other methods that use settings data is faster.

Background Preview in Settings: The background image can be previewed from the user settings table. (Swipe on a row in iOS, right(control)-click on a row in macOS.)

Open Settings Options: Opening settings is more discriminate - if current settings has background, but new settings do not then an alert is presented because the existence of a background could mean the spectra does not look as expected unless you change the background settings.

Play Waveform Audio: The current waveform audio file can be played (if it exists; a waveform graphic only displays the audio samples, and its presence does not mean there is an audio file associated with it.) Select ‘Play Waveform Audio’ from the Audio menu. (Or on Mac use the ‘Play Waveform Audio’ button, and in iOS tap the waveform graphic)

• NEW: Option apply current background color to spectra when rendering. The background color is set in the Size pane.

• Other improvements.

Previous recent updates:

Updated 'More Settings' web view. Use 'More Settings' to load additional settings from the web into the 'My Settings' table.

Fixed an issue with the 'My Settings' table where the table experienced inadvertent scrolling after selecting a setting. Updated for iOS 14.

FIXED: Saving background images to the Photos library now preserves transparency. In this way restoring a background from the photos library will restore the transparency, which is important for the mask mode of the Color pane.

Improved Performance: Settings data is cached to handle the increased load from incorporating background images and waveform audio files. Most notably the presets table scrolls more smoothly, but other methods that use settings data is faster.

Background Preview in Settings: The background image can be previewed from the user settings table. (Swipe on a row in iOS, right(control)-click on a row in macOS.)

Open Settings Options: Opening settings is more discriminate - if current settings has background, but new settings do not then an alert is presented because the existence of a background could mean the spectra does not look as expected unless you change the background settings.

Play Waveform Audio: The current waveform audio file can be played (if it exists; a waveform graphic only displays the audio samples, and its presence does not mean there is an audio file associated with it.) Select ‘Play Waveform Audio’ from the Audio menu. (Or on Mac use the ‘Play Waveform Audio’ button, and in iOS tap the waveform graphic)

Apply Audio File Option: When opening settings with an audio file contained you have the option to ‘apply’ the audio file. File is read and stored as the current audio file for the waveform. So if the settings are changed and saved a copy of the same audio can be included. (Saved audio can be played from the user setting table.)

Save Audio Option: Saving settings presents the option to NOT save the current waveform audio file. Saving the audio file is for two purposes:

1. So that you can recall the audio by playing it from the user setting table.
2. So that if you load setting with an audio file you apply it so it may be included when saving a modified version of the settings.

New User Settings Table Row Labels: Labels in the user settings table indicate : contains audio data file, creation date and data size of the file.

New Labels & Colors For Clarity: New terminology adopted: ’Mask the spectra by the background image or vice versa. Implements 'white on alpha' masking, where white is transparent.' This is to emphasize the intended usage of the ‘White’ color in the color pane, and the use of the ‘Invert’ operation for masks.

Mask Inversion: Masks can be inverted. This is intended for use with ‘white on alpha masks’ - namely masks created as white with transparency. Choose the ‘White’ color option for a spectra and then save it as a background for masking. When inverted white pixels becomes transparent and transparent pixels become white.

Choose the ‘White’ color option for a spectra and then save it as a background for masking. When inverted white pixels becomes transparent and transparent pixels become white.

Background Color for Contrast: Since newer versions of Spectra enable coloring spectra with white it was hard to distinguish them when the default view background is white, therefore the default is now slightly ‘off white’ to provide contrast.

- The current audio data, as well as the processed samples for graphics modulation, is stored in a Spectra settings file enabling playing of the audio within Spectra.

To play the audio: In the 'My Settings' pane of Presets swipe across a row to display the row actions menu: Play, Rename, Delete and select 'Play'.

Note: When loading settings the audio data is not used to replace the current audio being used by Spectra. But since you can now play the audio that was the current audio at the time the settings were saved you can recall what it was.

- New isosceles triangle option, save Spectra to video, mask images by spectra, use images for color, composing spectra via backgrounds

*Note: the DPI of a spectra will vary based on available memory: if memory is limited the actual DPI may be less than the desired DPI. Use the ‘DPI Factor’ option in the ‘Size’ pane to extend the threshold for memory constraints if you need to print higher resolution than the default.

NEW - The ‘Video’ menu is now called the ‘Media’ menu because the use of media has been extended in a number of ways.

- Photos (including Live Photos) can be used for generating color palettes, as a supplemental method to using video for color.

When you use an image for color extraction the image will be subsampled for speed and given the inherent spectra limit of 2048 colors. In other words not ALL the colors in an image will be realized in the generated palette for the spectra.

If the media is a live photo then you still have the option to use its video as the color source.

- Photos (including Live Photos) can be used for as background images that appear under the current Spectra. This feature is primarily intended for composing multiple spectra graphics, because of the next new feature.

- A new menu item ‘Set Background Image From Spectra’ is a convenience method to set the background image to the current spectra. The intention of this feature is to easily enable composing multiple spectra into one.

- A new menu item ‘Set Background Image From Video’ is a method to set the background image from the current player video frame.

- A new menu item ‘Show/Hide Background Image’ to hide or show the current background image.

NEW - In the ‘Color’ pane there is a new hide/show option for the current background image.

New: Video generation can be saved as a video. From the File menu choose 'Save Spectra > Video'.

Features for generating new kinds of spectra graphics based on triangles, manage output metrics for improved print quality, setting background images and displaying a grid in the preview. Details:

NEW - In the ‘Lines’ pane there is a new option to draw a line as an isosceles triangle, either solid or outlined. This option has an associated size parameter which is controlled using the adjacent size slider.

NEW - In the ‘Size’ pane there is a new option to draw a grid in the preview. You can either turn the grid off, or set it to a blue or gray color. The grid size matches the current ‘Width’ and ‘Height’ settings: the number of grid spaces matches each dimension.

NEW - In addition to the new grid option to act as spectra guides for printing to fit specific sizes, the dimension label in the ‘Size’ pane will display the current spectra size in inches to 2 decimal places for printing to 300 dpi.*

NEW - After a spectra is generated (i.e. saving) an alert is displayed which shows the actual dimensions of the spectra in inches to 2 decimal places for 300 dpi.*

NEW - The ‘Video’ menu is now called the ‘Media’ menu because the use of media has been extended in a number of ways.

- The menu item ‘Live Photo Library’ is now called ‘Photo Library’ since you can now pick a photo or live photo for either a background image or color palette (see next items).

- Photos (including Live Photos) can be used for generating color palettes, as a supplemental method to using video for color.

When you use an image for color extraction the image will be subsampled for speed and given the inherent spectra limit of 2048 colors. In other words not ALL the colors in an image will be realized in the generated palette for the spectra.

NEW - In the ‘Color’ pane there is a new hide/show option for the current background image.

IMPROVED - the line dash length and spacing setting is restored when the app is relaunched.

StudentOfWork,
It’s a joke.
When I wanted to see my spectrum in didn’t pop or work.
Kittiypaws,
Umm....NOPE
Was not what I was looking for and didn't even work and didn't even get it and when I try to record nope and to see the spectrum nope nothing don't get it in my opinion
