Gleam - Stardance

Ship #1

@arth_mi on Gleam · about 1 month ago

Gleam is a FastAPI backend driving RGBW strips through a generic plugin API, so effects are built on exposed primitives (color, intensity, dim) rather than hardcoded. The tricky part was getting the architecture right first: syncing modules through a shared clock and separating color/intensity/white as distinct render layers. I’m especially proud of the Ambilight module, which captures HDMI output live and mirrors it onto the strip in real time, fully on-device with no cloud dependency.

Just finished a new module! The module is called audio_reactive and, as its name suggests, it reacts to the audio input provided (system default if parameter = None). It lights up the selected target as the sound gets louder.
It also features animations to make sudden transitions feel smoother.Here are the parameters for this module:

device: Audio input device name, or a portion of it (empty = system default)
color: Color of the light
min_intensity: Intensity when the input is silent [0.0 - 1.0]
max_intensity: Intensity at maximum volume [0.0 - 1.0]
sensitivity: Gain applied to the normalized level [0.1 - 5.0]
attack: Rise time in milliseconds (how quickly the light reacts to a louder sound)
release: Fall time in milliseconds (how slowly the light fades when the sound drops)

Rewrite the entirety of the Ambilight module for better functionalities
and performances. I wrote an advanced algorithm to get a smoother result
in addition to more parameters :

device_index
edge
reversed
band_depth_percent
weight_exponent
sample_overlap_percent
saturation_boost
-temporal_smoothing_tau

The main functionalities added are:

Advanced Color Averaging: Improved methods to calculate smarter average colors, such as sampling larger color bands or allowing LEDs to influence adjacent colors.
Temporal Smoothing: Introduction of “temporal_smoothing_tau” to ensure smoother, more natural color transitions over time.
Enhanced Immersion: Addition of “saturation_boost” and “weight_exponent” parameters to deliver a more vibrant and immersive visual experience.

For instance, the colors on the left terminal simulate the final result that would handle the left edge of the screen (using default parameters).

Just finished the main functionalities of the ambilight module of my LED controller. It takes a stream from the edge of the screen (HDMI to USB, for example), then processes each frame to get the average color of the surrounding area.
I’m still working on a blur effect that would give a less detailed result for a better experience.
(Sorry for the bad recording quality, this was made on an old laptop.)
