waveforms_audio 0.2.0

Customizable Flutter audio visualizers with Canvas and fragment-shader rendering for voice, music, and chat interfaces.

0.2.0

• Smooth wave and ribbon contours across frequency bands in both renderers.

• Redesign halo with rounded rays and bloom with a continuous petal silhouette; apply seamless spatial gradients across every palette stop.

• Give mirror spectrum a separated, fading reflection distinct from spectrum bars.

• Add streaming mono PCM resampling with controller output-rate selection, per-call source rates, and explicit tail flushing.

• Preserve up to four GPU gradient stops and use Canvas for longer palettes. Correct wave-layer palette positions to include the final color.

0.1.0

• Add a shared cross-backend fragment shader for orb, wave, halo, ribbon, liquid-orb, pulse-ring, and voice-bloom effects. Includes cached loading, automatic Canvas fallback, explicit renderer selection, and a public precache API.
• Add immutable audio snapshots and functional classic-bar spacing.
• Add PCM16, PCM24, and Float32 input formats with endian, multichannel, channel-selection, base64, and normalized-sample controller APIs.
• Add voice, music, ambient, and energetic motion presets with frequency-specific envelopes, adaptive gain, noise gate, peak hold, voice activity, and optional idle breathing.
• Add mirror spectrum, ribbon, liquid orb, pulse rings, dot spectrum, capsule bars, voice bloom, and minimal-line styles.
• Replace reactive constructor styling with immutable VoiceVisualizerStyle objects and keep canvas painters out of the main public entrypoint.

0.0.1

• Add upwardBars, voiceBars, and halo reactive styles.

• Add optional inactiveColor to reactive and voice-chat visualizers. By default, the active palette remains visible during silence; an explicit resting color enables energy-driven fading.

• Extend the example with a responsive six-style picker and active/idle palette controls.

• Allow independent local and remote gradient overrides in VoiceChatVisualizer, retaining preset defaults and smooth speaker transitions.

• Add VoiceChatVisualizer with smooth blue–cyan local and red–orange remote/AI speaker palettes, plus a reusable streaming Pcm16Decoder.

• Add opt-in microphone capture to the example, platform permissions, denied-access feedback, and cleanup on stop, background, or disposal.

• Add ReactiveAudioVisualizer with an organic orb, layered wave, and rounded logarithmic spectrum bars driven by PCM frequency energy.

• Add a rolling Hann-windowed FFT, fixed decibel scaling, and time-based attack/release envelopes with silence settling and reduced-motion support.

• Redesign the example with selectable frequency signals, visual styles, and pause.

• Seamless sinusoidal pulses that keep waveforms visible through the full cycle.

• Preserve animation progress during data updates and apply duration changes immediately.

• Ease amplitude updates with configurable transitionDuration (100 ms by default; use Duration.zero for immediate updates).

• Rotate oval waveforms as a whole and fit radial waveforms inside their bounds.

• Respect system reduced-motion settings and isolate waveform repaints.

• Reduce per-frame allocations; handle live stream replacement and window resizing.
