PitchVis

Real-time visualization of musical pitches from live audio
新版本 1.30
New: PitchVis can now analyze the audio your phone is playing instead of the
microphone. Turn on "System Audio" in the debug screen (tap the visualization to
open it) and confirm Android's capture prompt. Audio only — no screen content is
captured and nothing leaves the device. Playback has to be running already,
since PitchVis stops when it goes to the background.

Fixes: the screen lock no longer engages when a system dialog interrupts a
touch, and the debug buttons no longer react while the s
PitchVis listens to your microphone and turns the musical pitches it hears into a colorful, real-time visualization.

Under the hood it runs a Variable-Q Transform (VQT) over the live audio signal, which gives high frequency resolution in the low registers where music lives, then detects the prominent pitches and maps each one to a color. The result is an animated picture of the harmony, melody and tuning of whatever you play or sing. It is displayed in a spiral, 12 pitches per octave, one octave per spiral rotation.

Features:

* Real-time pitch analysis of live microphone input
* Variable-Q Transform tuned for musical signals (especially choir singing)
* Pitch-to-color mapping in a perceptual color space
* Several visual modes (Full, Zen, Performance, Galaxy)
* Tuning drift display in cents
* Runs fully offline

PitchVis is useful for musicians, singers, music students and anyone curious about the structure of the sounds around them. It works with any instrument or voice.

PitchVis works fully offline and never connects to the internet. It uses the microphone permission for normal operation; the notification and foreground-service permissions are used only by an optional advanced mode that analyzes audio played by the device itself — audio only, never screen content.

    Ported the viewer to Bevy 0.19, which fixes the screen flickering seen on many
    Android devices (a missing-synchronization bug in the Vulkan renderer, now fixed
    upstream in wgpu). Lowered the minimum requirement to Android 9 (API 28).
