This version is functionally identical to v0.4 but uses GitHub Actions for automated cross-platform builds.

Choose the download that matches your operating system and hardware:

• windows_x64 - for Windows (64-bit)
• macOS_x64 - for macOS Intel (e.g. older Macs)
• macOS_arm - for macOS Apple Silicon (M-series chips)
• linux_x64 - for Linux (64-bit)

Note: Only the Windows build has been tested locally. The macOS and Linux builds were generated automatically from the same source code using GitHub Actions.

What's Changed

• Added Norm Factor slider to manually control spectrogram brightness
  • Useful for adjusting visualization to match signal loudness (e.g. soft vocals vs. strong beats)
• Added two new enhanced colormap modes: Grayscale+ and Magma+
  • These modes use custom multi-stage brightness mapping to improve contrast in low and mid dB ranges
  • Makes it easier to visualize subtle spectral detail and transient energy spikes

Note: This release (v0.4) doesn't include prebuilts for Linux or macOS yet. If you're able to help build and test on those platforms, I'd love to hear from you! Feel free to drop a message in [Discussions] (or anywhere you like).

Full Changelog: v0.3...v0.4

What's Changed

• Add Spectral Centroid overlay in Linear STFT mode, visualizing spectral brightness in real time
• Add MIDI note display in hover readout (C4 = Middle C)
• Add dB floor slider to control minimum brightness threshold for color mapping

Update 19.07.2025: Added plugin for Linux. Thanks to @FranklyFlawless from the KVR Audio forum for building and testing on Debian 12 Bookworm (DAW: Ardour 8.12.0).

Full Changelog: v0.2...v0.3

What's Changed

• Add Mel-frequency cepstral coefficients (MFCCs) mode

Full Changelog: v0.1...v0.2

This release is functionally identical to v0.1, but replaces the Projucer-based build system with CMake-based workflow.
