We want to give audio developers a chance to create cool audio visualizations in their own apps and to be creative with audio signals and spectrums. This is why we've opened up a big part of our own library called **Spectrex**, free to use. 8 | 9 | Spectrex supports OpenGL and JUCE, and has already shipped in various software products out there. The library is shipped precompiled, compatible with CMake, and its examples are fully open-source and built using JUCE. The library can be used with other frameworks as well. 10 | 11 | 🚀🚀🚀 12 | 13 | #### Community Edition 14 | 15 | This repository is the Community Edition, and is meant for fancy visualizations with aesthetic value. 16 | 17 | The Community Edition is free to use in any application, and has the following features: 18 | 19 | * 🐥 _High-level interface_: 2D real-time pan/zoom spectrogram + waveform that are fully synchronized. 20 | * 🔮 _Low-level interface_: real-time processing that ties in with graphics APIs such as OpenGL. 21 | * 📚 _JUCE examples_: 2D spectrogram + waveform, 3D spectrum visualizers using custom OpenGL shaders. 22 | * 💻 _macOS and Windows_: Microsoft Visual Studio 2019, 2022 (Windows 7+) and latest Xcode (macOS 10.13+). 23 | 24 | #### Enhanced Edition 25 | 26 | If you're looking for more extensive applications involving accurate spectrum analysis, we also offer an Enhanced Edition. 27 | 28 | The Enhanced Edition contains a few more exclusive features intended for more extensive applications, such as: 29 | 30 | * 🌟 _FFT_: sizes up to 8192. (Community Edition: 256, 512) 31 | * 🌟 _Waveform_: Stereo (2x), Left, Right, Mid, Side views. (Community Edition: 1x downmixed waveform) 32 | * 🌟 _Override mode_: lets the Spectrogram and Waveform wrap from left to right. 33 | * 🌟 _Playhead sync_: syncs the Spectrogram and Waveform position with the DAW playhead and in bars. 34 | * 🌟 _Signal metering components_: CorrelationMeter, Goniometer and more visualization components. 35 | * 🌟 _Customization_: More customization functions and properties for various classes. 36 | 37 | Contact us to find out more. 38 | 39 | ### Documentation 40 | 41 | For documentation, refer to the code (extensively documented), any included generated documentation, or the examples. 42 | 43 | ### Licensing 44 | 45 | When including the precompiled libraries into your released products, please make sure to include the third-party attributions in `LICENSE.txt` somewhere in your software, installer or distribution. 46 | 47 | The examples in `examples` are licensed using the open-source MIT license. 48 | 49 | ### Examples 50 | 51 | ![Viz2DApp](docs/examples/viz2dapp.png) 52 | 53 | The `examples` directory contains two examples built for JUCE: a real-time 2D spectrogram and waveform visualizer (`Viz2DApp`), and a real-time 3D spectrum visualizer using custom OpenGL shaders (`Viz3DApp`). 54 | 55 | ### Get in touch 56 | 57 | Visit https://koaladsp.com or check out our [Discord](https://discord.gg/QndSN2w74S). 58 | -------------------------------------------------------------------------------- /cmake/macos/Spectrex-debug.cmake: -------------------------------------------------------------------------------- 1 | #---------------------------------------------------------------- 2 | #

Spectrex SDK in your own app, using the JUCE 7.x framework. 4 | 5 | All of these examples can be built as standalone, VST3, VST2, AU, AAX or other formats using JUCE. 6 | 7 | #### Viz2DApp 8 | 9 | A real-time 2D spectrogram application with a spectrogram and waveform. 10 | 11 | ![Viz2DApp](../docs/examples/viz2dapp.png) 12 | 13 | The app uses the high-level `KComponent` classes provided by the SDK, so you don't have to implement your own analyzers and meters. 14 | 15 | * Fully synchronized spectrogram and waveform. 16 | * Live parameter tweaking. 17 | * Zooming and panning, lets you zoom into the data. 18 | * Start and stop functionality. 19 | 20 | #### Viz3DApp 21 | 22 | A real-time 3D spectrum application that uses GL shaders to visualize the audio spectrum in different creative ways. 23 | 24 | ![Viz2DApp](../docs/examples/viz3dapp_1.png) ![Viz2DApp](../docs/examples/viz3dapp_2.png) ![Viz2DApp](../docs/examples/viz3dapp_3.png) 25 | 26 | The app uses a lower level approach that lets you build your own shaders to visualize the synchronized spectrum data yourself. The examples includes vertex, geometry and fragment shaders to adjust. You can build any type of shader that leverages the real-time spectrum data, knock yourself out! 27 | 28 | * A few colourful and retro 3D spectrum visualizers. 29 | * Custom shaders to process incoming spectrogram data. 30 | * Live parameter tweaking. 31 | -------------------------------------------------------------------------------- /examples/Viz2DApp/CMakeLists.txt: -------------------------------------------------------------------------------- 1 | # Product 2 | juce_add_plugin(Viz2DApp 3 | COMPANY_NAME "KoalaDSP" 4 | COPY_PLUGIN_AFTER_BUILD TRUE 5 | FORMATS Standalone VST3 6 | PRODUCT_NAME "Viz2DApp" 7 | PLUGIN_NAME "Spectrex 2D Example App" 8 | IS_SYNTH FALSE 9 | NEEDS_MIDI_INPUT FALSE 10 | NEEDS_MIDI_OUTPUT FALSE 11 | IS_MIDI_EFFECT FALSE 12 | EDITOR_WANTS_KEYBOARD_FOCUS FALSE 13 | 14 | MICROPHONE_PERMISSION_ENABLED TRUE 15 | MICROPHONE_PERMISSION_TEXT "This app needs permissions to use your microphone." 16 | HARDENED_RUNTIME_OPTIONS com.apple.security.device.audio-input 17 | ) 18 | target_compile_definitions(Viz2DApp 19 | PUBLIC 20 | # JUCE 21 | JUCE_VST3_CAN_REPLACE_VST2=0 22 | ) 23 | set_target_properties(Viz2DApp PROPERTIES 24 | XCODE_ATTRIBUTE_CODE_SIGN_ENTITLEMENTS "${CMAKE_CURRENT_SOURCE_DIR}/entitlements.plist") 25 | 26 | # Sources 27 | target_sources(Viz2DApp 28 | PRIVATE 29 | # Headers 30 | PluginEditor.h 31 | PluginProcessor.h 32 | Parameters.h 33 | Utility.h 34 | WindowOpenGLContext.h 35 | ParameterWindow/ParameterWindow.h 36 | ParameterWindow/ParameterDisplay.h 37 | UI/Cursor.h 38 | UI/Visualization2DComponent.h 39 | UI/VisualizationComponent.h 40 | 41 | # Sources 42 | PluginEditor.cpp 43 | PluginProcessor.cpp 44 | WindowOpenGLContext.cpp 45 | ParameterWindow/ParameterWindow.cpp 46 | ParameterWindow/ParameterDisplay.cpp 47 | UI/Cursor.cpp 48 | UI/Visualization2DComponent.cpp 49 | UI/VisualizationComponent.cpp 50 | ) 51 | 52 | # Link dependencies 53 | target_link_libraries(Viz2DApp 54 | PRIVATE 55 | # Spectrex dependencies 56 | Spectrex 57 | glm 58 | GSL 59 | glad 60 | $<$:ipp> 61 | 62 | # JUCE 63 | $ 64 | $ 65 | $ 66 | ) 67 | -------------------------------------------------------------------------------- /examples/Viz2DApp/ParameterWindow/ParameterDisplay.h: -------------------------------------------------------------------------------- 1 | #pragma once 2 | 3 | // Plugin 4 | #include "../Parameters.h" 5 | 6 | // GLM 7 | #include 8 | 9 | // Stdlib 10 | #include 11 | #include 12 | #include 13 | #include 14 | #include 15 | #include 16 | 17 | struct ParameterType 18 | { 19 | enum Type 20 | { 21 | SLIDER, 22 | COLOR, 23 | TOGGLE, 24 | BUTTON, 25 | COMBO_BOX, 26 | };
