🎧 [Name TBD] – Multiplatform DJ Software

I don't have a name for this yet — suggestions welcome!

A modern DJ application built on JUCE (Audio/DSP) and Qt 6 / QML (UI). Waveform rendering is fully hardware-accelerated via Qt RHI directly on the GPU using Vulkan – no CPU software rendering.

✅ Current Features

Feature	Details
Dual-Deck Playback	Two independent decks supporting FLAC / WAV / OGG / MP3
3-Band Waveforms	GPU-rendered waveforms with beatgrid overlay
BPM & Key Detection	Autocorrelation + Krumhansl-Schmuckler, Harmonic Mixing Format
Metadata Extraction	ID3v2 / Vorbis / M4A + filename fallback
Cover Art	Extracted via TagLib (MP3, FLAC, MP4, OGG, WAV)
Library Management	3-column panel, folder tree navigation, drag & drop to decks
Performance Pads UI	4×2 grid, 4 mode tabs (Hot Cue, Pad FX, Beatjump, Stems)
AV-Sync	Hardware latency compensation + sub-frame visual interpolation

🛠 Architecture (Brief)

JUCE Audio Thread  →  WaveformAnalyzer Thread  →  Qt Main Thread / QML
(Real-time audio)     (BPM, Waveform Bins)        (UI, Signals, Rendering)
                                                         ↓
                                                   Qt RHI → Vulkan (GPU)

These three threads communicate exclusively via Qt Queued Connections – zero direct cross-thread access ensures audio stability.

🐧 Linux-First

• Native Wayland support (Vulkan, no XWayland required)
• PipeWire / ALSA out-of-the-box without extra configuration
• All dependencies available via standard package managers

💻 Build Instructions

Dependencies: Qt 6, Vulkan, TagLib, CMake ≥ 3.22, C++20 Compiler

git clone --recurse-submodules https://github.com/TimoRams/multiplatform-dj-software.git
cd multiplatform-dj-software
mkdir build && cd build
cmake ..
make -j$(nproc)
./bin/MultiPlatformDJ

JUCE is included as a submodule under libs/JUCE/ – no separate installation required.
