# Atlantic Audio Development > Specialist C++ audio software development agency. We build and ship audio plugins (VST3, AU, AAX) and audio software that perform — from idea to production-ready release. - Website: https://atlanticaudio.dev - Contact: info@atlanticaudio.dev - LinkedIn: https://www.linkedin.com/company/atlantic-audio-development/ - Based in Europe (CET), working worldwide with teams in North America and Asia. - Tech stack: C++, JUCE framework, Python (ML), PyTorch, TensorFlow, embedded audio. We help audio companies, musicians, and music tech teams ship high-quality C++ and JUCE products, without the real-time pitfalls that derail generalist developers. ## Who we help 1. **Audio software companies** — expanding product lines with plugins or standalone audio software, without the overhead of full-time hires. 2. **Musicians & producers** — with a plugin idea they want to bring to market, handled end-to-end from concept to commercial release. 3. **Music tech startups** — building serious tools and needing architecture that won't collapse the moment real users hit it. Whether you're starting from scratch or rescuing an existing product, we help you move faster and avoid the mistakes that derail most audio projects. ## What we build ### Audio Plugin Development (VST3, AU, AAX) We design and build professional audio plugins ready for real-world use. From concept to release, we handle the full development cycle: cross-platform plugins (macOS / Windows), VST3, AU, and AAX formats, JUCE-based development in modern C++, custom DSP and real-time audio processing, working reliably across Ableton, Logic, Pro Tools, and other DAWs.

We specialize in reducing CPU usage and improving efficiency, fixing crashes and edge-case bugs, optimizing real-time audio performance, and refactoring legacy JUCE / C++ codebases. We also offer a performance consultation: send us your plugin and we'll tell you exactly what's wrong and how to fix it — CPU bottlenecks identified, stability and crash analysis, architecture review with next steps. ### Audio AI & Machine Learning We integrate machine learning into real-time audio systems: audio analysis and event detection, generative audio systems, real-time ML pipelines, and integration with C++ and DSP workflows.

More: https://atlanticaudio.dev/audio-software-development.md ## Selected works A selection of public projects. Many engagements remain confidential. ### Playbeat 4 — Audiomodern End-to-end development of the full application and sequence randomization engine in JUCE and C++. Outcome: improved performance and stability across complex sessions, reduced CPU spikes, and eliminated crashes in high-load scenarios. Product: https://audiomodern.com/shop/plugins/playbeat/ ### Embedded Neural Network — Confidential client Model quantization, dataset curation, and tailored neural network architecture design for embedded hardware. Outcome: real-time execution on a 500MB RAM device while retaining a 95% F1 detection score. ### UI/UX Implementation and Maintenance — DiscoDSP Comprehensive UI rewrites and modernizations for OB-Xd, Discovery Pro, and Corona. Outcome: drastically improved visual feedback, smoother interactions, and a renewed lifespan for the plugins. Client: https://www.discodsp.com ### WaveBalance — CodWaves Auto gain staging plugin development with transparent real-time gain control, metering, and a focused mixing workflow. Outcome: a stable level-management tool for keeping tracks balanced before downstream processing. Product: https://codwaves.com/wavebalance/ ### LatencyFix End-to-end development including Ableton Remote Scripts, Pro Tools PTSL automation, and product UI implementation. Outcome: a remote recording workflow that keeps DAW sessions aligned and reduces friction for distributed collaboration. Product: https://latency-fix.com/ ### Djaminn App Audio-video synchronization development and targeted improvements to the app's audio engine. Outcome: a tighter mobile collaboration experience with more reliable media playback and recording alignment. Product: https://www.djaminn.com/ ## How we work 1. **Full product development** — from idea to release. We handle architecture, DSP, UI, and deployment. 2. **Team augmentation** — we integrate seamlessly into your team as senior JUCE developers to accelerate your timeline. 3. **Technical consulting** — architecture reviews, scaling advice, and strategic planning for your audio products. 4. **Optimization & rescue** — we jump in to fix existing systems, squash CPU spikes, and resolve stability issues.
