  Riffer 4

  Audiomodern, with Atlantic Audio Development

  Commercially Released

  • Audiomodern (opens in a new tab)

  A MIDI generation and sequencing plugin with several generation engines, MIDI editing and interactive composition workflows.

  What I did

  As part of the Atlantic Audio Development team, I built and maintained JUCE interface components and interactive MIDI controls, and worked on the sequencing and randomization workflows, parameter controls and preset navigation. I also fixed undo-related and interaction bugs inside the established codebase, working through Git branches alongside other developers.

  QUANCE

  Codwaves, with Atlantic Audio Development

  Commercially Released

  • QUANCE product page (opens in a new tab)

  An audio processing plugin built around analysis-driven workflows, including a Learn function and loudness-related processing.

  What I did

  I investigated and corrected DSP bugs, reworked Learn so that newly learned frequency ranges replace earlier manual or preset ranges, and reduced transient overshoot in the loudness processing. I fixed GUI crashes around frequency-range interactions, investigated data races, and worked on interface freezes on Windows after display changes, which involved vblank synchronization and Direct2D rendering. I also built automated regression tests and validated the plugin across DAWs on Windows and macOS.

  WaveBalance

  Codwaves, with Atlantic Audio Development

  Commercially Released

  • WaveBalance product page (opens in a new tab)

  An auto gain staging plugin with real-time gain control, metering and a focused mixing workflow.

  What I did

  My work focused on correctness: verifying applied gain and metering, bypass and latency handling, the Static and Ride modes, and limiter and headroom behavior. I ran DSP null tests to confirm deterministic output and state recall, investigated transient overshoot, and validated the plugin across VST3, AU and AAX in Pro Tools, REAPER and Ableton Live.

• Plugin audits and engineering

  Confidential client, with Atlantic Audio Development

  Client projects

  Engineering and technical audits across several JUCE audio plugins for one client, including an instrument.

  What I did

  I audited plugin code for real-time safety, parameter behavior and host integration, and worked on the issues those audits raised.

  On the audio side the work covered real-time buffer handling, audio buffer and region safety, DSP correctness and high-sample-rate compatibility, together with plugin parameter behavior, host automation and parameter parsing.

  On state and host integration I worked on session restoration, plugin state serialization, host undo and redo integration and plugin lifecycle behavior, tested in REAPER and Ableton Live.

  Other reliability work included audio import and background processing, playback and loop reliability, offline license verification with persistence, fallback and consistency across plugin instances, a Windows UI freeze linked to display synchronization, and automated regression tests.

  LatencyFix

  LatencyFix, with Atlantic Audio Development

  Commercially Released

  • LatencyFix (opens in a new tab)

  A remote recording solution that keeps DAW sessions aligned for distributed collaboration. Artists in different locations can record together in one studio session, with every take landing in time, as if they were in the same room. Atlantic Audio Development's work on it includes Ableton Remote Scripts, Pro Tools PTSL automation and the product UI.

• Vocal chop instrument

  Undisclosed client, with Atlantic Audio Development

  In development

  A JUCE vocal chop instrument, as a plugin and a standalone app: it extracts the vocal from a recording, finds usable chops and maps them to pads and a keyboard.

  What I did

  I integrated the machine-learning stem separation used for vocal extraction: MDX and Mel-Band models running through ONNX Runtime on macOS and Windows, and a native Apple MLX implementation of the Mel-Band model covering the spectrogram, band split, chunked inference and weight loading. Separation runs as a background job with cached results.

  On top of it I built chop detection and ranking, the workstation interface with pads, waveform markers and keyboard, cleanup processing, tempo sync, and pitch and time processing with F0 detection and formant preservation, covered by Catch2 plugin tests.

  FIELDS

  Independent project by Carlos Garín, product concept by Alex Aller

  In progress, collecting sounds

  A sample instrument made to preserve sounds that are disappearing: recordings of protected animals and places, captured by recordists who travelled to remote locations to make them.

  What I did

  I developed FIELDS myself, from the sampler engine to the interface. Two sample layers each blend a clean and an excited version of a recording, with loops set over the waveform, envelopes, filter, delay and reverb, and a sound browser with search and presets.

• Polyphonic Guitar Tuner

  Personal project

  Machine learning research

  Musical note recognition using neural networks.

  What I did

  I developed a musical note recognition system based on fully connected neural networks in Python and TensorFlow, created the audio datasets used for training, and evaluated different network architectures.
