About Me

Andreas Wagner holds a master's degree (Dipl.-Ing.) in Media Technology with a specialization in audio-visual electronic media. With a decade of experience as a room acoustics consultant for international cultural venues, Andreas transitioned in 2015 to a second career as an audio-focused software engineer, driven by a renewed passion for technology research and development. In 2019, he joined the HD Vinyl project, marking his entry into the vinyl audio world with the Perfect Groove software. Since 2023, Andreas has been working as a full time independent software developer, currently focused on developing digital tools for the analog world of vinyl record production.

  • Geometry-Aware DSP for Vinyl Mastering

    Working Backwards from Physical Constraints
    00:00 - 00:00 UTC | Monday 9th November 2026 |
    Intermediate

    Mastering for vinyl is usually approached as an audio processing problem. In reality, the limiting factors are geometric: lateral and vertical modulation of the groove determine whether a record can be cut successfully, tracked reliably, and fit onto the disc in the first place. This talk introduces geometry-aware signal processing, a different way of thinking about mastering. By transforming the audio waveform into a virtual representation of the groove, we can measure the resulting physical geometry directly and apply processing only where it is actually needed, rather than relying on processing tools in the time or frequency domain. Using practical […]

  • The Shape of Sound

    Building and Bending Vinyl Grooves in Software
    15:00 - 15:50 UTC | Wednesday 12th November 2025 | Bristol 1
    Beginner
    Intermediate

    What does it take to turn an audio signal into the spiral groove of a vinyl record—and how can we simulate that process digitally? This talk explores the complete journey from sound to surface, starting with an overview of traditional analog disk cutting and how each step can be modeled in software. We'll look at how to generate a virtual groove—a digital, geometric representation of the modulated groove path—and how this opens up powerful new possibilities for analysis, playback emulation, and hardware interfacing. In the second part, the talk introduces a new open-source groove file format designed to standardize virtual […]
