Flat Liner Tuning release log.

Every release of the Flat Liner Tuning desktop app, what changed in each one, and what is landing in the next version.

  1. Version 1.0.1

    Current release

    Center channel tuning, a rebuilt Pro workflow, a new export target for Arc Audio processors, and a macOS build.

    • New Center channel support. Tune a center channel alongside the existing left, right, and subwoofer channels.
    • New Arc Audio filter support. Export your EQ as an Audison/Hertz 12‑band EQ file for use with Arc Audio processors.
    • New Mac version available. Flat Liner Tuning now ships a macOS build in addition to Windows.
    • Improved Pro version layout. The card view has been replaced with a searchable grid, so large setups are faster to scan and filter.
    • Improved Chart hover readout. Hovering the chart now shows the data point along with its X and Y axis values.
    • Fixed Duplicate car entries. Saving a new car no longer creates multiple entries.

  2. Version 1.0.0

    Previous release

    The first public release — the minimum viable product. The complete REW‑driven tuning workflow from measurement import through to the finished tuning report.

    • New Car and system setup. Define your vehicle, channels, and DSP so every calculation matches your install.
    • New REW measurement import. Pull your measurements straight from REW into the app.
    • New Target curve selection. Choose a target curve and EQ against it.
    • New EQ filter generation. Generated filters ready to enter into your DSP.
    • New Level matching and time alignment. Calculated per channel from your measurements.
