Changelog

v0.1.0-alpha.8 (2025-11-16)

A precision release that locks in oversampling alignment, stabilizes intersample behavior, and moves the maximizer and stereo linking fully into the oversampled domain—while adding practical ref-level presets and streamlined licensing.

  • Licensing and activation: integrates licensing for streamlined activation and more reliable trial and full-license management across machines.
  • Maximizer in the oversampled domain: moves the maximizer stage fully into the oversampled path for tighter intersample control and more confident loudness pushes at the ceiling.
  • Stereo linking in the oversampled domain: stereo linking is now computed at the oversampled rate for a more stable stereo image and more precise channel coupling at high levels.
  • Timing alignment: corrects fractional-sample misalignment in the oversampling chain; improves latency reporting and guarantees coherent transients with no change to the frequency response.
  • Finer gain staging: adds reference level presets from 0 to −18 dB in 1 dB steps, with a default makeup gain of 1× and fine-resolution control.
  • UX polish: refines layout, tooltips, and small visual details to keep the interface focused on what matters most—meters, levels, and the music.

v0.1.0-alpha.7 (2025-11-06)

A major visual and workflow update that introduces a focused maximizer section, full VU/peak/crest metering, and a cleaner oversampling experience—wrapped in a redesigned UI tuned for fast, confident mastering moves.

  • New GUI: complete visual redesign of AL‑1 with a clearer layout, improved hierarchy, and a focus on key controls and metering.
  • Maximizer section: introduces a dedicated maximizer; adds an RMS-oriented maximizer option for a more “record-like” loudness feel when you want level that moves with the music..
  • Comprehensive metering: adds VU, peak, and crest-factor meters so you can balance tone, punch, and headroom without reaching for extra tools.
  • Oversampling workflow: introduces a dedicated oversampling factor control and consolidates all oversampling options into a single combo box for quick, predictable auditioning.
  • Smarter oversampling latency: computes oversampling latency analytically and keeps it aligned with unity-compensated LUFS metering for more predictable timing in your DAW.
  • Snapshot workflow: adds a snapshot copy button so you can duplicate settings between A/B slots without losing your current tweak.

v0.1.0-alpha.6 (2025-10-23)

This release focuses on polish and performance: faster and smarter A/B switching, improved latency, intersample‑safe limiting, lower CPU use, and a smoother, more reliable editing experience across all platforms.

  • Smarter snapshot switching: A/B switching is now instant when possible, with seamless transitions and no audible gaps unless latency changes are required.
  • Improved latency handling: AL‑1 now reports latency to the host immediately upon activation, preventing prefixed silence when oversampling is enabled.
  • Enhanced consistency: Unity gain alignment is now perfectly matched across oversampling settings, ensuring identical loudness when toggling OS on/off.
  • Safer limiting: improved internal peak detection for intersample safety and smoother, more stable gain‑reduction metering.
  • Performance boost: lower CPU usage under oversampling and improved efficiency during limiter processing.
  • Refined user input: text‑box edits on gain sliders now commit reliably without being interrupted by background updates.
  • Windows installer reliability: ensures old versions are correctly replaced during updates.
  • Overall stability: improved snapshot transitions, safer thread timing, and cleaner internal synchronization for a smoother experience across sessions.
