[1.17.0] - 2026-07-03

The fifth flagship — the audiophile moat. NewAmp's first native code.

Added

  • Bit-Perfect Exclusive (Windows). Settings → Playback grew the toggle the
    audio-quality doc used to call "future phase": true WASAPI-exclusive
    output through a first-party native engine (vendored miniaudio, N-API,
    native/newamp-audio/). When it's on, tracks bypass Chromium, Web Audio,
    and the OS mixer entirely — ffmpeg decodes straight to raw PCM in the main
    process and a lock-free ring feeds the DAC on the WASAPI callback thread.
    • Honest by construction. The stream format is negotiated from the
      device's native exclusive formats; if your DAC's clock can't run the
      source rate, NewAmp resamples explicitly (SoX, precision 28) and tells
      you       — it never ships miniaudio's hidden converter (which we caught
      silently resampling 44.1→48 k on real hardware during development, and
      now refuse at open time by comparing requested vs. internal format).
    • The gold badge. The transport's signal-path badge earned a fourth
      tone: gold EXCLUSIVE is the strict claim — lossless source, rate + bit
      depth + channel layout preserved, no DSD conversion. Anything less shows
      EXCLUSIVE* with the exact reason in the tooltip. 16-bit into a 24-bit
      device slot is still gold (zero-padding loses nothing); mono-to-stereo,
      rate conversion, or DSD→PCM honestly is not.
    • No DSP means no DSP. EQ, ReplayGain, crossfade, limiter, preamp and
      software volume are structurally out of the path and grayed in Settings
      with an explanation. Volume is your DAC's knob — same deal foobar2000
      gives you, now with the reasoning printed on the tin.
    • Visualizers stay alive. A 30 Hz playhead-aligned PCM tap flows from
      the native engine into a spec-faithful AnalyserNode emulation (Blackman
      window, 1/N FFT, -86/-10 dB byte mapping), so Eviland, MilkDrop, the
      detached projector, and Resonance react to exactly what the DAC is
      playing — proven by the gate: analyser energy with a silent Web Audio
      graph can only come from the native tap.
    • Gapless over exclusive. When the next track negotiates the identical
      device format, its PCM is spliced into the same ring at the exact frame
      boundary — no reopen, no gap. Rate changes re-open the device with a
      deliberate micro-gap (foobar2000 behavior). Pause releases the device
      after ~15 s so system audio comes back.
    • Falls back like a grown-up. Podcasts, cue-sheet segments, non-library
      files, a device that vanishes mid-track, another app holding the DAC —
      each falls back to the shared path per-track with the reason surfaced in
      Settings, never a silent dead toggle.
    • Gates: smoke:exclusive-output (addon: enum/probe/shared push, exact
      frame accounting; full exclusive HW pass behind
      NEWAMP_EXCLUSIVE_SMOKE_HW=1) and smoke:exclusive-ui (boots the real
      app, plays a FLAC through the native path, asserts exclusive engagement +
      clock advance + tap-fed analysers; earns (bit-perfect) on rate-matched
      hardware).

Fixed

  • Windows taskbar icon renders again. The 1.15.0 tray fix converted every
    ICO frame to BMP — including the 256 px frame that the taskbar/high-res
    shell path officially expects as PNG (the CHANGELOG even said the taskbar
    "looked fine" because it decoded PNG). build/icon.ico is now
    mixed-format (BMP < 256 for the tray, PNG @ 256 for the taskbar), rebuilt
    by the new committed scripts/rebuild-icon.mjs (do NOT use fix-logo.py —
    Pillow writes all-PNG and re-breaks the tray). Belt-and-braces: every
    BrowserWindow now sets an explicit window icon and the app declares its
    AppUserModelID (io.newamp.player) so taskbar identity/pinning resolve to
    our icon instead of a stale shell cache.
  • docs/audio-quality.md no longer recommends audify/RtAudio for the native
    path — RtAudio's WASAPI exclusive mode is an unimplemented TODO; the doc
    now describes the shipped miniaudio engine and the observed hidden-resample
    trap it refuses.

Verification: full release gate green (automatedOk) at this commit — 95+ smokes including the new smoke:exclusive-output and smoke:exclusive-ui end-to-end gates, real-library completion audit, packaged-app checks. Standing accepted blockers, same as every release: artifacts are unsigned (no Authenticode cert), Last.fm live proof and the human speaker/headphone pass are manual.
