v1.2.0

Phonalyser 1.2.0

The release that takes the measurement off the desk: a machine wired to your
converters can now run as a headless server, and both the desktop
application and the browser version measure through it as though the hardware
were plugged in locally.

Highlights

• The Phonalyser server - a headless application serving every audio
  backend on its machine (WASAPI, WDM-KS, CoreAudio, JavaSound, QA40x) to
  several clients at once: exclusive per-device locks that name the holder,
  multicast discovery, a two-second hardware rescan, console start or service
  install (Windows service, systemd unit, macOS launch agent). One ZIP per
  platform. No authentication, deliberately - it is a bench instrument for
  a trusted network.
• Measuring through it - a connected server's backends join the backend
  selector, and devices, cards, calibration, the generator, the sweeps and
  file playback behave as though local; a held device reads "in use by" with
  the holder's name. A server also serves the browser app itself at /.
• QA40x over WebUSB - the browser drives a QA402 / QA403 directly: full
  duplex at 48 / 96 / 192 kHz (384 kHz on a QA403), device-provided
  calibration, telemetry, and the experimental I2S port switch.
• Measurement additions - an amplitude histogram for the oscilloscope, the
  dBr magnitude unit (levels relative to the fundamental), output amplitude in
  dBFS, a cancellable sweep, and warnings for the two silent measurement
  killers: an uncalibrated device and a clipped sweep.
• Hardware volume is part of the measurement on Linux and macOS: every
  stream open pins the device to its own 0 dB, the close restores exactly what
  the pin moved. Windows stays untouched by decision.
• Fixed, among others - noise metrics pessimistic by the window's NENBW;
  A-weighting now per IEC 61672; device loss mid-measurement went unreported
  (macOS now ends both lanes and survives a replug without restart); macOS
  rate lists come from the device's declared formats; the pre-24.04 .deb
  refusal; bare-JAR installs without help and translations.

Install

• Windows - Phonalyser-1.2.0.exe (or the Microsoft Store); fat JARs
  phonalyser-1.2.0-windows.jar / -windows-x86.jar.
• Linux - phonalyser_1.2.0-1_amd64.deb, or phonalyser-1.2.0-linux.jar.
• macOS - Phonalyser-1.2.0-arm64.dmg (Apple Silicon) or -x64.dmg
  (Intel); JARs -macos.jar / -macos-x64.jar.
• Server - phonalyser-server-1.2.0-<platform>.zip for windows-x64/x86,
  linux-x64/aarch64, macos-x64/aarch64; runs on Java 17+.
• Browser - Chromium only (Chrome, Edge, Opera, Brave); nothing to
  install. The QA40x needs https:// or localhost and a WinUSB driver on
  Windows.

Builds are unsigned - see the per-OS README on the release page for the
first-run bypass (SmartScreen / Gatekeeper). An existing preferences.yaml
reads unchanged.
