v1.0.0 - Initial Cross-Platform Release

MusicScope.NET v1.0.0

Initial cross-platform release of MusicScope.NET, a high-precision, open-source audio analyzer and acoustic measurement suite built on .NET 10 and AvaloniaUI 12.

MusicScope.NET provides 1:1 visual and mathematical parity with the original XiVero MusicScope v2.1.0 suite while delivering modern 60 FPS vector graphics, low latency, and cross-platform native performance.

Highlights & Features

Precision Signal Analysis

• EBU R128 / ITU-R BS.1770-4 Loudness Metering:
  • Integrated Loudness ($L_I$) with $-70\text{ LKFS}$ absolute and $-10\text{ LU}$ relative gating.
  • Momentary Loudness ($L_m$, 400 ms) and Short-term Loudness ($L_s$, 3 s).
  • Loudness Range (LRA) and S-Mode loudness distribution histogram.
• True Peak & Dynamic Range:
  • 4x Polyphase FIR oversampling filter for accurate inter-sample peak detection ($\text{dBTP}$).
  • Sample Peak ($\text{dBFS}$), RMS energy, CREST factor, and Peak-to-Loudness Ratio (PLR).
• High-Resolution FFT Spectrum & Waterfall:
  • Logarithmic frequency spectrum ($20\text{ Hz} - 48+\text{ kHz}$) with Blackman-Harris 92 dB side-lobe suppression.
  • Real-time 2D spectrogram waterfall heatmap.
• Stereo Goniometer & Phase Scope:
  • Vector scope with Mid/Side coordinate projection.
  • Real-time Phase Correlation Bar ($-1.0$ to $+1.0$) with mono compatibility warning zones.
• Polar History Dial:
  • 360-degree circular radar track history visualizer.

Hardware & Acoustic Measurement Modules

• THD Analyzer: Total Harmonic Distortion analysis via 1 kHz test sine wave, measuring harmonic bins ($h_2$ to $h_{10}$), attenuation, and SINAD.
• Jitter Analyzer: Clock jitter and sideband spur measurement using the Julian Dunn 11.025 kHz J-Test stimulus.
• Turntable RPM & Wow/Flutter: Speed tracking with 1000 Hz or 3150 Hz reference test records, measuring speed deviation $%$ and 2-sigma peak-to-peak wow/flutter.

Audio Pipeline & DAW Bridge

• Universal Audio Decoder: Streaming 32-bit floating-point audio decoding via native FFmpeg integration for WAV, FLAC, AIFF, ALAC, MP3, AAC, DSD (DSF/DFF), OGG, and Opus.
• DAW TCP Server: Built-in asynchronous socket server on port 8989 providing binary compatibility with DAW streaming plugins.
• Multi-Format Export: Export comprehensive measurement reports to CSV spreadsheets, structured JSON metadata, or formatted text files.
