在 看见旋律 - WPF 实现音乐监听频谱图展示-CSDN博客 中我实现了对音乐旋律的监听把监测到的鼓点、低频通量等可视化看到了漂亮有趣的节奏线现在我们把它与常见的数学线条结合让节奏影响线条灯粗细、缩放、速度、跳动。整体处理流程把「音频状态 → 相位 → 采样点 → 归一化 → 绘制」串成一条线画廊里每个格子都走这段逻辑// Companion.WinUI3/Rendering/MathCurveGalleryRenderer.cs · DrawTile var influence MathCurveAudioBindings.ForEntry(entry, index, audioState); var linearPhase audioState.CyclePhase * entry.Speed; var phase MathCurvePhaseMapper.MapDisplayPhase(linearPhase, audioState.LoopMode); entry.Sample(phase, SampleBuffer, SampleCount); PrepareDisplaySamples(SampleBuffer, DisplayBuffer, SampleCount); ApplyBeatScalePulse(DisplayBuffer, SampleCount, audioState); DrawCurve(session, plotCenter, radiusX, radiusY, plotRect, linearPhase, audioState.LoopMode, influence); DrawTileLabel(session, entry, x, y height - labelBand, width, labelBand);音乐不直接改曲线公式而是改「相位推进速度」和「视觉强度」鼓点则触发脉冲包络// Companion.Core/MathCurveAudioModulator.cs · TickCore 摘录 if (driveChannel ! MathCurveDriveChannel.None isListening frame is not null) { channelRaw MathCurveChannelSampler.Sample(driveChannel, frame); channelNormalized Math.Clamp(channelRaw / _channelScale, 0f, 1f); _trendEstimator.Tick(channelRaw, dt, settings); speedMultiplier _trendEstimator.SpeedMultiplier; motionIntensity 0.35f channelNormalized * 0.45f; } _beatPulseTracker.Tick(dt, isListening, frame?.IsConfirmedKick ?? false, settings); _cyclePhase dt * baseRate * speedMultiplier; // 动画相位累积以下是 47 种漂亮的数学线条一起来欣赏吧漂亮的茅尓玫瑰送给你
