Editor-first waveform tool for trimming, fades, gain/pitch, stereo & LUFS, automations, bake to WAV with full Undo/Redo.
It lives entirely inside the Unity Editor so you avoid DAW round‑trips.NyxAudio is a fast, editor-first waveform tool that lets you repair, trim, fade, normalize, shape stereo, and bake to WAV—without leaving the Unity Editor. Built for speed: drop in an AudioClip and audition instantly with proper undo, real-time metering, and automated cleanup tools.Under the hood, NyxAudio runs a tiny preview graph in the Editor (hidden AudioSource + custom DSP), so playback is gapless, sample-accurate, and doesn’t require Play Mode.What you can doPlay/Edit: Scrub, Loop, and Zoom with a log-scale waveform. Smart auto-pan keeps the playhead in view.Automated Cleanup: The configurable One-Click Clean pipeline handles technical repairs (DC Offset, Fake Stereo) and aesthetic polish (Trim Silence, Smart Fades, Normalize) in a single pass.Batch Production Pipeline : Process dozens of clips simultaneously. Drag and drop a folder of assets into the Nyx Batch Processor to apply a standardized chain of Trimming, Smart Fades, SNR-aware Normalization, DC Offset Removal and Stereo Optimization in a single pass.Spectrogram Overlay: Visualize your audio's frequency content in real-time. Switch between Linear and Logarithmic scales, adjust dB intensity ranges, and choose from scientific palettes (Magma, Inferno, Plasma) or classic grayscale.Fades & Curves: Set Fade In/Out with Linear, Sine, Smoothstep, Power, or Custom curves (LUT-sampled for clean preview).Gain & Pitch: Preview Gain (dB) and Pitch (semitones) changes non-destructively.Envelope Automation: Draw a Gain Envelope with click-to-add points, lasso selection, tension control, and smoothing.Stereo Tools: Width 0–200%, Balance, Mono fold-down, Swap/Invert/Mute channels. Smart Stereo Optimization can convert identical stereo files to Mono to save 50% RAM.Meters: Peak & RMS, LUFS (Short-Term & Integrated), and stereo correlation/balance.Bake to WAV: Export your finalized clip as a 32-bit float WAV. Saving inside the Project triggers auto-reimport. Originals are never modified.Great for SFX, VO/dialogue cleanup, ambience trimming, music loops, and mobile optimization directly in the Editor.Core FeaturesEditor Interface: High-performance Editor window with smooth zoom/pan and sub-pixel waveform smoothing.Technical Repair: Intelligent DC Offset removal and Smart Stereo Optimization (automatic Mono conversion to save 50% RAM).One-Click Clean: A configurable pipeline that executes Repair, Trim, Fades, and Normalization in a single pass(Technical repairs optionally inlcuded).Batch Automation: A high-throughput pipeline for bulk asset processing. Features a dedicated UI for multi-clip drag-and-drop, allowing standard cleanup chains to be applied to entire folders simultaneously.Spectrogram Overlay: High-resolution frequency analysis with support for Logarithmic/Linear scaling, adjustable dB intensity, and scientific color palettes (Magma, Inferno, Plasma, Classic).Advanced Fades: Choose between Linear, Sine, Smoothstep, Power, or Custom curves, all driven by high-resolution LUT-sampled bias.Gain & Pitch: Adjust gain (dB) and pitch (±24 semitones via rate-change) with instant non-destructive preview.Envelope Automation: Intuitive Gain Envelope editor featuring lasso/multi-point selection, tension control, and point smoothing.Stereo Suite: Comprehensive control over Width, Balance, Mono-folding, L/R Swapping, Phase Inversion, and per-channel Muting.Professional Metering: High-accuracy Peak/RMS meters, LUFS (Short-Term & Integrated), and Stereo Correlation/Balance visualizers.Finalization: Sample-accurate baking to 32-bit float WAV with automatic project re-import.Compatibility & RequirementsUnity Versions: 2021.3 LTS or newer.Multi-threaded Performance: Spectrogram generation and DSP analysis utilize Parallel.For/Async patterns to ensure the Editor UI remains responsive during heavy processing.Platforms: Windows 10/11 and macOS 12+ (Full support for Intel and Apple Silicon).Render Pipelines: Fully agnostic—works with Built-in, URP, and HDRP.Zero Dependencies: No external Asset Store packages or DLLs required.Optimization: For the best experience, AudioClips should be set to “Decompress on Load” for instant previewing.Technical LimitationsPitch Shifting: Pitch adjustments are rate-change based (standard resampling); does not include granular time-stretching or formant preservation.Peak Readout: True-peak measurements are calculated as sample peaks with internal headroom estimation.Source Data: Requires readable PCM data. Encrypted or non-readable clips cannot be processed.
