A free, fully working sawtooth synthesizer for Unity. Real DSP, real presets, real sound. Try it before you buyNote: Not compatible with WebGL buildsSAWD Lite is a free, fully functional sawtooth synthesizer engine for Unity. No catch, no crippled output, no watermark just a working synth you can drop into a project today and start making sound with immediately.It exists because buying an audio plugin without hearing it in your project is a gamble.SAWD Lite removes that gamble entirely.A real synthesizer, not a demoLite is not a 30-second timeout or a feature stub. It is a complete synthesis pipeline: an anti-aliased sawtooth oscillator, a Cutoff Filter with four modes, a sub-octave oscillator blend, an LFO for filter modulation, and a full ADSR amplitude envelope. It is polyphonic, runs on the Unity audio thread, supports DSP-time scheduling for sample-accurate note placement, and handles voice stealing automatically when your voice pool fills up.For a lot of projects, this is genuinely everything you need.Try it in your project firstImport SAWD Lite, open the included Sound Stage demo scene, and you will have audio playing within a few minutes. Audition the bundled presets, tweak parameters live in the inspector, and trigger notes from your own code using a straightforward C# API. If the sound fits your project and you want more: more timbral depth, more expressive control, more sound-design tools the Pro edition is a direct upgrade with no migration work required.What you get in Lite- A complete sawtooth synthesizer engine ready to trigger from any game system- The AudioSourceBridge component for zero-config Unity audio routing- A bank of included presets covering leads, basses, pads, and effects- A Sound Stage interactive demo scene for auditioning and parameter editing- A clean C# scripting API: trigger notes, release them, schedule them ahead of time, and query voice state- Note this does not work on WebGL builds, it works on all Unity platforms that support onAudioFilterRead(), including mobile and consoles pure managed C#, no native pluginsWhat's waiting in ProSAWD Pro is where the sound design really opens up. Every preset you build in Lite plays identically in Pro upgrading adds new capabilities without touching anything you've already made.Is this right for your project?SAWD Lite is a strong fit if you need synthesized sound effects, UI tones, simple melodic lines, or a procedural audio foundation that responds to game state in real time. It handles polyphony cleanly, plays nice with Unity's Audio Mixer, and runs on every platform Unity supports.If you need thick layered pads, expressive bass lines with glide, or rich ensemble textures, those live in Pro. But start here hear what the engine sounds like in your scene, learn the API, and upgrade when you're ready.Core Engine (Lite)Real-time polyphonic sawtooth synthesizer, pure managed C#, no native pluginsScriptableObject-based engine, no scene lifetime dependency, survives scene loadsVoice pool of 1-128 voices, configurable per engine assetMain-thread to audio-thread command queue, no mutexes, no audio glitchesDSP-time scheduling for sample-accurate note placementMulti-stage automatic voice stealingTrigger token system prevents stale NoteOff events from cutting newer notesAllocation-free per-sample DSP loop, no garbage during audio processingSignal Chain (Lite)Anti-aliased sawtooth oscillator clean, bright, alias-free across the full pitch rangeSub-octave oscillator with variable blendCutoff Filter low-pass, high-pass, band-pass, and notch modesADSR amplitude envelope linear attack, exponential decay and releaseControl-rate LFO (triangle wave, 0.1–20 Hz) for filter cutoff modulationVolume and pitch offset (±24 semitones) per presetPreset SystemBundled preset library covering a range of lead, bass, pad, and SFX soundsCreate presets at runtime from code for procedural audio workflowsAudioSourceBridgeRoutes one or more engine assets through a standard Unity AudioSourceCompatible with Unity's Audio MixerPlatform and Version SupportUnity 2022.3 LTS and laterSupported platforms PC, Mac, Linux, iOS, Android, consolesNo native plugins, no third-party dependencies
