Filters vs Valdis

"Filters" is an application for the calculation of electronic filters for the construction of speaker systems. The program automatically calculates the values of electronic components (inductors, capacitors) of electronic filters depending by the desired speaker impedance and the cutoff frequency. The software can calculate and design the circuits (filters) for high, medium, low, sub woofer, etc... first and second order. Once calculated the filter’s circuit the app will automatically design for You the frequency and phase diagrams (Bode plots). Build the speakers of your dreams with "Filters"! Features: - Automatic calculation of the electronic components of the filters for high, medium, low, sub woofers etc... - Display of frequency and phase diagrams (Bode plots) for the calculated values of the circuit’s electronic components - Display electronic circuit’s schema (filter) - Complete theory for formulas/circuits for all the filters implemented in "Filters"

Valdis is an AI companion that keeps one conversation going across your Mac and iPhone — at home, on a walk, and offline. Valdis is built natively for macOS and iOS — no Electron, no fake web UI. At home, chat in text or voice — with your Mac doing the heavy lifting (local Ollama by default, with LM Studio as a local-first alternative). You can also send images in chat — pick from Photos, the camera, files, or paste/drag-and-drop. Valdis passes images to supported multimodal models so you can ask about what you see. When you step outside, switch to Walk & Talk for hands-free voice. On a plane or without internet, use Apple’s on-device model (Foundation Models) on supported Apple Intelligence devices. Back online, switch back to your Mac — or to a cloud provider you choose — and keep going without resetting. WALK & TALK (HANDS-FREE VOICE) - Real-time voice chat with on-device speech-to-text (WhisperKit) - Spoken replies (hands-free) - A 3D avatar with lip-sync and animations (RealityKit) CONTINUITY THAT DOESN’T RESET Keep the same conversation going across iPhone and Mac, so you don’t have to repeat yourself. APPLE ON-DEVICE (FOUNDATION MODELS) When Apple Intelligence is available, Valdis can use Apple’s on-device model for fast, private replies — even offline. Requires Apple Intelligence to be enabled in Settings. MAC-POWERED INFERENCE Run bigger models on your Mac and talk to them from your iPhone: - macOS runs local Ollama by default (LM Studio is also supported!) - Vision models are supported (so you can send images) when the selected provider/model supports it - Your iPhone can use your Mac for inference while you’re out REAL-TIME iPHONE ↔ MAC SYNC Keep your conversation in sync between iPhone and Mac when your iPhone is using your Mac as the provider: - Your Mac app hosts the server your iPhone connects to - Works over local network, VPN, or Tailscale LOCAL FIRST - No Valdis cloud: Valdis doesn’t have its own servers — sync happens only between your devices when you use your Mac as the provider. - Your Mac app can act as your backend (and sync host) when your iPhone uses it as the provider. - Cloud providers are opt-in and used for inference only. - Zero telemetry: no analytics, no crash reporting.
