E' NATA LA NUOVA APP DI O.ERRE. O.Tech è in grado di configurare e comandare i recuperatori di calore Ghost di O.ERRE installati all'interno della vostra abitazione in modo semplice e immediato anche se ci si trova lontano da casa. I vari recuperatori possono essere configurati automaticamente o in modo manuale così che si comportino come un unico sistema di ventilazione oppure possano essere gestiti come unità singole di ventilazione. Con O.Tech sono impostabili più di dieci differenti modalità di funzionamento (Automatica, Manuale, Sorveglianza, Smart, Fuori Casa, Espulsione Temporizzata, Notte, Immissione, Estrazione, Flussi d'aria) e quattro portate d'aria. O.Tech si collega alle centraline metereologiche per la rilevazione delle condizioni ambientali esterne ed è in grado di monitorare lo stato della qualità dell'aria dell'abitazione tramite un sensore VOC installato a bordo macchina.

Acoustic Analyser is a real-time audio measurement tool for musicians, technicians, and sound designers. It visualizes live microphone input in both the time and frequency domains, explicitly bypassing standard OS voice processing (like auto-gain and noise suppression) to give you an uncolored, accurate reading of your acoustic environment. Features: • Waveform & Spectrum Views: Monitor live audio blocks and view averaged magnitude spectrums on a log-frequency axis (20 Hz to Nyquist). • Accurate Peak Detection: Automatically identifies prominent frequencies with sub-bin precision and dynamic range gating. • Pitch & Harmonic Readout: Tap any peak to view its exact frequency, nearest equal-tempered musical note, cents deviation, and harmonic ratios. • Tone Playback: Audition isolated frequency peaks as pure sine waves with equal-loudness compensation. • Adjustable Parameters: Fine-tune your analysis with customizable FFT sizes, averaging modes (exponential or peak hold), and display offsets.
