Spektral

Beschreibung

Spektral is a professional real-time audio analyser for sound engineers: identify feedback, measure system response, characterise room acoustics and monitor noise compliance. FIVE ANALYSIS MODES • RTA: live spectrum on a logarithmic 20Hz to 20kHz scale, above a scrolling time-frequency spectrograph with adjustable range and history • Transfer Function: dual-channel H1 estimator with magnitude, phase, coherence, impulse response and Auto-EQ • SPL Monitor: environmental noise compliance with Leq tracking and professional PDF export • RT60: reverberation across octave bands (125Hz to 4kHz): T20, T30, EDT and R², via interrupted pink noise or an impulse • STIPA: Speech Transmission Index to IEC 60268-16 with per-band MTF and SNR, a built-in test signal and a Bad to Excellent rating RINGING OUT • Ring-Out watches for feedback as you push the system and names the frequency the moment it starts to grow, not once it howls • Every confirmed ring lands in a session list with a suggested notch and Q, ready to copy to the console • Steady tones and hum can't trigger it: a frequency must be growing to be called • Identify labels the most prominent peaks on demand, from the single strongest to the top six PRECISION TOOLS • Selectable FFT size from 2,048 to 16,384 points • Cursor with parabolic interpolation for sub-bin accuracy, with musical note readout • Peak hold with smooth decay, and snapshot compare to overlay a frozen trace for A/B • Smoothing from 1/1 to 1/24 octave; frame averaging up to 32, plus infinite • Zoomable axes, floating mic/reference meter and per-channel input meters • Pink noise generator with adjustable output level SPL MONITORING & COMPLIANCE • A-, C- and Z-weighting, and Slow, Fast and Impulse time weighting, to IEC 61672 methodology • Calibrate via reference meter or acoustic calibrator, remembered per device and per input channel, and it survives an interface moving port • Gain tracking: change preamp gain mid-show and the calibration follows, so readings stay true without recalibrating • Rolling Leq windows: 1, 5, 10, 15, 30 and 60 minutes, plus 8-hour • Limit Guard: set a limit and see the window level, the zone, and how long before you reach it • Session statistics with time-history graph, and PDF reports carrying metadata, equipment and calibration detail TRANSFER FUNCTION & MULTI-POSITION CAPTURE • Works with a two-channel interface, or with just your Mac and a mic using built-in pink noise as the reference: no loopback, no interface • Impulse response (linear and ETC) with automatic reflection detection: arrival time, distance and level • Comb-filter prediction overlaid on the magnitude trace • Delay alignment: FFT-based detection, a guided wizard and manual sub-sample tuning • Phase shown against the delay you locked, compensated to sub-sample precision, so it compares position to position and tool to tool • Multi-position capture with quality scoring, weighted averages and per-capture PDF pages • Auto-EQ: up to 6 parametric suggestions with smart gain limiting REMOTE MONITORING (add-on) • Deploy iPhones as wireless SPL monitoring stations at multiple points • Live Mac dashboard showing SPL, Leq and peak for every site, with a satellite map and heat propagation overlay • PDF compliance reports with a page per remote location • iCloud sync: no servers, no accounts, no configuration. One-time purchase, all your devices DESIGNED FOR PROFESSIONALS • Dark interface for low-light environments, with single-key shortcuts for the controls you reach for mid-show • Smooth, low-CPU rendering that stays responsive through a long session • Works with any Core Audio input device. Native SwiftUI, launches instantly Monitor off-site noise propagation at live events, track occupational exposure in studios, characterise room acoustics and verify speech intelligibility. The workflow professional acousticians use, in a native Mac app. Spektral is not a certified Class 1 or Class 2 instrument.

A few users had experienced a crash with the new Sub Alignment wizard. This fixes that issue.
