SpettroLive

About

SpettroLive turns your iPhone into a real-time spectrum analyzer and helps you get rid of feedback, ringing and boomy sound in meetings, conferences, presentations and small events. LIVE ANALYZER - Spectrum from 20 Hz to 20 kHz on a logarithmic scale, updated in real time - Numbered peaks with frequency, level and musical note - The spectrum is split into zones: choose how many peaks to show and each zone displays its own, from lows to highs - Peak hold line with adjustable hold time from 0.5 to 5 seconds - Freeze the graph to read it calmly - Optimized for both portrait and landscape FIX AUDIO - Detects feedback and howling, room resonances and 50/60 Hz electrical hum - For each problem it suggests the cut in dB, the Q factor for a parametric EQ and the nearest band of a 31-band graphic EQ - Analyzes voice balance and flags boominess, muddy or harsh sound - 1/3-octave bars with the bands to fix highlighted - Share a report with the frequencies to fix GUIDED RING-OUT Slowly raise the microphone gain: SpettroLive records every frequency that starts to ring and tells you how to cut it on your mixer. Your system is ready in minutes. WHO IT'S FOR Sound engineers, speakers, teachers, event organizers, meeting rooms, churches, clubs and anyone using a microphone and speakers. PRIVACY Audio is analyzed on the device only: nothing is recorded or sent. Available in English, Italian and German. Note: levels are in dBFS and do not replace a calibrated sound level meter; suggestions are a guide and should always be checked by ear.
