SoundCoach vs SoundMaster Pro

Running sound at your church or small events without formal training? SoundCoach is the assistant standing next to you at the console. MEASURE IN REAL TIME • Decibel meter (dB SPL) with session history and color zones, so you know when volume is safe and comfortable. • Full-screen 31-band spectrum analyzer (RTA): see exactly which frequencies dominate your mix. • Feedback detector: an alert tells you which frequency is taking off before the squeal ruins the moment. DESCRIBE THE PROBLEM IN YOUR OWN WORDS "Sounds boxy", "too metallic", "can't understand the vocals", "it booms". No technical vocabulary needed — pick tags or write it the way you hear it. GET CONCRETE ADJUSTMENTS AI combines your description with the real analysis of your room's sound and gives you prioritized steps: which frequency to EQ (with exact gain and Q), how to set the compressor or gate, and what to do with effects. Every adjustment comes with a plain-language explanation of what will improve. PRIVACY FIRST Audio never leaves your phone. All sound processing happens on your device; only numeric analysis data goes to the cloud. No sign-up, no accounts, no personal data. BUILT FOR VOLUNTEERS SoundCoach was born for sound operators at churches and small events: people who serve with heart and learn on the go. Measurements are approximate (iPhone mics aren't calibrated instruments), but more than enough to make better mixing decisions. The free tier includes the meter, the spectrum analyzer, the feedback detector, and a limited number of AI recommendations per month.

Sound Master — acoustic measurement for live-sound engineers: sound level meter, spectrum analyser, RT60, system response and speaker delay alignment. Usable results in seconds, in the field, offline and with no account. Built for the field Sound techs, system engineers, installers: every tool answers a real situation — finding a hole in the response before the audience arrives, checking an RT60, aligning a delay tower, tuning a system. Mic-based readings are indicative, not calibrated: a field tool, not a lab. On iPhone and iPad Real-time sound level meter in decibels. Real-time spectrum analyser, full-resolution FFT or octave bands from 1/1 to 1/12, with peak hold and RMS curve. RT60 measurement (T20 method). Signal generator (sine, white noise, pink noise, log sweep). Swept system response. Speaker delay alignment. Saved captures that can be compared against each other and exported to PDF. On Mac — additionally A Mac has an audio interface plugged into it, and the Mac edition uses it. Live mode: meter, analyser and spectrogram side by side in one window, each panel resizable and adjustable on its own. dB A and dB C over fifteen minutes, microphone calibration, limits that turn red when exceeded, a trend indicator. Session recording to PDF minute by minute, and instant screen capture to PDF. Input routing: each bus is assigned to any input of any device, from inside the app. The MIC bus carries the measurement — it is what the meter, the analyser and the spectrogram all read. The optional REF bus carries the reference signal and appears as an extra curve on the analyser with its own scale, draggable so it can be laid over the measurement for comparison. The two buses can come from two different boxes: the app builds its own private aggregate device with clock drift correction, adding nothing to your system settings and never touching Audio MIDI Setup. Subscription Free trial, then subscription. The subscription is shared across iPhone, iPad and Mac — one purchase covers all your devices. On Mac there is no ad-supported free tier. About level readings The meter gives working figures for the sound engineer, dependent on your microphone's calibration. It is not a regulatory sound level meter: a legally valid measurement requires a class 1 or 2 instrument per IEC 61672. In a venue subject to noise regulation, the venue's own system is what counts.
