SignalMetric: Audio Analyzer

LUFS Meter & Noise Monitor

$1.99 · Designed for iPad. Not verified for macOS.

Professional audio dashboard: LUFS, peaks, spectrum and waveform. Evaluate room noise; find silence, imbalance and clipping risks in audio/video. No ads or subscription. SignalMetric is a private audio analyzer for creators. Check a final export, monitor room noise, prepare a recording space, or inspect a live signal on iPhone and iPad. PROFESSIONAL AUDIO INSTRUMENTS Use Monitor, Spectrum, Timeline and Scope to inspect level, LUFS loudness, True Peak estimates, frequency content, spectral history and waveform. Switch views without interrupting the session and choose from six focused appearances. MONITOR ENVIRONMENT NOISE Watch A-weighted relative level, FAST response, LAeq, minimum and maximum values without creating an audio recording. Uncalibrated readings use dBFS(A). Route-specific calibration can provide an estimated dBA reference. SignalMetric is not a certified sound-level meter. CHECK AUDIO AND VIDEO Analyze up to 10 local files with progress and a separate result for each. Review loudness, estimated peaks, digital silence, channel balance and mono compatibility. Video checks use the first supported audio track. Completed reports remain available if another file fails or the batch is cancelled. PREPARE TO RECORD Compare a short room sample with your speaking voice from the same position. See relative digital level and input headroom before the real take. The setup check saves no microphone audio. COMPARE AND EXPORT Save measurements with titles and notes, compare two revisions side by side, and export readable PDF, CSV or JSON reports. Reports contain no source audio or file paths. PRIVATE BY DESIGN Audio analysis runs on device. There is no account, analytics, advertising, subscription or cloud media library. Live microphone audio stays in memory unless you explicitly tap Record. Optional feedback is sent only when you submit it. One purchase for iPhone and iPad.

SignalMetric 2.0 introduces a clearer home for publishing checks, recording preparation and revision comparison. New Environment Noise view shows FAST, LAeq, minimum and maximum levels without saving audio, with optional route-specific calibration for estimated dBA. The professional workspace now presents level, spectrum and waveform data in a denser instrument panel. File checks support audio, video and batches of up to 10 items, with actionable peak, silence, channel and loudness findings. Save results, compare revisions, and export PDF, CSV or JSON. English, Simplified Chinese, Traditional Chinese, Japanese and Korean are included.
