Checking a noisy restaurant, a concert, your AC or PC fans, road and traffic noise, a snoring partner, a baby's room, a workplace or machine shop, or a neighbour's music? Sono shows the sound pressure level (SPL) instantly with a clear live reading, an animated dial, and a scrolling graph. Why Sono • Fully offline. No account, no login.

A per-device calibration offset lets you trim the reading to match a reference. Features • Live decibel meter with a large, easy-to-read dB number • A, C and Z frequency weighting: dB(A), dB(C), dB(Z) • Min, average and max for every session • Real-time scrolling graph, from 30 seconds up to 30 minutes • Peak hold marker on the dial • Session timer with pause and resume • Calibration offset to match a reference level • Three gauge styles: circular, semicircular, and analog needle • Reference guide: how loud common sounds are, from a whisper to a jet • Save measurements with labels and notes, then browse your history • Add timestamped marks while measuring • Dark mode that remembers your choice, plus optional haptics • Lightweight and fast, opens straight to a live reading How Loud Is It? Quiet library ~30–40 dB · normal conversation ~60 dB · busy traffic ~70–80 dB · lawn mower ~90 dB · nightclub ~100 dB · rock concert ~110 dB. Sono labels the live reading against everyday sources so the numbers actually mean something. Great For • Checking whether a venue, restaurant or workplace is too loud • Settling neighbour noise disputes • Calibrating speakers, home theatre and audio gear • Measuring appliances, fans, engines and machinery • Anyone curious how loud their world really is A Note on Accuracy: Phone microphones are tuned for voice and can clip at very high volumes, so readings are approximate. Sono is a reference tool and is not a replacement for a certified sound level meter (SLM). Use the calibration offset to align Sono with a known reference for more reliable results. Sono is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Not a certified sound level meter, for reference only. Sono: the simple, offline decibel meter.

WaveTone Studio is a powerful mobile audio studio for iPhone and iPad. Import audio and video files, record directly with the microphone, edit waveforms precisely, and export results for music, clips, podcasts, ringtones, or quick audio ideas. Import MP3, WAV, M4A/AAC, AIFF, CAF, OGG, OGA, and Opus. You can also select compatible MOV, MP4, and M4V videos from Files or Photos. WaveTone Studio automatically extracts the audio track and loads it into the editor. Your audio is displayed as a clear waveform with zooming, scrolling, and a playhead. Pinch-to-zoom stays centered between your fingers. Place the playhead anywhere and start playback from that exact position. Selections show their start, end, and duration directly in the waveform, and both selection handles can be dragged for precise adjustment. A compact mini waveform remains visible while you scroll through the editor. Select ranges, select all, delete, trim, copy, paste, fade in or out, and adjust gain. VU meters with clipping indicators help you monitor levels. Silence Trim, Noise Reduction, and De-Click help clean up unwanted passages. Creative and technical tools include Pitch, Speed, Crossfade, EQ, Reverb, Delay, Normalize, Limiter, and generators for silence and noise. Export in common audio formats with options for bitrate, sample rate, and channels. Ringtone ranges can be selected, moved, previewed, and exported directly in the editor.
