Auralize vs LeDrum

Auralize is an acoustic measurement tool for iPhone that combines sound level meter and decibel meter features to measure, record, and document sound levels in the field. Built by acoustic and computer engineers, Auralize uses a calibration correction factor obtained in a laboratory. Up to 4000 Hz, the app qualifies as a Class 2 measurement, delivering reliable accuracy for technical fieldwork. Track sound levels in dB(A) in real time, view the equivalent level (Leq), the maximum level, and sound pressure (SPL) data with acoustic weighting. During measurement, follow sound variations on a chart updated in real time. More than measuring, Auralize helps you keep the full context of every measurement organized — from the field record to the final report. REAL-TIME MEASUREMENT Track sound levels in dB(A), the equivalent level (Leq), the maximum level, and sound pressure (SPL) information throughout the measurement. MEASUREMENT CHART See in real time how the sound level varies over the measurement and clearly follow how the environment behaves. AUDIO RECORDING Save the measurement together with a WAV-format audio recording, keeping a sound record of the analyzed moment. MEASUREMENT WITH CAMERA Perform acoustic measurements with photo and video, combining visual context with sound recording and real-time acoustic, location, and time data. PHOTOS AND LOCATION Add photos and location information to measurements, including coordinates and city, to record the context of every analysis carried out in the field. PROJECT ORGANIZATION Group your measurements into projects and keep an organized history to review past records and results whenever you need. PDF REPORTS Gather the data recorded during measurement into PDF reports ready to review and share. FROM MEASUREMENT TO REPORT Sound levels, charts, recordings, photos, location, and results stay organized in a single flow, making acoustic measurement work simpler and more complete. Measure. Record. Organize. Share. Terms of Use and Privacy Policy By using Auralize, you agree to the app's Terms of Use and Privacy Policy.

LeDrum is a precision drum tuner for iPhone. It listens to each hit, detects the fundamental frequency in real time, and shows the exact pitch in Hz — so you can tune every lug to the same note and get a clean, consistent sound across your whole kit. Built for drummers, not guitarists. Drum hits are short, percussive, and full of overtones that trip up ordinary tuners. LeDrum locks onto the fundamental inside the noise of a real strike. HOW IT WORKS 1. Place your iPhone near the drum. 2. Choose the frequency range that fits the drum. 3. Tap near each lug and read the frequency. 4. Adjust each tension rod until every lug matches. THREE FREQUENCY RANGES - Low (65–120 Hz) — bass drum and floor toms - Broad (20–450 Hz) — full kit and rack toms - High (245–400 Hz) — snare WHY DRUMMERS USE LEDRUM - Real-time frequency readout in Hz, plus the nearest musical note - Live spectrum visualizer — see the strike, don't just hear it - Lug-to-lug tuning for even tension and clear tone - Works across the whole kit: kick, snare, toms - Clean, distraction-free display built to read at a glance FREE & PRO Start free with a daily tuning session.
