APM Sweep vs TonalSnap

APM Sweep is the successor of the well known APM Tool: it let you quickly measure the acoustical performance of a room (reverberation time, clarity, etc. in octave and third octave bands), check if that room is well suited for its purpose and, if not, choose which materials can improve the acoustical quality. Everything still there but with an exciting improvement: now you can use all the power of the Exponential Sine Sweep technique for the measurement process, so your results can be extremely precise and accurate. You can also, save, load and export results in common spreadsheet format. The app can also generate pdf reports with photos. A tutorial slideshow explains the app use. Required at least iOS 11.0

Choose a target note and save a take that summarizes accepted pitch samples, while making weak, off-target or missing input visible. HOW IT WORKS 1. Open Intonation Takes in the Practice Lab and choose the note, concert pitch and tolerance. 2. Start a take with microphone permission. The app accepts only fresh samples that meet its input and target checks. 3. Stop and save the take, then review the median cents, accepted-sample percentage and rejected-sample count. The chromatic tuner, metronome and other practice tools remain available. WHAT TO KNOW A summary needs at least ten accepted samples. Percentages describe overlapping accepted samples, not time spent in tune. The app does not score silence as success. Device microphones, environment and instrument affect results; no calibration or real-room accuracy guarantee is made. iPhone and iPad.
