APM Sweep vs RIP DJ

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

RIP DJ is a spectrogram tool for DJs. Drop in any track — MP3, FLAC, WAV, AAC, M4A, OGG, Opus — and RIP DJ analyzes its full spectrum on your device. A live spectrogram and waveform appear while the track plays, and a full-track spectrogram renders once the scan completes. Share the spectrogram image with track metadata to any app. The FFT runs entirely on your phone. No uploads, no accounts, no analytics. Files you analyze never leave the device. The app makes no network requests at all. https://www.ripdj.com/privacy https://www.ripdj.com/terms
