Tension Meter Companion vs Simple Spectrogram

The BRECOflex Tension Calculator is a companion application designed to be used with the BRECOflex tension meter. It allows users to calculate belt tension and frequency accurately based on measurement data from the device. The app is intended for technicians, engineers, and maintenance personnel who require reliable and repeatable belt tension calculations in industrial environments. By simplifying the calculation process, the app helps ensure proper belt setup, improved system performance, and extended belt service life.

See the frequencies in the sound around you. Spectrogram turns your microphone input into a smooth, real-time spectrogram with a clear logarithmic frequency scale and Inferno colors. • Watch sound evolve over time, with the newest audio at the top. • Pause and tap any slice to inspect its frequency spectrum. • Tap or drag on the spectrum to find nearby peaks and their exact frequencies. • See the nearest musical note and the difference in hertz and cents, referenced to A4 = 440 Hz. • Adjust the frequency range, noise floor, and contrast. • Use portrait or landscape on iPhone and iPad. Audio is analyzed on your device in memory. It is never recorded, uploaded, or shared. No account, ads, or tracking. Musical note labels describe individual spectral peaks, which may be harmonics rather than a sound’s fundamental frequency.
