Media
Turn speech phrases into a repeatable practice track with a configurable pause between repetitions.
audio-language-learning-loop-makerMedia
Level a mixed meeting recording, reduce low rumble and keyboard-like clicks, and produce a meeting-ready audio file.
audio-meeting-recording-normalizerMedia
Clarify listening audio with low-frequency cleanup, speech-presence EQ, conservative denoising, and level protection.
audio-assistive-listening-enhancerMedia
Mix an audio-description narration into program audio while ducking the program when narration is present.
audio-audio-description-duckingMedia
Shift SRT or WebVTT captions to a likely speech onset or by a manual offset.
audio-caption-timing-shifterMath & Numbers
Calculate the follower displacement, velocity coefficient, acceleration coefficient and pressure angle during the cam rise phase. Supports constant-velocity, constant-acceleration, harmonic (SHM) and cycloidal motion laws.
cam-follower-displacementMath & Numbers
Calculate the critical (resonance) speed of a rotating shaft using the single-DOF rotor model. ω_n = √(k/m), n_cr = (60/2π)·√(k/m) rpm. Also returns the natural frequency f_n in Hz.
shaft-critical-speedMedia
Compare SRT or WebVTT cue timing with likely speech activity and flag timing drift.
audio-caption-sync-checkerMedia
Find likely simultaneous speech-like activity by detecting multiple balanced voice-frequency bands.
audio-overlap-speech-detectorMedia
Mark likely acoustic turn changes in speech-range audio and export an approximate turn timeline.
audio-speaker-turn-detectorMath & Numbers
Convert between bolt tightening torque and axial clamp force. T = K·F·d, where K is the nut factor (~0.20 for dry steel). Solve torque from force, or force from torque.
bolt-torque-clamp-forceMath & Numbers
Calculate the power transmitted by a rotating shaft. P = T·ω = 2π·n·T/60. Solve power from torque and speed, or torque from power and speed. Supports W/kW/hp.
