Analyze a chord progression by key, Roman numerals, harmonic function, transposition, and cadence clues.

Math & Numbers

Design a normal-weight concrete mix per ACI 211.1-91 absolute-volume method. Inputs: slump, nominal max aggregate size, air entrainment, water-cement ratio w/c, fineness modulus of sand, and dry-rodded coarse-aggregate density. Outputs the per-cubic-meter masses of cement, water, fine and coarse aggregate plus the mass ratio.

Media

Clarify listening audio with low-frequency cleanup, speech-presence EQ, conservative denoising, and level protection.

Media

Mix an audio-description narration into program audio while ducking the program when narration is present.

Math & Numbers

Calculate the basic rating life of a rolling bearing: L10 = (C/P)^p, with p = 3 for ball bearings and p = 10/3 for roller bearings. When a speed is provided, converts to L10h in operating hours.

Math & 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.

Media

Find likely simultaneous speech-like activity by detecting multiple balanced voice-frequency bands.

Media

Mark likely acoustic turn changes in speech-range audio and export an approximate turn timeline.

Math & Numbers

Calculate the ratio, driven speed and belt linear speed of a belt drive. i = d₂/d₁ = n₁/n₂, belt speed v = π·d·n/60. Supports mm/cm/m/inch diameter units.

Math & 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.

Math & Numbers

Calculate the ratio, driven speed and chain linear speed of a chain drive. i = z₂/z₁ = n₁/n₂, chain speed v = z₁·p·n₁/60000. Enter the pitch to compute chain speed.

Media

Split a long sermon or lecture at reliable silences and optional timestamped topic, applause, or music hints.
