Build minor, major, dominant, or composite blues scales in any key with note spelling, interval formula, blue-note focus, chord fit, and fretboard position output. Blues Scale Presets Preset use: Load ...

Build either whole-tone collection from any root, choose practical spelling, inspect the six-note formula, compare the complement, and map augmented chord colors for composing, arranging, and practice ...

Convert acoustic sound power level, Lw, into estimated sound pressure level, Lp, at a listener or measurement point using distance loss, directivity, boundary radiation, room support, and air ...

Estimate how much to raise, lower, shim, or file a guitar saddle by combining scale length, 12th-fret action, neck relief, nut clearance, and intonation compensation. Common electric scale: 647.7 mm / ...

Check subwoofer impedance, RMS power match, amplifier stability, cable loss, current draw, and damping factor before pairing a sub with an amp. Count physical drivers connected to the amplifier ...

Formula set: speed = 331.3 + 0.606 x temp, wavelength = speed / Hz, ideal spacing = wavelength x layout factor, delay = spacing / speed x 1000, footprint = active shape area x buffer. Calculate Array ...

Air speed changes with temperature and humidity. Air temperature (C) Used only when the medium is air.

Size exponential horn flare from throat, mouth, length, temperature, and target cutoff.

Size speaker power, coverage, and speaker count for venues, then estimate the far-row SPL for speech, music, or live bands.

Estimate SPL drop from distance, air, path angle, and barrier loss for mics, monitors, live rooms, and stage sources. Use the same reference distance that was used to measure or estimate the source ...

Tip — Mono vs Stereo: For voice-only recordings (meetings, lectures, dictation), use Mono. It cuts file size in half with no quality loss for speech. Switch to Stereo only when spatial audio matters, ...

Tip 1 – Always Use Specialists: Grand pianos require leg and pedal lyre removal before transport. This must be done by experienced piano technicians — never general movers — to avoid damaging the ...
