CreamAudio Analyzer vs Resistor Code Calculator Pro

CreamAudio turns your Mac, iPad, or iPhone plus a class-compliant USB or Thunderbolt audio interface (such as a Focusrite Scarlett 2i2) into a complete professional audio measurement bench. The interface's analog inputs become the front end; its outputs drive the built-in signal generator. Multiple precision instruments share one calibrated signal path: OSCILLOSCOPE • Live two-channel display in normal (Y-t) and XY (Lissajous) modes • Adjustable volts/division and time/division with pinch and scroll zoom • Edge triggering with Auto / Normal / Single modes and single-shot capture • Graticule with division labels and live Vpp, RMS, frequency readouts • Per-channel DC/AC coupling and vertical offset FUNCTION GENERATOR • Sine, square, triangle, sawtooth, white and pink noise • Per-channel frequency, amplitude, offset, phase, and duty cycle • Sweep, chirp, and burst programs • Test Tape: an automated alignment-tape sequence (reference tones 400 Hz to 12.5 kHz, sweep, chirp, burst, flutter tone) to record onto a deck and measure back • Route to the same interface (loopback) or a separate output device SPECTRUM & SPECTROGRAM • Real-time FFT spectrum with selectable size and windowing, log/linear axes • Spectrogram heatmap across the recorded timeline FREQUENCY RESPONSE • Measure response with white / pink / swept stimulus that drives the generator automatically; curves accumulate for easy comparison DISTORTION & LEVEL • Automatic THD, THD+N, and SNR measurement • Vpp, Vrms, mean, frequency, period, and duty-cycle readouts • Built-in analog-style AC millivoltmeter (1 mV to 30 V, dual volt/dB scales) WOW & FLUTTER METER • Speed-stability analysis for turntables, cassette, and reel-to-reel tape • DIN / IEC 386 (3150 Hz) and JIS (3000 Hz) reference tones with auto-detect • WRMS, DIN 2-sigma quasi-peak, and unweighted readings; deviation waveform RECORD, SCRUB & EXPORT • Record the raw two-channel stream and scrub the timeline to find transients • Re-run any analysis offline on a selected window • Save recordings to WAV (lossless) or AAC (.m4a) CALIBRATION • Map normalized samples to real volts with manual entry or a guided reference solve, so every reading is in true voltage units; profiles persist per device Sample rates up to 192 kHz where the interface supports them. Everything runs locally on your device — no account, no network, no data collection. Requires a Metal-capable device. An external audio interface is recommended for real measurement work; the built-in microphone can be used for casual signals. Requires a subscription or one-time purchase. Start with a 3-day free trial, after which a monthly subscription begins automatically and renews each month unless cancelled at least 24 hours before the period ends. Prefer to pay once? Unlock everything with a one-time lifetime purchase — no trial, no subscription. The free trial is available to new subscribers. Subscription and lifetime prices are shown in the app and on this product page. All features described below are included once unlocked; there is no separately-priced content.

Resistor Calculator is a practical offline toolbox for electronics students, makers, repair technicians, and engineers who work with resistors and common circuit calculations. Decode resistor color bands, convert resistance values into color bands, read SMD resistor markings, browse E-Series values, and solve everyday resistor-related circuit problems in one focused app. RESISTOR TOOLS • Decode 3, 4, 5, and 6-band resistors • Convert resistance values into color bands • Support engineering notation such as 4.7k, 4k7, 2M2, and 0R22 • Calculate tolerance, minimum, and maximum resistance • Show temperature coefficient for 6-band resistors • Reverse resistor reading direction • Copy, share, save, and reset results SMD RESISTOR CODES • Decode 3-digit and 4-digit SMD codes • Support R, K, and M notation • Support EIA-96 markings • Handle zero-ohm resistors • Convert resistance values back into suitable SMD codes • Explain decoded values clearly E-SERIES VALUES • Browse E6, E12, E24, E48, E96, and E192 values • Find the nearest standard resistor values • Compare error and tolerance ranges • Open selected values directly in resistor tools CIRCUIT CALCULATORS • Series and parallel resistance • Ohm’s Law • Voltage divider • LED current-limiting resistor • Target resistance combinations • Wheatstone bridge • Op-amp gain • Star / Delta conversion • Wire resistance • Voltage drop • Pull-up / Pull-down resistor • RC time constant LIBRARY WORKFLOW • Save calculation history • Add results to Favorites • Organize values and calculations into Projects • Export project data as CSV, JSON, or plain text • Review saved calculations later BUILT FOR DAILY ELECTRONICS WORK Resistor Calculator is designed to be fast, clear, and focused. Results update immediately as you enter values, and formulas are available when you need to understand how a calculation was made. All core calculations run on your device and the app works without an account or internet connection.
