A suite of useful tools and calculators when setting up a stereo. Includes:Tone generator- Sine, square, triangle, sawtooth waves and linear, cubic, exponential sweeps and white, pink, blue noise.Enclosure builder – Rectangular, wedge and circular enclosures, sealed or ported, calculates dimensions given the material thickness, volume and port specsEnclosure response graph- Determine the relative gain of the enclosure, based on the T/S specs of the subwoofer.Crossover builder- Gives values and schematics for crossovers given load and frequency (High, low, bandpass, narrow bandpass crossovers and Zobel filters).Wire Gauge Calculator – Automatically calculate length, load, gauge or number of runs by inputting 3 out of the 4. Also includes a list of wire specs for common gauges.Decibel Meter – Calculate the relative decibel level around the device.(PLEASE NOTE: This is limited by the hardware. The microphone is designed for capturing voices (300-3400Hz). Outside this range, the microphone is not as responsive.)Amplifier gains calculator- Given the rated specs of your amplifier, you can properly set your line output to eliminate any clipping.Ohm’s Law Calculator and Common Equations- Calculate Voltage, Amperage, Wattage or Resistance by inputting 2 of the 4. Includes most common equations for car audio (components in circuits, area and volume of shapes, enclosure specs, waves, etc)Resistor value finder- A visual tool to calculate the resistor value given the resistor bandLED resistor calculator- Find the correct resistor for an LED to run on any voltage circuitSpeaker wiring calculator- Find the final load of any series/parallel speaker circuit, given the voice coils and impedance. Wiring diagrams for most common setups.
