iChromatic Strobe Tuner HD vs RT60 Uso & Estadísticas

12 Simultaneous Visual Strobe Tuners for any musical instrument, fast, accurate, and noise resistant, using the built-in mic on your iPad. The multiple unique high contrast waterfall strobe visuals will quickly display the tuning in any of 12 note pitches and harmonics simultaneously. With 12 simultaneous strobe tuners, you don't need to wait for your room or recording studio to become quiet enough. You don't need to wait for a tuner to lock onto each note. You don't need to wait for a needle to finish moving. If you're really good, you don't even need to tune one note at a time. With multiple strobe tuners, you can see if one pitch shifts in frequency while tuning another. You can also see if plucking a string hard on a guitar causes the notes to "bend". Just watch the waterfall waveforms overlaid on each string. When the waves for a particular note synchronize or line up vertically, and stop leaning or shifting left (flat) or right (sharp), you are precisely in tune with an internal equally-tempered digital oscillator. If you are not sure if you understand using a waterfall strobe tuner, please download the Free inTuna A440 app from the App store (which can only tune 1 note: concert A = 440 Hz) and give it a try. For custom intonations, you can individually vary the reference frequency of each string in 1 cent increments up to +-30 cents away from equal temperament. The A440 reference is also adjustable. Notice: This app plays no piano sounds! It only allows you to visualize pitch from the microphone input.

RT60

Now you can have an RT60 measurement tool for the iPhone. Another in the series of acoustic analysis and test applications from Studio Six Digital, RT60 measures reverb decay time for each octave band, 63Hz - 4kHz, by pulsing pink noise on and off, filtering the incoming signal by octave band, and measuring the timing of the decay of each octave band. RT60 conforms to international acoustics standard ISO 3382 for measuring room decay time (RT) using either the T20 or T30 method. RT60 will measure down to 50ms, and up to 4 seconds. Results are displayed for each band above the band, and the overall RT60 is calculated and displayed on the top of the screen. RT60 requires at least 25dB of headroom between the noise floor of the environment, and the level of the pink noise for T20 analysis. Turn up the amplifier to get more headroom. To use RT60, connect the iPhone output to the input of an amp and speaker, and carefully turn up the level after you tap the Generator icon. RT60 smoothes the results of several readings to get a more stable result. *** Screen Graphics The red bars are the current SPL level for each octave band. The thin black bars show the most recently measured maximum and minimum dB levels for the octave band that the RT60 calculation is using. The vertical yellow bars show the decay range that is available. Note that in some situations, you may not be able to overcome the ambient noise level in the room to get a good reading in every band. *** Calculations If a valid RT60 time can be computed, it is shown above the yellow bar. If it cannot be computed, no bar or value is shown. When your analysis is complete, you can save the graph image to your photo roll to include in a report. *** Calibration & Microphone Like all of the Studio Six Digital apps, RT60 can be calibrated. We set this field to the typical iPhone value, but if you have access to a calibrated SPL meter you can adjust this number as needed. There is a field to select Internal or External microphone. When Internal is selected, a compensation network is used to compensate for the response of the built-in or headset mic. When External is selected, no compensation is done.
