If you are looking for a powerful and versatile audio spectrum analyzer software, you might want to check out TrueRTA Level 4. TrueRTA is a software that turns your PC into a real-time audio analyzer, allowing you to measure and analyze the frequency response of any audio system. TrueRTA Level 4 is the highest level of performance offered by TrueRTA, and it provides the finest resolution and accuracy for audio analysis.


What is TrueRTA Level 4?




TrueRTA Level 4 is a software that runs on Windows operating systems and uses the sound card of your PC as the input and output device. TrueRTA Level 4 can measure the frequency response of any audio system, such as speakers, headphones, microphones, amplifiers, equalizers, filters, mixers, etc. TrueRTA Level 4 can also generate various types of test signals, such as sine waves, pink noise, white noise, impulse waves, etc., to stimulate the audio system and measure its response.

TrueRTA Level 4 has several features that make it stand out from other audio spectrum analyzer software. Some of these features are:



  • It has a fully adjustable frequency scale from 10 Hz to 50 kHz, which covers the entire audible range and beyond.



  • It has a fully adjustable dB scale from +20 dBu to -160 dBu, which allows you to measure very loud or very quiet signals.



  • It has an adjustable dB SPL scale from +180 dB SPL to 0 dB SPL, which allows you to measure sound pressure levels in different environments.



  • It has a real-time analyzer (RTA) that can display the frequency spectrum of any audio signal in different resolutions, from 1 octave to 1/24 octave. The higher the resolution, the more detail you can see in the spectrum.



  • It has a signal generator that can produce various types of test signals, such as sine waves, pink noise, white noise, impulse waves, etc., to stimulate the audio system and measure its response.



  • It has an oscilloscope that can display the waveform of any audio signal in dual trace mode. You can also freeze the display and take measurements with a cursor.



  • It has a digital multi-meter that can measure the voltage (RMS or peak), dBu (RMS or peak), crest factor (in mV/mV or dB), and SPL of any audio signal.



  • It has a calibration feature that allows you to calibrate the line-in and line-out levels of your sound card, as well as the SPL meter and microphone. You can also use relative mode to compare different measurements.



  • It has a data import and export feature that allows you to save and load data in various formats, such as WAV, TXT, CSV, etc. You can also print detailed reports in color or black and white.



  • It has a project file feature that allows you to save all the data and notes for each measurement in one file. You can also overlay up to 20 memories on the RTA display for comparison.



  • It has a data utility feature that allows you to perform various operations on the data, such as average, smooth, shift, sum, and difference. You can also add automatic or manual notes to each measurement.




How to use TrueRTA Level 4?




To use TrueRTA Level 4, you need a PC with Windows operating system and a sound card with line-in and line-out ports. You also need a microphone and an SPL meter if you want to measure sound pressure levels. You can download TrueRTA Level 4 from [the official website] for $99.95. Once you download TrueRTA Level 4, you can experience the free level 1 sound analyzer with 1 octave resolution. If you want to upgrade to higher levels of resolution, you need to purchase a registration code from [the online catalog] and enter it in the user registration menu under the help menu.


To use TrueRTA Level 4 for audio analysis, you need to connect your audio system to your sound card using appropriate cables and adapters. For example, if you want to measure the frequency response of a speaker, you need to connect the speaker output to the line-in port of your sound card, and connect the signal generator output to the speaker input. You also need to place the microphone and the SPL meter near the speaker and connect them to the line-out port of your sound card. You can then calibrate the levels and SPL using the calibration menu under the tools menu.


Once you have set up your audio system and calibrated the levels and SPL, you can start the measurement by selecting the RTA mode under the view menu. You can choose the resolution you want from 1 octave to 1/24 octave. You can also adjust the frequency scale and dB scale using the sliders on the left and right sides of the display. You can then start the signal generator by selecting the signal type and frequency range under the tools menu. You can also adjust the signal level and duration using the sliders on the bottom of the display. You can then see the frequency spectrum of your audio system on the RTA display. You can also use the cursor to read out the data at any point on the spectrum.


You can save the data and notes for each measurement by selecting save project under the file menu. You can also load previous project files by selecting open project under the file menu. You can overlay up to 20 memories on the RTA display by selecting overlay memories under the view menu. You can also perform various operations on the data by selecting data utilities under the tools menu. You can export or import data in various formats by selecting export data or import data under the file menu. You can also print detailed reports in color or black and white by selecting print report under the file menu.
