Product Details

True Audio TrueRTA Audio Spectrum Analyzer Software

True Audio’s Level Two (1/3 per octave) TrueRTA™ is a real-time software-based audio instrument for testing and evaluating audio systems using a PC with basic sound capability. TrueRTA™ also includes a digital voltmeter that reads true rms voltage and dBu levels, and an audio spectrum analyzer. To set up your own audio test lab you will need a digital voltmeter to calibrate TrueRTA™ for your sound card and a collection of cables and adapters for connecting electronic gear to your sound card for testing. Most sound card jacks are 1/8 inch. If you want to do acoustic testing of loudspeakers in addition to the above you will need a calibrated microphone (True Audio recommends the Dayton Audio EMM-6), a microphone preamplifier or mixer, an audio power amplifier to drive the speaker under test, and cables to connect the line-out of the sound card to the input of the audio power amp. Software can be upgraded to Level Three (1/6th octave) or Level Four (1/24th octave). Minimum System Requirements: 500MHz Pentium III processor and 64MB of RAM

True Audio TrueRTA Audio Spectrum Analyzer Software
True Audio TrueRTA Audio Spectrum Analyzer Software is rated 4.2857 out of 5 by 7.
Rated 5 out of 5 by from Wonderful value for the tech who knows how to use it.I've used many hardware and software analysis tools over my 40+ years as a tech, engineer, environmental noise consultant, and teacher. Most, i.e. SMAART, are very expensive, especially for a retired guy on a fixed income. This is such a wonderful tool. Perfect for my current projects. Hat's off to John Murphy, and PE for making this widely available.

Rated 4 out of 5 by from Functional software you need, works well, interface is datedI was so excited to get this and use it with the Dayton condenser mic (also purchased here) to test out a new subwoofer and its placement in my home theater. You'll need the mic, a usb mic interface, and this software, and for about 1/3 the price of a basic component RTA, you have a professional tool.This software works, and most likely has worked for a long time based on the dusty interface. . . small buttons, no mouse over/contextual help, etc. I hate having to resort to the manual for software nowadays since you can typically learn while using the product. But the manual is well written, informative, and helps with the sea of tiny buttons. Even if it was written in the Pentium 4 days.Interface aside, it allows you to calibrate and compensate for all of your hardware as well, down to the output voltage and inherent frequency response curve of your sound card, and in simple easy steps.So, what my experience tells me is that they haven't changed anything because it just works. So overall, maybe that isn't that bad.

Rated 4 out of 5 by from Great - Averages Multiple Measurements for a Room!This software gave me the ability to take multiple measurements throughout a room. I wanted to be able to average these multiple measurements and this software will do that. I can finally get the average system response for an entire room. The upgraded software at 1/24th octave resolution is awesome for seeing how standing waves, peaks, dips, etc. change throughout a room. It is great to be able to have the Pre-EQ and Post-EQ averaged responses just a click away from each other. That way I know how accurate my attempted improvements were. A picture is worth a thousand words when showing a customer what they are hearing throughout an entire room (1/12th octave resolution is my favorite for this. Sometimes I find that different locations in the same room will have completely opposite bass responses graphs.) I've decided EQ'ing an entire system based on one measurement is not wise (especially below 200 hz. I use this software to see the response of a system at the mix position and compare it to what the audience will hear. I've used this while designing speakers, testing the frequency response of an EQ or Microphone Preamp as well as generate test tones at any frequency I want. The sound system calibration is a great feature that allows you to know your computer is not adding its own color to your measurements. I like that it has shortcuts for the commands I use most. It is not a flashy program, but it gets the job done. I have not used other software that allows users to average multiple measurements, but I've not seen another for $40. I have upgraded to level 4 and love it. I've been using this software for 3-4 years.I'm sorry Mac only Users will not be able to use this software unless that has changed recently.

Rated 4 out of 5 by from Works great, easy to use, glad I bought it.Only complaint is the cost to upgrade from 1/3 octave to higher frequency resolution levels (1/6 octave, etc.) The minor added complexity in the code does not justify the high surcharge. I would upgrade for a small service charge, but not for double the original price.

Rated 4 out of 5 by from Excellent Laptop computer toolFor remote testing of audio products, you simply cannot beat this product. This is a must have item.

Rated 4 out of 5 by from Excellent valueThis program has several limitations: auto sweep is not available, SA resolution is low, trigger functionality is very limited. The first two features are available in more expensive versions. I hope they eventually provide trigger level, single sweep, delayed sweep, and lock to generator functions in the full-featured version. However, there is still enough capability to be very useful to the hobbyist. For example, you can do frequency plots fairly easily by manually stepping the frequency and enabling peak hold. Also, all features that are available worked perfectly. So it is an excellent value for the price.

How does the True Audio RTA compair to the Dayton Omni Mic system.

This question was asked before and the True Audio RTA was compaired to the Goldline RTA not the Omni mic.
Asked by: Kelly383
Looks to me the software does pretty similar things, although details differ.To me the hardware requirements/configurations are quite different. The Dayton system provides a USB mic, but that means you are limited to the max length of a USB cable (which is I think about 15 ft) to the computer. This can be a big drawback if you need to remotely locate the mic from the PC. Each mic has its own cal file which can be downloaded and entered into the software which is nice.The Dayton system also relies on the playback of specifically formulated files from a CDROM through the sound system. A problem if you don't have a CD playback device. You can rip files from the CD to the computer and play them back through the soundcard but this could create cal problems for precise measurements.The True Audio system requires the purchase of outboard USB pre-amps and a calibrated mic. It is unclear whether the cal files for the Dayton mics, for example, can be entered into the software like they can with the Dayton system. The signal sources like pink noise, sine wave, etc are supplied by the software but need to be played though the soundcard, which requires calibration. They can also be output to a USB preamp which may be preffered as it bypasses the sound card (but adds cost to the system#.And finally, PE only sells the basic 1/3 octave version. If you want higher precision, you need to pay up to about $100 for the advanced version. If you look at a good quality outboard preamp, XLR mic cable, a Dayton EMM-6 mic, and the premium upgraded software, you are looking at about the same cost as the Dayton system #@ about $300). You also have to buy interconnects to the sound system you are testing. But with this system you are not limited by a CD player and can run long mic cables from the mic to the pre-amp.The Dayton system, although less flexible, is faster to set up and use. Closer to plug and play and you don't need to mess with cal of or use of a computer sound card.

What's the difference between this and Dayton OmniMic?

I understand that OmniMic comes with a microphone, but on the software side, do the programs do the same thing? I am building speakers and want to test their performance. What will I need? Thanks.
Asked by: Mulluysavage
The difference between the Dayton Omnimic and the Gold Line DSP-30 Portable Digital RTA is that the Gold Line DSP-30 is a self contained and highly accurate piece of test equipment that when used in conjunction with an accurate calibrated mic and pink noise generator will yield true pro audio measurements and accuracy.The Dayton Omnimic is a good piece of equipment and software that can and is affected by the laptop's sound card and interconnection cables.The included mic is a little lower in quality than the $99.00 DBX cal. mic. Combining these items do not provide the accuracy possible from the Gold Line DSP-30 Portable Digital RTA. It pretty much depends on your need for true accuracy from a real time analyzer.Good Luck

Mic calibration

I would like to know if this software uses the mic calibration files for Dayton EMM-6 mics to compensate for FR errors? I could not find anything on this on the True Audio website or FAQs, execpt for a comment that if the individual mic is not calibrated, then don't use a file at all. This makes no sense to me.
Asked by: DHL1
Plug all into ypur tape in/out on your receiver, then plug-in 'aux' your Computer, go to you-boob, and listen to some Black Rebel Motorcycle Club 100- 110 videos, and you'll ge the sound you want.... Make sure your mic. is a dual....You probably have a 'hum', not "dead-silent", and THAT will misconstrue A LOT of things in this sense. Try a Power Module w/ an isolator, or turn-off ALL fans as well as flourescent lighting, and even 'dimmers'.... I've had to do ALL of that o get the 'hum' out of the system as is...

How do I copy onto my new computer-I lost the original disc

I really enjoy this product. The Real Time Analyzer software's oscilloscope feature is a bonus as well as it's spectrum analyzer capability. My problem is that I just got a new computer and I want to transfer the program from my old laptop to my new laptop. Any help would be appreciated. Thanks
Asked by: Charlie G.
I think you will need PE tech help for this. It isn't copying, it is also installation.
