It's basically very flat even without any corrections, but here is a correction file for it too.
Much better choice is a Behringer ECM8000 microphone and a Behringer UB802 preamp/phamtom power. The digital version does not need any corrections when connceted from the output jack. I personally have the older analog model, but the newer analog will work just fine. With the correction file it is reasonably accurate down to 15-16Hz. Frequency response of the RS meter limits up to around 10kHz (even with correction file). Save it as a text file along your other correction files (in "TrueRTA/Mic calibration files" folder). NOTE: Check the end of this post, more info about RS. You can download the correction file from here. You can find few compensation charts for it, but none of them is perfect for your meter. You can use the Radio Shack SPL meter as a microphone, but its accurancy is not very good. For example M-Audio MobilePre USB is great. Use a USB or PCMCIA soundcards with laptops. I haven't yet seen a laptop with a decent soundcard. Integrated soundcards like nVIDIA Soundstorm will work, but they are more difficult to calibrate, you need to set the input/output levels very carefully with them. If you have some expensive soundcard, it will most probably work. Soundcard must have line in and line-out connections. Most modern soundcards will work just fine, for example almost any Soundblaster (Live, Audigy, Aydigy2 etc.) is fine. Computer/laptop equipped with a decent soundcard.Ī 500 MHz Pentium III class PC with 64MB RAM running The program itself is very small (~1.4MB installed), but the project files are around 10MB each, so make sure you have atleast that much of free space on that drive. Here is a little proof why 1/24 is recommended.īefore anything, read the help files/topics, they are very helpful. If you absolutely can't make it, take level 3, it comes with 1/6 octave resolution. Level 4 retails $99.95, but it's all worth it.

I definitely recommend level 4, because this way you get the full 1/24 octave resolution, which is almost a MUST, especially if you are planning to some EQ'ing with BFD or similar.
#Truerta free upgrade
True Audio offers four different upgrade levels from 1 to 4. To make the most of it, you need to purchase an upgrade. Unfortunately the demo is quite limited so you can't really use it efficiently. The free demo of the program can be downloaded from here. TrueRTA is a nice and small RTA-program (Real Time Analyzer) made by John Murphy. Since HTSpot transferred this quide into section where you have to be a paid member to get in, I decided to copy it here.
