Downloadable Software Program Is Better Than Buying A Refurbish

By: Low Jeremy

There was a time that the analysis of spectral composition whether it is an electrical, acoustic or optical waveform was done using a large machine similar to those used in a recording studio.

These days, computers and other machines can do the same by simply downloading the software. Here a few examples of those readily available.

1. If the person at home is using either Windows2000 or XP, the program called Spectrogram 14 can offer a spectrum analyzer scope display in real time for any source that is connected to the sound card.

This in turn allows the user to download songs so this can be played back later on with clarity for easy listening. The software can also be used to analyze biological and bat echolocation sounds as well as the identification of human speech.

2. An older program that can also be downloaded is the DL4YHF Audio Spectrum Analyzer. This was already out in the market even before windows came out using the DOS system. To be able to keep up with the times, a digital version was launched.

This is better known these days as a specialized audio analyzer that can act as a data logger, filer and a frequency converter.

3. The OscilloMeter also known as Spectrum Analyzer 4.14 is another good choice. It comes with a frequency counter, noise and distortion meter, phase shift meter and a voltmeter. The only catch is that this has to be bought for $399.

4. The SpectraScope is something that will be very useful for the professional audio engineer or someone who is just a hi-fi enthusiast. The individual can listen to four different sounds simultaneously or separately for easy comparison.

It supports all Windows Operating systems and this can be downloaded for a free trial for just $30. People who like what it can do can buy the program later on.

5. TrueTRA, a company based in Tennessee has a similar program that is not that expensive. For less than $40, the person can buy the program and then use it to analyze sounds using the different meters it has.

Most of the downloadable spectrum analyzers are free. It doesn't occupy a lot of space in the hard drive for this to work. The only thing needed is an Internet connection so this can be installed in a few minutes and the person can begin to use it.

Scientists and engineers need a spectrum analyzer in order to study wavelengths. These machines are expensive and if the person doesn't have one, the best thing to do will be to a refurbished unit that is much cheaper. The individual may find one in the junk shop and then replace the old parts with those that can be bought in Radio Shack. However, there is another way to do such studies without spending so much on equipment.

The person can do this by downloading the software in the computer. If the engineer has a laptop or a desktop at home and is using a Windows as an operating system, a program that will work is the Spectrogram 14 that has a heads up display showing everything in the monitor. This can be used to analyze video and audio files that are stored in the computer's hard drive. An amateur video director can even use this to edit the film before showing the final product.

Another good choice is the Oscillometer that is known by some as the Spectrum Analyzer 4.14. It has other things that appear on the display, which is why it will cost a little over $400, but this will still be cheaper than getting a brand new spectrum analyzer that could occupy a lot of space in the office.

Sometimes, the sound engineer has to bring some work home. Another program that can be downloaded into the computer is the Spectra Scope, which allows the user to listen to up to four tracks simultaneously or one by one. For those that are skeptic about what this program can do, the individual can sign up for a free trial for just $30 and if happy, the customer can purchase the entire package later on.

People who can't afford to spend something above a hundred dollars and are unsure if something free can work can try the TrueTRA that can be bought for less than $40. It also has the different meters to analyze wavelengths just like the others.

Buying a refurbished spectrum analyzer is like buying a second hand car that has to be put together for it to be up and running again. The individual may not have the time to get the parts one by one so downloading this for free or buying a copy of the program at an affordable price seems to be the better option to get the job done.
