Ratings and Reviews
Spectro:Skop is Awesome!
I've always had an interest in sound but I bought the app to help analyze a noisy piece of hardware at work. Even using the iPad 2 internal microphone I am extremely impressed with this app. There are enough settings available to make this app truly versatile.
You can capture several audio spectrums making it easy to compare noise/sound under several conditions so you can compare and analyze the differences. You can take a screenshot or export the data in csv format.
I initially had some microphone problems and consulted the developer. I got an immediate email response and the excellent support continued including several additional emails and a video (made for me) to show me what the display should look like. The support of the developer was very much appreciated. Excellent customer support.
This app has a lot to offer both the professional and the novice interested in learning more about sound frequencies and amplitudes. I highly recommend it.
Works well for measuring sound spectra in octave & 1/3 octave bands. Surprisingly accurate... dB(A) and dB(C) values measure within 2 dB of a calibrated type 2 sound level meter at frequencies between 400 Hz and 2 kHz (all bands that I tested), at levels of ~65 dB. Pricey, though less expensive than other options in the app store... and WAY less expensive than a standalone spectrum analyzer. The output .csv feature is quite useful. The developer could improve this function by adding the ability to view/rename/delete files outside of Itunes. Overall a solid app worth the $$$.
This has been a helpful and easy to use tool. It makes you wonder why the hardware gear is so expensive. All of them simply get you in the general ballpark then your ears do the rest. I don't believe that getting this app will be a regret if it saves your mix or ears just once. Just my humble opinion.
