SignalScope Pro

With Faber’s move to the greed of a subscription model, I’ve come to the end of the road with them. I just can’t justify providing any tacit support to a model that I just don’t believe in.<br/><br/>Faber has chosen this path. However, I too have choices. And as a casual, non-professional user of their product, I will choose other options when my version of Signal Scope meets its demise.<br/><br/>It was nice while it lasted. Fare thee well Faber.

SignalScope Pro for iPhone includes the essential meters every sound tech and contractor needs for daily work. Input can come from the built in microphone, or an external mic. SignalScope Pro can also use the iPhone's built-in accelerometer to analyze vibrations. The FFT and Octave-band analyzers are easily configured, and by tapping the screen, you can easily see peak frequencies and harmonics.<br/><br/>With the improved frequency response of iOS 6, the analyzers and sound level meter are now plenty accurate across the audible range. The default sensitivity of the SignalScope was within a dB or two of a calibrated sound level meter, which is plenty good for most situations. I have not had a chance to compare the spectrum displays to my standard rig, but it looks to be in the ballpark out to 10 kHz or so. If you want a better microphone, there are options available, but the built-in mics. aren't half bad. My only complaint with the SLM is that the slow response is too fast, but it's a minor niggle.<br/><br/>SignalScope Pro has many more features, including a signal generator and oscilloscope. These require additional cables and clutter, which, for me, negates the best feature of all: Portability. While SignalScope Pro will not replace my laptop-based rig, the ability to have your essential meters available anywhere, anytime, opens a world of possibilities. <br/><br/>If you have an iPhone, are serious about sound, and wondering where best to spend the next $74, you really need to consider this app. It's a game changer.

This is a tool, not a toy. Yeah it's not $0.99, but it's solid and accurate.

This was a great but expensive tool. It was discontinued in January 2018 for a $72/year subscription product (Signal Scope X). This version is no longer updated as of March 2018.

It does everything computer based high end programs can do but does it on the iPhone. Lacking right now (but supposedly in development) is a way to get your analytical mic connected to your iPhone 4. What we need is a phantom supply/dock connector with A-D capabilities. You cannot use the 3.5mm jack as it has a curve to it (iOS built in) that prevents accurate, flat and extended response capabilities.<br/><br/>When this is worked out I will no longer have to cart around my computer for true, accurate audio analysis.

Our products require acoustic testing. Since this app has the potential to become something our customers might use, we figured we better buy it and compare its results against our B&amp;K meter. The built in iPhone mic works pretty good, and I am impressed with this app. I can even see situations where I might use it instead of the B&amp;K. I really don't like what it takes to see some of the data though. Being able to email the .txt file to yourself would be more flexible and useful than the HTTP server. If Faber wold change that, I would give it five stars.

At first I was sceptical but once I tried it out and compared it to my other anylizer (phonic), I was very impressed. The signal generator is great for quick setups and there's no more packing around a clunky anylizer. Just pull your phone out of your pocket and go! It may not be PERFECT with the built in mic but it's pretty frik'n close! If you do a lot of sound setup, BUY IT.

I guess I should have looked a little more closely at the frequency response specs for the iPhone 4 but in my defense the iPhone 4 was not even addressed on this apps web site. At the time of my purchase. The problem is that the iPhone 4 uses a high pass filter ( or a shelf ) around 100 HZ on both the internal mic and the headset mic line thus making accurate readings below 100HZ impossible. I was later able to confirm this in a &quot;forum&quot; but I think that info should have been made readily available on their web site info. This is a big deal to me as we use SUBS all the time. At this time I'm unaware of any workaround for this issue. It's a shame because this is such an incredible tool otherwise but it's like a prizefighter with one hand tied behind his back until this issue can be addressed.
