Excellent RTA for the price

I love this can be on my phone, my IPad and laptop. For the cost, you won’t beat it. I even connect a small mic to my iPad. Don’t hesitate, get this RTA!

A properly-made Analyser or RTA. No weird subscriptions.

Firstly, this is a proper app, not trying to get subs or doing weird stuff. I am interested in the sonic environment, to help with music making, and although this does not do as a plug-in for eg garageband, it does work using either external microphones or the in-built mic. You can pinpoint a particular select band of frequencies and with that see the exact Hz and octave note and cent. That is useful.

Having bought the ipad app, i was able to download the iphone one using the cloud symbol on my SE, for no additional cost. Works in landscape orientation, and you will discover the panoply of background noise in your home and world!

I think this is a good app, and does the fundamental job well, and covers from zilch Hz, way up to 20kHz or so. eg i just did a point on the iphone, and it says 16000Hz telling me that is B9 plus 21.3c. ie ‘B’ note of the 9th octave, and a fraction more.

ASIDE:
Funny info, for any sticklers for musical or acoustic perfection...you know the entire western octave system is scientifically speaking, mistakenly created? Eg B1 may well not harmonise with B9. They made an error back when, not having accurate measuring of frequencies, and set the entire thing up being out by a fraction of a Hz every few notes...! Come on, that’s funny. [EDIT There is this factor to consider, but also if you research eg well known online encyclopedia, you find even when it’s all accurately done, the 12-note western octave system, still has anomalies, because it involves sqr root of 2, which as we all know, is 1.44 repeater. So when I made my synth output C1 and C7 or C8 at the same time, there was a discord, and that discord is inherent it seems, to the way the frequencies have to be split to form the western system. Indeed, compromises all over the place, no matter what system is used it seems. Under a few cents of difference or ‘wrongness’ seems hard to hear for most people, and yet I have read somewhere that a ‘correct’ tuning system was devised, but allegedly people did not take to the results, having gotten used to the flawed tuning now used. UPSHOT...tuning is a much bigger subject than a few maths gurus having rounding errors in their tables, and I am not qualified to give advice on it!]

Absolutely the #1 choice for all mastering engineers!

I bought 3 other apps before I found this one and wish I found this one first.. This app is solid and very accurate, I'm very happy!

Программа

Программа со своими задачами справляется, нету авто поиска торчащих чистот. А так удобна и практична.

Useful

Such a useful app, I use it all the time when doing an FOH EQ for live gigs. It's been invaluable!
