iOS apps for us, sound obsessives

I would like to recommend a few very useful iOS apps which helps me tremendously in many situations be it live or post production work. I assume I’m not the only one who use clever little apps in his workflow. In case you know some other, suggestions are always appreciated.

AudioTools

This is one of my very favourite one. It is a very serious tool with lots of options and possibilities. It is made by StudioSixDigital. There is a base app, and if you need more you can buy things inside the app through in-app purchase. SPL meter, acoustical analysis tools, speaker tests, generator, audio calculator and many more.

Obviously on its own, none of the iOS devices is good for serious measurements, but they are definitely good for some troubleshooting, and with some clever gadgets, they can indeed become more serious tools in our arsenal.

StudioSixDigital realised that these gadgets needs some help to really be helpful, so they decided to invent and manufacture some complementary device such as the new iTestMic. With this little microphone, you can perform quite serious measurements. Obviously it won’t outperform the most sophisticated instruments, but it is capable of doing very precise things.

The company ported the famous Smaart tools to iOS, and I have to tell you it is wonderful. Fast, reliable and very useable.

Live Toolkit

As the name suggests, it is more intended toward live sound applications. Made by Rockbaby, a very well thought out app which not only useful for sound guys, but for “light” guys too as it can show you the fixture sets, dmx address dip switch positions.

On the sound side, it provides a good converter for distance (meter-feet-ms-hertz), eq (bandwith-q), and weight (kg-lbs). The more sophisticated part is the ability to determine your limiter settings through speaker and amp parameters.

It is not an app packed with features, but still offer some very useful things, it’s fast and stable.

Backline calc

It is made by Audiofile Engineering, and as their reputation is high for a reason, this app won’t disappoint you either. One of my favourites actually as it is so useful.


What it does as a calculator:

length:

  • note length
  • bar length
  • song length
  • beats to tempo
  • time to samples
  • compare tempos
  • change tempo
  • sum times
  • subtract times

pitch:

  • note name to
  • midi note to
  • frequency to
  • wavelength to

timecode:

  • frames to timecode
  • convert timecode
  • change timecode

electric:

  • compare power
  • compare voltage

acoustics:

  • distance to time
  • time to distance
  • SPL
  • panning

files:

  • file size

In every function there are easily adjustable sliders, but with a double-tap, concrete values can be entered as well. The whole gui is very minimalist and very easy on the eye. If one thing I would like to be changed is to blend some calculation together, as sometimes it is harder to find the right calculator from the long list. But keep in mind that it is a free app!

RadioKit

Also made by Rockbaby, a very valuable app which helps to identify the safe frequencies for your wireless packs. Knows many devices, country regulations, you can define user groups, make different sets and save them for later reference.

I cannot count how many times I need an app like this during the summer festival season. Tuning the wireless sets to safe zones is very fast and easy with this little app. From this point on, you can check and/or retune your wireless mics or in-ear monitors after a few taps on your iPhone. It’s also comes very handy in theatre situations where we use many wireless equipment.

MusicMath

Today’s last app is also a very useful one in my opinion. MusicMath is a timecode calculator, a tap tempo utility, a length to delay to modulation calculator and a note-frequency-cents-midi calculator all in one little app. Made by Laurent Colson.

Touching the info (i) button anywhere in any calculator brings up the application’s help.

Every little built-in utility has some nice treat for the user. The timecode part has a history function, the tap tempo utility has a rounding function which can be handy, the delay part provides all the information you need after you’ve set the desired tempo and the note part provides different temperaments and diapason. Touching a note will play the note, so you can also hear the different tones.

You can have even more…

Of course the above ones are only a few recommendations which have been working for me exceptionally well, but as you know, the app store is full of applications like these. Before purchasing anything, I suggest to search the internet for information, reviews, and recommendations to be sure the chosen app will serve you in the long run. It is important even though these apps are very cheap for what they offer.
