Audio Kit is a collection of four applications which are essential for those working in audio and sound. A real time Spectrum Analyser, a Scope to display waveforms, an SPL (sound pressure level) Meter, and a sine wave Signal Generator.
-View a real time spectrum of audio with the Spectrum Analyser
-View the actual waveform of the audio signal with the Scope
-An SPL Meter provides measurement of sound levels using an A-weighting
-The Signal Generator provides a sine wave output up to 20,000Hz in 1 Hz steps.
FFT (Fast Fourier Transform) is used to calculate the frequencies in the Spectrum Analyser and these are displayed in real time. The frequency is displayed in either logarithmic or linear scale.
The display of the Scope can be adjusted easily using pinch gestures in both horizontal and vertical directions. Zero crossing detection of the waveform provides a smooth display and can be set to either positive or negative direction zero crossing.
There is a screen capture facility in both the Spectrum Analyser and the Scope allowing you to save the spectra and waveforms for future reference.
SPL Meter continuously displays the sound pressure level, and has minimum and maximum displays also.
The output of the Signal Generator can be viewed on the other parts of the App.
Frequency is selected using picker wheels and allows for accurate control of frequency to within 1Hz. Volume is continuously adjustable, and there is a switch to quickly turn off volume and quickly reset it to the previously set volume.
All parts of the App have direct access to a help document.
I remember taking to a guy from TinkerIT about Arduino and he thought that a large proportion of Arduinos bought remained in draws unused.
Well if you’ve been meaning to get going with your Arduino then maybe this video will help. Via Make.
When I first heard that TabToolKit from Agile Partners had won a design award I was really pleased. Apart from the fact that TabToolKit is a good app for the iPhone and iPad, the fact that they won an Apple design award is a big step forward not only for Agile Partners who make great music apps, but for the whole mobile music community.
It is so important because it makes a statement that mobile music creation and applications aren’t just toys any more, they are tools that can help musicians in a whole host of ways. It is also important because the music category of the app store isn’t massive when compared to games and some other areas. So this kind of recognition is really significant.
So, what was it that made TabToolKit win the award? The criteria for the award (technical excellence, innovation, superior technology adoption, high performance, outstanding design) align nicely with what Agile Partners consider to be important, especially outstanding design.
I’ve been in touch with Agile Partners and they answered they gave me some Q&A which gives you an insight into how they designed TabToolKit:
I think that it is great that TabToolKit won a design award, not just for them, but for mobile music as a whole. I hope that next year we continue to see mobile music apps showing up in these and other awards.
Another excellent promo code give away today. This time for MultiTrack 2.0. I have 5 promo codes to give away for this excellent app. To enter the competition all you need to do is to answer this question.
Not much of a video, but a good DS-10 track.
