I just created an Audio Spectrum Analyser app and it’s proved very popular. Turn your Android device into an audio spectrum analysis tool and break into safes – um, please don’t use it for that 😉 The app uses a Fast Fourier Transform (FFT) algorithm to analyse sound and has some features not found in similar apps (such as exporting audio snapshot data). Check it out!
For those interested in helping me correct or add more translations, see the github repo here.
There are many uses for spectrum analyzers, such as:
• Assessing environmental noise for health and safety
• Sound checking speaker setups, PA systems and in-car stereos
• Identifying audio signals obscured to the human ear by noise
• Testing the microphone on your device
• Comparing the quality of different brands of headphones
• Testing signal generators
• Tuning musical instruments
• Measuring audio signals just outside human perception. As people age over 20 years, their aural perception range drops well below 21 kHz
Speccy has also been used to find gas leaks and even hunt ghosts, apparently!
For calibrating audio equipment or mixing, have a read of this article, this one, or watch this useful video:
Just looking through some old work and found a banner I had created years ago. I know, I know, a banner – but, as banners go, it’s rather awesome 🙂
I created this for the BBC, to advertise a game related to one of their TV shows. It employs some pretty clever maths to animate some creepy vines which actually reach out to ‘grab’ your mouse cursor – have a play! (requires Flash)
If you’re on mobile, or don’t have Flash enabled on your browser, you can see the banner in action below:
Winning two DMA awards back in 2009, I thought I’d give a quick insight into how the animation effects in this piece were achieved.
I worked with Scott Bedford on this site for Carlson Marketing, for the Lurpak ‘Breakfast’ campaign. I created all the animation prototypes for the various effects used throughout the site, some of which can be seen here. I’m most proud of the crumbs animation and the code-generated interactive steam effect – as you’ll see in the video below.
What I love even more than doing animation, is doing challenging code-driven animation.
This banner actually won some awards apparently, including NMA Campaign of the Month and was shortlisted for Cannes Lions.The line dynamics itself is just Hooke’s law stuff – basic physics. Took some experimentation to get a smooth curve drawn through a series of points (basicaly, the control points of your previous and next points need to be in line).
If you can’t see the demo above because you’re on mobile, or don’t have Flash enabled on your browser, you can see the banner in action below:
The cars follow one of the line’s points with differing elasticity and damping, but the real pain in the backside was drawing the dashed line via code, in crummy ActionScript. Luckily, I’m a persistent bastard 🙂 Read more about it on Bannerblog.
