Re: Real-time spectrogram for Mac
As a follow up, I remembered that I had put together compiled binaries of the LiveSpectrogram for a demo I did at my son's school. ÂYou can see the "handout" I made at:
.. which links to the downloads for Mac, Windows, and Linux at:
When you click the Mac download, you get a folder LiveSpectrogram_logf.macosx (this version uses a logarithmic frequency axis for more "perceptual" scaling); inside the folder is a file calledÂLiveSpectrogram_logf.app, which has the java coffeecup icon. ÂDouble-clicking that should run the spectrogram, which will start displaying analysis of the default sound input (usually the computer's internal mic).Â
When using this in class, I use SoundFlowerÂhttp://cycling74.com/soundflower-landing-page/
to route the output of programs (e.g., sound demos in PureData) directly into the spectrogram. ÂIt's a little bit temperamental, but it's great to be able to see the analysis of sound generation without any background noise.

I wrote my own real-time spectrogram that runs on the Mac in the very fun Processing environment (which is basically a front-end and some wrappers on Java). Â
If you install the free processing environment from http://processing.org
, you can download and run my "sketch" from:
I have made a lot of variants on the basic spectrogram (with waveforms, with pause, log scale) etc. if this one isn't quite what you need. ÂIt's quite easy to compile a Processing sketch into a stand-alone binary, I just didn't bother because it's nice to be able to change it rapidly.

Background: I have been using the real-time waveform/spectrum (RTSpect) and spectrogram (RTGram) Windows apps from UCL (http://www.phon.ucl.ac.uk/resource/software.php) for several years for teaching and outreach/public engagement as very easy to use to achieve intended results.
Question: Is there anything similar out there for Mac/OSX?
I've had a bit of a search with no luck; needs to be real-time and similarly easy to use for a varied audience. I'm aware of iPad apps that do something similar but am looking for something for Macbook.
Many thanks in advance for any leads.
