Hi - Background: I have been using the real-time waveform/spectrum (RTSpect) and spectrogram (RTGram) Windows apps from UCL ( 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. Cheers, Daniel
