One of the more popular items in our range of modules is the MIC: Microphone Sound Input module, which is ideal for capturing sound and converting it into analogue signals and also the sound pressure level. Lately there has been some discussion about the difference between the output from the microphone and it's relationship to the SPL level, and how they can differ.
Angus from Freetronics has publsihed a new video to answer these questions and more, by demonstrating the two outputs and explaining the background and more with the use of a DSO to display the results. It's an interesting video and we hope will answer your questions as to how our MIC: module can be harnessed:
For more information about the MIC: module, visit the product page or discuss in our support forum. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
To test audio sampling yourself you can make an easy start with our Freetronics MIC: microphone and sound module.
The MIC: contains an integrated dual signal amplifier converts the sound to separate channels for pulse / frequency measurement, and sound volume (pressure) level. Designed to connect straight to an Arduino compatible microcontroller, Analog to Digital converter, or many other circuits. For more information and to order click here.
