AudioShare (2.7.4) is a file organizer for iOS that helps one record from various applications, apply special effects, perform editing, and then save the file locally or to other locations, such as Dropbox. It is very easy to use, efficient, and extremely handy - serving a number of really needed functions. I discovered this App, and learned how … [Read more...]
Teensy Drum Synthesizer
I've recently started to learn about and practice with Teensy's audio library, and their companion shield. The reason that I have gone this route is that the Mozzi library uses lower fidelity DACs that result in too much noise, even though they promise 12 bits. There are just too many artifacts. I have built a simple drum synthesizer using the … [Read more...]
Step Sequencer Using Mozzi
Recently completed is a step sequencer that combines many different subsystems to yield a nice sounding and playful platform. We hope that this provides enough documentation so that when I come back to this project, I can actually get up to speed quickly and accurately. I have decided to document projects both on line via 47meters & via a … [Read more...]
ARM Capacitance Sensor
The Teensy 3.2 is an amazing small Arduino, and it uses a powerful ARM processor running at 96 MHz. One of the benefits of this part is that it has a multitude of sensor inputs (on the order of 12) that can be used as switches or similar sensors. This is a plot from a sketch with approximately 1 ms sample rate (I think it is more like 10 ms … [Read more...]
Amazon Headphones & Amplifier
Amazon has a pair of very inexpensive on the ear headphones that I thought would be perfect for a variety of low fidelity uses where I did not want to bother with in the ear/earbud type transducers. Also, it provides a good balance of noise blocking, comfort and bass response. These headphones, sold under their 'Basics' label are very inexpensive … [Read more...]
Posting Photos in Lightroom CC
I've switched to using Adobe's CC photo sharing facility for sharing photographs with others. Although you can not add text, you can show a nice 'light table' image of all photos at once, and you can then click on photos that you like. Here are the instructions on how to do this from Lightroom's help: Step 1 of 6 Sign in to Lightroom From … [Read more...]
