Beep Buddy is designed to be a handy reference tool of musicians and sound manglers. As a developer and musician, I had a desire for simple tools that work quickly, intuitively, and are accessible to as many people as possible. Primary Features 1. Note Info - Get the frequency for a note, includes a full list of note information of a standard piano keyboard. Use the filters on the left to narrow the list down by note. 2. Delay Calculator - Get a list of delay times in useful subdivisions for a particular BPM. Use the filters on the left to narrow the list down by note, triplet, and dotted. 3. Inspiration - (This section is fairly limited currently and sort of strange) Create a fake word. It should be something you can pronounce. This is a feature on some devices I’ve used and find it useful when I just need a name for something. Rawr!
