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!

Create cycles with tone shapes of smoothly varying frequency by plotting frequency at specific times. Tap the library button to pick from a selection of sample tone shapes to get started. Tap in the plot view to add points with coordinates (frequency, time). Drag to move points, but limited by the neighbors time. Alternatively, drag in the draw tab to add points, then apply them to set the points in the plot view. Adjust the frequency range slider to limit the bandwidth. Adjust the duration slider to specify the cycle period. Finally, in the export view you can save the audio to a WAV file with a chosen number of cycles. The duration of the audio is limited by the maximum duration, which therefore also limits the number of cycles in the audio file.
