Audio Ringbuffer
if you want to build instant music in apps from single sounds, it is important that the samples are absolutely synchron and perfect in timing. So you should send one single stream to the system where all the sounds and instruments and effects are already placed. Here I demonstrate how to combine sounds to a stream in a ringbuffer. A timer steps through this ringbuffer and sends the current chunk to the AudioStreamer to feed it just in time in the very last moment.

The clock uses Text To Speech to read the time. It is set as a service so it reads time hourly at the background. Leave the clock running in your office so at least once every hour you get to hear something that makes sense.

real gallery project
I was planning to make an image selector library like the one used in WhatsApp and Telegram but i ran out of time so i''d like to share this project as it may be useful for someone. It is working and can be used for many proposes (tested on API-21 to API-28) , it may need a few little optimizations. It has all standard gallery features (albums, scrolling, pinch to zoom ...)
