      From: ol.sc@web.de              Hi,              The other day I finalized A2Stream, a program that simultaneously       receives a file from any HTTP server and plays it through the stock       Apple II speaker circuit.              Some personal background: For many years by now, I've developed and       maintained Ethernet software for the Apple II. My focus was always on       practicability, portability and reusablitiy. Often I've invested in       tools, trying to enable others to create something cool. However, for       once I wanted to do the opposite: Showing off with a tech demo that       pushes boundaries.              A2Stream follows the general concept of DAC522, but with an improved       audio quality using pulse-width modulation at 22050Hz sample rate with       ~5.17 bit resolution. This sample rate is kept consistent during the       complete playback, so A2Stream is supposed to sound better than       everything else using Apple II speaker circuit so far.              Project site - https://github.com/oliverschmidt/A2Stream       Demo video - https://youtu.be/YcYEnYsI-_M              Have fun,       Oliver              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
