Simple LPTSND r0 - Covox Speech Thing
Simple LPTSND r0 - Mini Project
Simpler R2R sound adapter for the LPT port.
This uses 1% 0.6W metal film resistors, you can also safely take 0.1%.
But what raises the price. I do not think that at 8-bit resolution raushört that bit.
Some may prefer to use another capacitor.
But with the more treble also comes more interference from
Wikipedia:
The Covox Speech Thing (also known as Covox plug ) was a computer accessory for outputting digitized sounds. This is a primitive 8- bit - D / A converter (a R2R network) in the form of an adapter plug, which is connected to the printer port of the PC and so provides an analog output. The plug was widely used until the 1990s, because then proper sound cards were still very expensive. Also in the demo scene he was quite popular.
For notebooks, demos, MOD players and so on.
