jjss49 - that makes sense. I'm just curious as to how an approach that is very different could do a **better** job of re-creating the analog output than a reversal of the process that put the analog into digital form in the first place. But I am ready to abandon this inquiry because it isn't a burning question - just a curiosity. |
OP, you are on the right track, be aware that conventionally in most applications the performance of professional A/D convertors (in terms of accurately capturing the analog signal) actually exceed the performance of even the best D/A convertors. Thus it becomes a matter of which technology one prefers to recreate the original analog information contained within the captured digital audio data stream. |
I think a lot of DA conversion is filtering noise causing artifacts from the process and compensating for clock or other errors. AD conversion doesn’t have the same filtering and noise issues. By the nature of the process any frequencies above half the sampling rate are simply lost without a trace. The clock on the other hand is very important. It’s a different process. Think of it more like a claw hammer than a screwdriver. |
