Technical and scientific discussion of amps, cables and other topics.

Seriously, John

slow down for a moment and reread Mike's question.

"In designing "lossless" codecs, like MPEG4 (Apple Lossless), are listening tests used, or are the files simply compared?"

That question implies two concepts:

1. The answer must be from the designer's standpoint.
2. The answer relates to the testing process.

While you answered a question, it was not Mike's. Let's review your answer.

Lossless, as far as I know, means that the files are bitwise identical input and output.

Let's test your answer against the two implied concepts.

1. Is that answer from a designer's standpoint? No. The question you advance following the answer clarifies that you are not a codec designer.
2. Does that answer address the testing methodology? No. It merely states your understanding as to the definition of a lossless codec.

It would seem that you frequently mean something different from what you say. Then retreat to the paranoid "y'all are all lyin' about me" corner.

Let's imagine for a moment that your response was more like this to Mike's response:

I thought I answered your question. I believe that designers simply compare the bitstream as the means of testing as opposed to using listening tests or any other means. Was I not clear in my answer?

That is what language is all about. Clear thoughts and responses free from ambiguity with no need for interpretation. It really shouldn't be all that difficult or adversarial as you frequently make it.
