Later on, I will verify their decoding of the cassette tape using my own filters I shall write for the raw waveform software: Goldwave.

So why would you do something like that? Can't you just take their word for it?

Wow, it's like finding a rare artifact from a Mayan historic site...

The Apple I had a total of 8192 bytes of memory (8KB). Since there was no hard drive or any other persistent storage device integrated directly into the hardware, you had to enter the language interpreter (Apple BASIC) manually every time you start the computer (or use the cassette). You had to use the first 4096 bytes for the interpreter, and the 4096 remaining bytes for whatever program you wanted to code and run...

Why wouldn't they have verified the file themselves? It would have been a serious oversight to only attempt decoding it through one method.

They don't have the file...
You can't possibly have an original file of Apple I Basic, because the Apple I didn't have any file system...
At best, you can ask Woz to give you his pile of handwritten notes...
