Short Version ("TL:DR"):
My parent er landlord screamed and or banged pots and pans by my room from 3h to 7h (3AM to 7AM) and did not stop the entire time (but my door was closed and not open so I could not see just hear), how do I prove that happened that very long-term, with just my smartphone to timestamp?
At exactly 03h07, a heavy machinery WM.com dumpster truck backs in ten (10) meters away, starts revving their engine like a racecar and running their forklift at extremely high decibels, reverberations physically shaking me and my home (and my neighbors, does that matter?). How do I prove, with just the sound/audio signature recorded from my smartphone, that I was woken by that at the brink of dawn 3:07AM?
Long Version ("Extended/Detailed"):
What best practices to prove as evidence that that sound was at that timestamp? Evidentiarily best/wisest is a live stream to timestamp audio? What live audio stream (and is radio/tv news, what about reruns?) should a user use to Timestamp Audio? What is suggested, if I need to be able to prove that a sound happened and (is clockable as proof of) at a certain exact time.
Any self-recorded audio would be the same example, can you tell me exactly what second a word was said in Universal Standard Time for each word?
My personal angle, to use me as just one example, was from asking by search engine speaking "best live audio stream (is radio/TV news?) to timestamp audio?" I meant 'What is the suggested method for timestamping/dating theaudio recording I just made' (note the timestamp, as the trusted time the record began, at the beginning of the YT title and .wav record file name, which you have to trust the time written by me/you the User) and https://steemit.com/csychology/@scribe/qd9npv to prove my experience from seconds ago.
Well because of technological reasons, partly done to follow professional workflow standards, posting process from www.AudioShip.io to www.YouTube.com took/delayed hours for, again, mainly technology reasons, seemingly another Digital Divide beyond what would be the value a "newspaper in the photo" is, for there is not an equivalent for audio. Comparatively, I can send a timestampable sexting message with greater proofing than a single word I say with my audible mouth [scroll feature to track linear sound is emotionally tolling (literally an emotional experience to rehear, a page of text does not bite like an hour of audio equivalently, and the evidence process is generally manual), to make matters difficult] as sound waves, which is very technically provable.
Is radio/TV news verifiable to the second, a secure reference point, what about reruns/repeats? If I change to a radio channel and the commercial is the same as before, that's not proof of life, er proof of timestamp, correct?
I am worried that try to timestamp I just made is not enough proof for the legal system, if I did not activate a radio or TV with some verifiable knowledge '
I know that sound happened at that time because I heard the radio anchor say that the first time then, that was that issue's first ever word, very first words'.
I am not asking Recognition of timing information by sound device about if my sound recorder knows what min/sec I am at in the tracking bar. The issue is proving as a matter of fact that what the "sound device" thinks is the time is not the (painfully sadly for record-keeping standards if) only proof we have to ask for. Why should I (scientifically, evidentiarily) trust my/your tape recorder said that cursed/claimed/alleged/accused/"documented" hexspeak of a timestamp?
I am asking how to mechanically or socially make sure for myself and others that that sound happened at that time. Is that a security feature, do any sound recorders record timestamps of pending audio streams before you're able to save fully to Google Drive, in my test case? Is there an audio channel that works as a timestamp?
Do we need a radio frequency AM/FM/HAM that has, a voice counting a clock every second?, a newscast that never has commercials or repeating sections?, or a constantly changing rhythym and sound or whatever, to 100% know (like a password for sound itself (audible timestamp hash/signature/password/watermark), maybe a blockchain for sound itself), can we verify that sound definitely happened at that time the sound happened, that sound means that timedatestamp?
