This is the audiolog collection. JR kept it's location in secret for a long time, for a reason. This is a giant collection, and if someone has unrestrained access to them, it's easy to fixate and burn out because of the sheer size.
For a long time, people who found it were asked to keep it in secret, and tell JR how they did it, to prevent others finding it.
The intended way of searching for them is the Gigglette audiolog player: http://www.farragofiction.com/AudioLogs/?passPhrase=hello_world
You write in a phrase, and if it's valid, it plays, if it isn't, parts of audiologs with similar names get distorted together. The better the guess, the clearer the audio.
The audiologs you found can be viewed here, they sometimes contain linked images, paldemic chatlogs, transcripts or gigglesnort: http://www.farragofiction.com/AudioLogs/collection.html
Krysal made a doc about the system and a bit of organization, here.
Here is the Farrago wiki with the traditionally found audiologs, and their transcripts: https://farragofiction.fandom.com/wiki/AudioLogs
During Zampanio, the audiologs' location was intentionally leaked by JR.
Here is a more complete collection and transcripts by the guide: https://zampaniosim.fandom.com/wiki/Audiologs
I think this is really similar, but here is the document they also shared.
I won't spell the location out here, but it's realitevely easy to find it now.
I've made a little tool for myself to listen to all the audiologs after each other. It needs a bit of assistance in Firefox, since the source of the audio is a http, and not a https site, but it can be solved by enabling mixed content. Update: it's completely broken in neociteis, because it automatically blocks http. I'll just leave it here then.
Proceed with caution.
