Do i need good internet connection to upload the audiobooks or when i upload to the tracker my connection doesn't have nothing to do with ppl downloading?
My upload speed is only slightly better.
The average novel, if ripped to average 32 kbps, is a 2-300 MB. Dramatic readings, with music and sound effects needs more to do it justice.
(Whatever you do, listen to part of it to check that it sounds okay, especially the beginning and end to make sure it is complete and check the total duration is correct.)
When I initially seed it takes a few hours for the average book to get out.
As I have quite a few torrents running, when I start seeding a new one I select all the other torrents and pause them, so all the upload bandwidth goes to the new one.
I look at the "peers" tab in uTorrent and I can see all the peers connected to me and the percentage they have. Since all peers share what they have, once any of them gets to 100% then the number of seeds starts to explode. At that point the torrent is safely launched, and my own upload is not vital.
So just upload one book at a time, wait till each is safely seeded before starting another. Don't make multi-gigabyte packs that will take you a week to seed.
