Citruxxx pwede po kayo mag request din dito.
Medyo mahirap po mag hanap ng source ng audiobooks due to the file size. So if may makita ka usually naka upload sa sites like Usenet na kailangan mo mag ρrémíùm (given the size of most audiobooks range between 300mb - 1GB).
Meron akong server and access sa trackers kaya nakaka share ako ng audiobooks to those who need them. Otherwise you can try VK (website and app). Ang problem is kailangan mo mag pay para maka download ng audiobooks pero pwede ka mag stream. Another downside is limited lang ang books nandun, mostly fiction pero madami parin. If gusto mo lang ng any audiobook to pass time and nothing specific, then ok na yan si VK.
Another option is through Telegram channels. Again, no search option sa isang database lang if you want something specific pero madaming shares daily for ebooks. For audiobooks sobrang konti lang due to the filesize. I, for one, own a telegram channel pero nahihirapan ako mag upload ng audiobooks due to the size pag inupload to Telegram.
However, if meron kang specific titles in mind, pwede ka mag request dito and I'll upload as many as you want. I own a 1GBPs server don ko dinadownload and ina upload lahat.
