You can sync voice memos with the iTunes library on your computer, and listen to them on your computer or sync them with another iPod touch or iPhone.
When you delete a synced voice memo from iTunes, it stays on the device where it was recorded, but it’s deleted from any other iPod touch or iPhone you synced. If you delete a synced voice memo on iPod touch, it’s copied back to iPod touch the next time you sync with iTunes, but you can’t sync that copy back to iTunes a second time.
Sync voice memos with iTunes. Connect iPod touch to your computer. Then in iTunes, select iPod touch. Select Music at the top of the screen, select Sync Music, select “Include voice memos,” then click Apply.
Voice memos synced from iPod touch to your computer appear in the Music list and in the Voice Memos playlist in iTunes. Voice memos synced from your computer appear in the Voice Memos app on iPod touch (but not in the Music app).
