Recording Voice Memos
Voice Memos lets you use iPod touch as a portable recording device.
Voice Memos uses the internal microphone in iPod touch 4th generation. To use
Voice Memos on iPod touch 3rd generation, connect the Apple Earphones with
Remote and Mic or a compatible accessory with a microphone. These include
Apple-branded earbuds and authorized third-party accessories marked with the
Apple “Made for iPod” logo.
You can adjust the recording level by moving the microphone closer to or further
away from what you’re recording. For better recording quality, the loudest level on
the level meter should be between –3 dB and 0 dB.
