I would appreciate your advice on the following questions regarding the
audio interface on the audiostix-2 and GPSstix expansion boards:
(1) Is the audio interface on the audiostix-2 and GPSstix full duplex?
I.e. will it support recording and playback at the same time?
(2) Does the audio input operate at mic or line level? Does the audio
output operate on headphone or line level? In other words, will I need
to get an additional mic and/or headphone preamp?
Any hints would be greatly appreciated!
