Ok guys i'm literally having a breakdown right now. I just don't listen back my voice or guitar while I'm recording on both logic & GarageBand. I simplified the setting by removing my audio interface & I cant even hear my voice through the built-in microphone.
I have :
- Macbook-system preferences-outpout:internal speakers & input:internal microphone
- Garageband-preferences-audio/midi-output device:built-in input & input device: built-in microphone
- Monitoring button at the track I want is on. I had some great ideas I just wanted to put down quickly.
HELP SERIOUSLY.
Oh not sure if it matters but i'm currently creating a TimeMachine backup on a hard drive.
Since Garageband is a commercial application for the recording of audio I'm sure that they would be able to help you get this sorted out. See for example the help online for "GarageBand for Mac: Turn on input monitoring for audio tracks" Recording using one input into two applications might be a tall order.
If you are simply trying to test whether your audio system can record and output at the same time you can use some audio applications. I can't help you with Mac, but on a Linux machine we have available for example the command
that will play back immediately all mike input.
