Recording podcasts on Macbook Air

you might consider making your own acoustic podcasting booth too like i did here below:

$25 vs. $300 for a commercial one

Spectral audio comparison I made below on Adobe Audition........left side of center marker is INSIDE the box, right side OUTSIDE

all variables identical other than the box

youll notice a lot of noise missing on the left, If I magnified it youd see a lot more noise on the right.

Aside from whatever Mic you use a new current Air model, any of them, will do what you need it to do for your podcasts.

I Do a lot of podcasting.

what kind of microphone? most mics made FOR computers BY computer people are pure junk.

Best mics are professional mics that are retrofitted for computers / USB.

Yes, absolutely, tons of people are doing podcasts on their Air.

Any Air is fine for same, consider a better mic however, such as a AT2020 USB

Dont use Garageband, use something good for recording such as the APP Amadeus, Twisted Wave, or Adobe Audition, or Sound Forge etc.

depending on what you have now. 😊

Just an aside:

If you run out of free space on your HD (`20% empty is recomended for VMEM and temp files) it can cause crashing. Once you've crashed a few times without booting into repair and repairing your boot drive, more crashing occurs as the MBD gets thrashed. This is true of any operating system.

Ouch, yes, I know all about that mic, its hideous at recording.

Without spending a lot, a professional Mic adapted for USB is the AT2020 USB
