LineIn
Inside The Lines
LineIn is a simple application for OS X to enable the soft playthru of audio from input devices. In simpler terms, you can use LineIn to play sound coming in through a microphone or any other device plugged in to your Sound In port, just as was once available with OS 9's "Play input through output device" option.
New in 2.3:
A long-standing issue with latency in LineIn has finally been cured! We've also added a menu item for toggling play-thru. -
MakeiPhoneRingtone
It Makes iPhone Ringtones!
MakeiPhoneRingtone is a quick drag and drop utility to turn AAC files into ringtones for your iPhone. Make ringtones from audio you already own, instead of purchasing it again and again.
Fission Recommended
While MakeiPhoneRingtone is still available, we recommend using Fission for more robust ringtone editing and creation. Fission does not require AAC files (as MakeiPhoneRingtone does) and will work with almost any audio file.
You can edit your file right in Fission and choose Save as iPhone Ringtone right in Fission's File menu. Check out Fission now. -
PongSaver

New in PongSaver 2.1.1:
PongSaver is now signed with Apple's newest Developer ID requirements, for compatibility with Gatekeeper. It also requires Mac OS X 10.7 (Lion) or higher. -
Soundflower
Soundflower is a Mac OS X kernel extension that enables audio to be passed between applications. It acts as a virtual audio device, with both inputs and outputs. With it, any audio application can send and receive audio.
