Jill wants to find an app where she can record herself playing a few different instruments and then play them all together. Leo says there aren't many apps for audio recording and play back on Android because of a massive latency bug. Leo believes it's in the kernel, and they haven't fixed it yet. She can find out more about it at superpowered.com.
multi track recording
Shannon is a southern gospel singer and they sing in 4 track harmony. He's looking for good software that can balance the volume and gain when recording separately during a live performance. Leo says that all recording software has that capability, and he can always use hardware to do it with a Telos compression/expansion module. It also protects against popping and clipping. Audacity is free and he could find a plugin for it that can work. It's available on all platforms, too.
