OT: Software Ap for Recording Audio and Video on Laptop

[Hardlyrob]

Hey Forum;
I've been trying to record quality video and audio for various musical performances on my laptop. But the setting on the microphone are maxed out, and the sound quality is terrible at anything but the lowest volume. We bought an external USB microphone which helped, but there does not seem to be a way to lower the mic input levels below screaming.

Any thoughts to Aps that would allow us to set levels, and probably do some editing / mixing. We're recording piano alone, and voice and piano.

Thanks!

Rob
