I'm just getting started with home recording. Here is my current setup. Windows 10 Desktop PC 64 bit. Audacity software. Behringer Xenyx X1204USB mixer. MXL dynamic mic (2) I ususally do 1 track at at time, but sometimes I put acoustic guitar and vocal down together for me to learn the bass parts. Not me on the guitar and vocal. It seems I'm getting acceptable sound. Here is the question. The guitar player says I would get better sound if I use an interface instead of the mixer. Seems to me the mixer adds some features not available on the interfaces I have seen. Is he right?
