My father for years has loved to sing and record himself with just his cellphone. I am planning to finally do a little setup for him but I am totally new to this. I believe he has a good speaker the harbinger MLS900 and got a Samson C01 condenser mic with a cheap 48V phantom power supply. Is it a must to have a computer ? Can he just connect the mic to the phantom power then to the speaker and just record ?
