I have a low-end home studio that I am building (in my garage), and am looking for a decent compressor to add to my collection of equipment. Unfortunately, I am painfully ignorant when it comes to audio compression, gates, and filters. I record mostly vocals, and unfortunately my recordings are ugly uncompressed audio and has a slight hiss to it. Word on the street is that a hiss can be filtered out by a gate or filter, and a decent compressor can also help. Basically, I'm looking for a compressor that is compatible with a mixing board and 4 microphones, as well as something that can help make the audio sound clean and remove a slight hiss. Below are just a few pieces of equipment that I already own: 4 Shure SM58 Microphones Behringer XENYX X1622USB Audio Interface Furman Merit Series Power Conditioner (M-8x) M-Audio Studiophile BX8a Deluxe Studio Monitors Sony SoundForge Recording Software Mogami Microphone Cables HP Laptop I'm not sure the price of a decent compressor - I've seen everything from $150 to $4000. I'm looking for a decent compressor that won't give me a heart attack when I see the bill. Thanks! FYI: It's a podcast recording studio. If it makes a difference.
