I purchased and tested over a dozen audio interfaces for the noise floor of the preamps, headphone output, volume of headphone output, frequency response of preamps, harmonics, distortion, latency and perceived sound quality. I talk about which audio interface is the best for various home studio setups, I announce winners for various categories such as best value, best sound quality and best features. I also make recommendations for various price points. I spent a lot of time testing and using these audio interfaces in various recording studio situations with singers, vocalists, acoustic guitar, electric guitar, bass guitar, piano, music production, professional recording studio, home music production studio for professional level of sound quality.
