WebYou can amplify (e.g. in Audacity) with some fairly low noise and good signal, if you need it louder (e.g. normalization). You need to be careful, because it definitely amplifies noise to some degree also. The Fethead amplifies the signal, pre- preamp, however, so some of the H6 noise floor problems are preempted.
