We offer two levels of service on our Audio Transfers so the answer depends on which you choose. Our Archival Level is our most economical and will not improve or change the audio in any way. Our Professional Level is slightly more, but includes improvements such as noise-reduction, volume maximization, digital equalization, as well as editing and track separation. Our improvement processes are designed to be highly effective yet very affordable. We do not do the type of specialized tweaking you can find in high-end audio-only mastering houses.
