"Good" audio can mean all kinds of things, as can "bad" audio. It's a very subjective thing. Sure, there can be very obvious issues, particularly with old audio on cassette tapes, or something recorded on a cell phone in a less than ideal environment. Either way, if you have audio that you want to sound "better", send me a message. We'll go over what you're looking to have done, whether it be a simple conversion to digital, or a restoration. I'll handle your physical copies with care and will reproduce your audio in digital format. I can perform a simple conversion or a full cleanup, removing line noise and other artifcats.
Some typical sound issues are:
The goal of audio repair is to remove as many problem spots as we can without affecting the "good" parts. For instance, if you have a cassette tape from the 80s or 90s of your band practicing and the tape is so worn that the constant hiss is more prominent than the music, or if there are imperfections on the tape that create that "squealy" sound, those are the things I can help remove. Or, at the very least, reduce them to the point that they are no longer distractions. Every tape or other piece of audio is different, and after listening to it, I'll let you know how much I can help. Some audio may be too damaged to fix completely, but in most cases, we can make significant improvements.
Here's a couple snippets from a cassette tape, recorded in 1992. The audio was transferred to a PC via standard audio cables from a tape deck to an 1/8 jack in a sound card. In the original, you'll hear exactly what you would expect; failry poor quality, a flat sound with no "oomph". But also, we have a couple of odd skips at the eight-second mark.
