how does it work?
LPs usually benefit from cleaning - we use a solution of isopropyl
alcohol - which removes any surface contaminants and has the added
benefit of reducing static, helping to keep dust at bay.
Next we record the material onto a workstation using an appropriate combination of high quality components (turntable, pre-amp, tape deck, sound card, etc). The sound card converts the analog signal into digital (.wav) format.
Then the clever stuff begins. We use the best available commercial software especially designed for audio restoration - if the source is vinyl, the first task is to remove impulse noise such as clicks and crackles. Next is broadband noise reduction (for tapes this is usually the first step, i.e. reducing tape hiss).
When noise levels are acceptable, we carry out equalization (not always necessary) to adjust frequency response and normalisation (loudness), before splitting into individual tracks and either writing to a CD or converting to mp3 or another digital format.
CDs are supplied in jewel cases with printed labels and printed paper inserts with track listings.
