This tool helps remove noise when converting mono recording in older mediums to stereo.
Mono-a-Mono is an audio restoration program for creating stereo recordings from vintage media such as 78 rpm records, cylinder recordings, and any other mono recording. It helps enhance the quality of the output stereo recording by filtering the scratch, pop, cackle, etc. noises associated with these recording. The cleaner recording then could be played through your modern stereo music players. If you have a plan to convert your old stock of records and convert them once for all to digital format and save these from further deterioration, this tool could be quite handy. It can enhance digital recordings of old records (whether 78, 45, or 33 rpm, shellac, acetate or vinyl), audio tapes (reel-to-reel or cassette), or even cylinder recordings, provided only that the playback and digitization of the signal has been performed in stereo, but the original source was mono.
The tool uses a two-step process. In the first step, it uses a simple method to remove the clicks. Other noise components are removed through implementation of a higher order adaptive filter. Most noise components are rendered inaudible with this process. No new artifacts are produced either. It detects noises that are present in both the stereo channels in equal strength (actual music will not have that) and removes such components, thereby removing all the noise. This tool can be used as a vocal remover as well. This is a good tool and is a good candidate for trial. No configuration or tweaking is really required.
