There’s a useful in-depth review of Mono-a-Mono, written by a professional audio engineer who actually knows what he’s talking about, at the archived TDL Technology site.
To hear what it can do with wide range of music and speech, have a browse around my personal web site. It includes a pretty random selection of 78s from my collection, including a couple which were cracked (not just scratched – the record was split right through – only held together by the paper label), some were badly worn, and some badly pressed. You can get a pretty good idea of what to expect from Mono-a-Mono by listening to these.
To hear exactly how effective Mono-a-Mono can be at removing noise, try the “before-and-after” recordings below. They’re from 78s dated between 1930 and 1950. For each one, there are two files, one the “original” stereo recording (played back using RIAA equalisation), and one “cleaned” with Mono-a-Mono. The “original” files are the same recordings used as input to Mono-a-Mono, but converted to MP3 format. The “cleaned” files are the corresponding outputs of Mono-a-Mono, again converted to MP3 format.
For the “cleaned” files, Mono-a-Mono’s Wizard function was used to set the processing controls. The Wizard’s “Background Hiss”, “Pops’n’Clicks”, and “Wear’n’Tear” controls were all set to mid-range values. No individual customisation was performed.
