I am offering my service to transfer old (or recently made) audio cassette tapes to MP3 format. Price includes digitally emailed MP3, but an extra cost of 0.0003 BTC for a CD, (Genuine Verbatim, Azo Dye Disks, not crappy CMC disks).
The tapes will be transferred using a modified WM-D6C walkman with a Quartz-Locked motor (Super-D6C, see here:
http://www.walkman-archive.com/articles/upgraded_super-d6c.html). Price includes a quick noise reduction and clean up of the audio, although i can leave noise reduction out if the buyer would prefer and/or provided raw PCM WAV files or raw audacity files. Correction of speed will also be carried out if its bad on the original recording. The WM-D6C is connected via Line Out, to Line In, not a headphone port to microphone jack, nor is it one of those Chinese made USB tape transfer things which does poor quality recordings. OCD means i will squeeze out every last drop of what I can from the original tapes, although you will only be as good as the original recording, minus some noise.
For damaged (snapped or mangled) tapes, I add an extra 0.0003 BTC charge.
I accept payment in BTC/LTC.
If anyone is interested, let me know! I can also transfer tapes encoded with Dolby B and Dolby C, the modified WM-D6C does not have the 'pumping' well known with dolby C, as its internal electronics have been re calibrated, including the replacement of old capacitors, etc.
As recorded tapes are often sentimental, and in fact i still make cassette tapes of family etc for fun to this day, and ever since my mother died storage of my older ones and archiving them has been crucial, your tapes will be treated with the utmost respect.
