Thanks very much for posting this. Very interesting recordings. If you do very much of this kind of thing, and, since you mention "the crackles", I suggest using one of the "lossless" compression formats (ALAC, FLAC, MPEG-4, etc) rather than a "lossy" one like AAC/mp3/ogg-vorbis/etc because any of the latter literally discard any data which fall outside their compression parameters. That is, there is not only amplitude compression, there is also frequency compression; both accomplished by simply excluding amplitude and frequency ranges outside those considered "necessary" to have enough program to be recognizable. There are pretty good discussions of this subject at these two locations: http://en.wikipedia.org/wiki/Lossy_data_compression and http://en.wikipedia.org/wiki/Lossless_data_compression If you listen primarily through an iWhatever using earbuds, or when driving about, then a lossy compression algorithm is probably the way to go. The choice of which algorithm is probably largely going to have to do with if you use Apple products or PC/other platforms. Stick with whatever is native for whatever device(s) you are using for best/most consistent results. If you are after relatively serious archival storage and retrieval (and, you listen primarily via reasonably good equipment in a relatively quiet environment), then you'll probably wind up preferring a lossless algorithm. While there are nearly as many debates about which of these to use as there are about what kinds of voicing techniques to use on pianos, it seems like most people wind up using FLAC, WAV or AIFF. Each have advantages and disadvantages; and there is lots to read on the web about which does what the best. Much depends on your goals for the end product. I've been doing restoration and digitizing of older recordings (vinyl, tape, wire, etc) for a long time; and do have some suggestions for products to help with this process. For general "ripping" of recordings from CDs, it's hard to beat dBpoweramp. It's reasonably priced, fairly easy to learn, and, importantly, doesn't really tacitly require a dedicated machine/workstation. Here's a link: http://www.dbpoweramp.com/ For more "serious" and/or involved projects, including ones that require at least some degree of electronic editing, GoldWave is the value-for-cost leader, hands-down. Here's a link: http://www.goldwave.com/ Both of these have a variety of "add-ons" and/or "plug-ins" which provide additional functionality, including "crackle" diminution (it really cannot be "removed" with products built at this price-point). Some of these add-ons/plug-ins are free, others incur additional costs. I suspect that, between them, the above two products will do about 99% of what most people want that isn't already covered by iTunes, whatever M$ is calling the latest version of MediaPlayer, or any number of shareware products. If you want to get into the higher end of things, the cost goes up fairly quickly. The fairly basic set of software tools I regularly use have a total current purchase price of nearly 20K USD (although at least one of them may be available for less in the EU). Moreover, in order for them to function efficiently and effectively, require a fairly powerful dedicated workstation. Also, while products like these were originally developed for various Apple platforms, more recent programs have been designed largely for either dedicated platforms or Windows. If you want any additional information, I'll be glad to help out as I can. This area can get very complicated very quickly. I've been doing it for my own purposes and for a number of interested private clients for quite a while and think that one could go just as far off the deep end here as one can trying to tune a unison.... Kind regards. Horace
