I have quite a number of old cassettes that I would like to convert to a digital format. Some of them are from as long ago as the 1940s (most likely copied to cassette from other formats cause I don't think std. cassettes were around back then - don't know when they came out though).
I have fairly recently (within the past several months) done some temporary digitizing of several cassettes (so I can put them on an mp3 CD player for personal listening) by putting them one at a time into a portable cassette player, plugging them into an mp3 player with direct line-in encoding, and recording at about 128kbps (which was ok for what I was using the mp3 files for). However, I'd like to redo those (and also add several hundred (if I counted correctly - could be in the thousands) tapes to the project) in as good of a quality as is possible. Especially for the older tapes that may have degraded some (and may not play as well as may be possible on the cheap portable player I was using), I'd like to get as good of a quality as I can out of them.
So.... what are some recommendations for a good cassette deck? I'd like as good of an audio quality as possible, and I also want the playback speed to be calibrated properly. At the minimum, I want a single-well deck, preferably with auto-reverse (configurable so I can have it play side A, then reverse and play side B, then stop). Ideally, I'd like a dual (or more) well player that will allow me to play back at high speed (in multiples of 2x preferably), with the capability of outputting the sound at high enough frequency to get all the info (for example, if it would have output 44.1kHz at 1x speed, it would output 176.4kHz at 4x speed. (Of course, if I go for high-speed playback, then I would definitely need a higher end sound card on the computer. Speaking of which, I probably need to buy a whole new computer for what I'm planning to do - my dad's computer that I'm using right now only has a 1.4GHz CPU, a couple 7200rpm HDs that ultimately won't have nearly enough space for the data I'll be putting on, 256MB RAM, Windows 2000, and on-board sound (a few years old).)
While I'm at it, since I'll need to get a new(er) computer to do this efficiently (which seems to be turning my project from a $100+ project into a $4000+ project!), what would be some things you guys would recommend? I'm thinking a fairly fast Core 2 Duo (or AMD equivalent) at least, minimum 2GB RAM, plenty of HD space (at least 500GB), Windows XP (maybe Vista), etc. What would be some good sound cards that are capable of multiple inputs (if, say, for example, I decide to record 8 to 12 cassettes or more simultaneously), and very high sample rates (if for example I use cassette players (if they exist) that play back at high speed and output at high sample rates)?
Also, what would be a good codec to encode the masters (digital files) to? Obviously not MP3, cause it's lossy (although I could live with 128-160kbps mp3, maybe lower in some cases depending on the original source quality, for casual listening on a portable media player), but I do want it compressed (losslessly, of course). One thing I would like to keep in mind, is not to waste bits that aren't needed, for example if I was just recording straight to WAVE, I wouldn't sample a song at 44kHz stereo if the original was mono and the best quality I could get out of it was less than 10kHz. However, if it exists, I want it to be recorded. (I recently ran some tests on my ability to pick things out of the noise, and I was able to pick out a 2kHz sine wave buried 20-30dB UNDER white noise. I think around 40dB I lost track of it, or something like that.)
And since many of the older cassettes have probably degraded somewhat (although I was listening to some recently from the mid 1980s and was surprised how well they've held up sonically), what would be a good way to squeeze the best possible quality out of them? After digitizing the cassettes, the goal (I hope) is to be able to throw out the old physical tapes, and just keep the digital files as masters (of course I'll need some way to back them up for long-term (I'm hoping 70-100+ years so it'll outlast me) storage.
I haven't discussed price yet, cause I have no idea what to budget for this. So what would be a typical price range for each component that I would be looking at? I don't want to break the bank, though, for example pay $10k for something when one that's $250 would be just fine. Also getting good quality is more important than being able to record 16 tapes simultaneously at 8x speed each. Since there are hundreds if not thousands of cassettes, though, that I'd like to convert, I WOULD like to do it relatively quickly, and not have to take several months or a year or more for the project. (of course I'll need to take time to split the tracks, label them, create ID3 tags or whatever, etc.)
And, I know this is an audio forum, but I also have a bunch of VHS tapes, and my grandpa has some 8mm video tapes (I think at least hundreds), that I would like to convert to digital format to preserve them (and be able to chuck our VHS's out to save physical space). As with the audio, I'd like the masters to be losslessly encoded at maximum necessary quality. Obviously that would mean a TON of data, so what would be a good way to get a grasp on that project? And, while I'm at it with the media conversion, is there a recommended efficient way to scan dozens of albums of old photos (and if available, the negatives - I'd guess thousands if not tens of thousands of photos) taken with older film cameras of various types, and digitize them without any loss of info?
And, while I'm at it, what's a good mp3 / other format (Vorbis, WMA, ACC, whatever's good) portable media player to get that: will hold ALL the data (lossy compressed may be ok for a portable player, but needs to be transparent (at higher sample rates I typically step LAME 3.97b3 1-2 steps higher (bitrates) than the defaults (for example if 112kbps encodes 32kHz at full range, I encode at 160kbps) - haven't tested lower sample rates much yet though so I don't know where transparency is for, say, 11kHz sample rate), is built like a tank (for example can survive repeated multiple drops, etc, to hard floors while in operation, has lots of playback tweaking features, like parametric multi-band EQ, variable playback speed, variable forward/reverse scan speed, etc), and has other features, like direct line-in recording (preferably to mp3, with all the customization options that LAME has built into the player) for example? (I'm hoping to not pay more than $400-$800 for the player, although I'd be willing to add an extra hundred or so to allow for needing to buy a 500GB 7200rpm 16MB buffer 3.5" HD and putting it in the player.)
(lol... thought I was already getting long-winded, but just checked the post length and found that I'm only using 7150 characters out of an allowable 1,024,000 chars! So what WOULD someone post that's just plain text that would use all that available space per post, or does that count other things besides just plain text?
