I currently digitize vinyl working with a technics 1210, an audio-technica at-95e, and the preamps built into my native instruments traktor kontrol s4. presumably, few people here will know what an s4 is. for purposes of this thread, it should be sufficient to note that the s4 is a midi controller (roughly speaking--actually, it uses a different protocol) which includes a 4-in, 4-out audio interface with 2 phono preamps that's geared towards DJs. the audio interface in the s4 might be comparable to standalone 4-in, 4-out USB 2.0 audio interface with 2 phono preamps in the $200 range (again, it would be an audio interface geared towards DJs so it would come with very low-latency asio drivers).

i am unsatisfied with the results i'm currently getting. i record with audacity at default settings (32-bit floating point, 44.1kHz). the gain in windows' volume mixer for the channel to which the 1210 is connected to is at 100%. the peak levels i'm getting during recording are at about -12dB to -15dB. (there's no way in audacity to further boost the volume during recording.) i don't perceive the audio quality as good at all despite the fact that i'm digitizing records in mint condition. (i'm trying to digitize vinyl-only releases so buying digital is not an option. unfortunately, in the genres i listen to--certain areas of house and techno--, vinyl-only release are relatively common.) on some recordings, the kick drum sounds muffled. on most recordings, i feel noise levels are excessive.

now, i certainly don't think the preamps in my audio interface are any good. the at-95e cartridge which i recently bought for EUR 20 is entry-level, too. does anyone have suggestions as to what preamp and cartridge to buy? as for my budget: EUR 500 (~$650) is my absolute max. ideally, i'd like to spend less. so i'd be happier if i can get something reasonable for, say, EUR 300 or so.

I can't recommend a preamp. But for cartridges, "Shure's best" (M97xE) can be found for under $100 USD. This is my "refernce point". You can spend more... a lot more... but I don't see the point in chasing sound quality that will never equal a CD.

Could it be just because it's analog vinyl? Maybe the recordings (or pressings) are not as good as you expect. The recording is often the weakest link. Have you heard these records on a better system? I grew-up in the vinyl days and I was never satisfied with vinyl. I know some people like the sound of vinyl, but you simply can't get the dynamic range (and associated low-noise) that you get with digital.

i record with audacity at default settings (32-bit floating point, 44.1kHz).

The ADC in your S4 appears to be 24-bit. All audio ADCs(and DACs) are integer, so you can't actually capture in floating point. You can save-as floating point, and Audacity (and most audio editors) work at 32-bit floating-point internally no matter what format you feed-in.

That actually shouldn't be a problem (unless your ADC is noisy). It's common for pros to record at -18dB (24-bits). With 16-bits you may be loosing some resolution, but the analog noise is normally the limiting factor (for resolution & dynamic range).

(there's no way in audacity to further boost the volume during recording.)
That's pretty common. Basically, the recoding software is just a "control center", selecting the source and taking the digital-data out of the ADC, formatting it, and sending it to the hard drive. If you need to control the volume, it has to be done on the analog side of the ADC. The main concern is keeping the peaks below 0dB so that the ADC doesn't clip (distort).

Of course, you can always boost the levels digitally after recording (with Audacity). And there are some other things you can do, like EQ, noise reduction, pop-click removal, etc. I always normalize the levels, and I always do some click & pop reduction. (I haven't seen a new-pristine record in about 30 years! biggrin.gif ) I don't normally EQ, but with some older dull-sounding records, I'll boost the highs.

Or, if you plug the analog output of the S4 into your regular soundcard's line-in, you should be able to get your recording levels up. But, you'd still be using the S4 preamps. As long as your soundcard's input isn't noisy, you should be able to get a very-good recording (ignoring the noise from the vinyl and preamp that you'll be accurately recording). Although, most regular soundcards are only 16-bits.
