Recording to Your PC

I use my CDJ-800s and a DJM-400 to record my mixes directly to my computer via my Soundblaster 16's line-in port.

Soundblaster 16

Audio core:
Channels 2
Sample Rate 48KHz
Digital Audio 16-bit
Polyphony 128 Voices
Ports
Line In Yes
Line Out Yes
MIC In Yes
MIDI/Joystick Yes

DJM 400

Sampling Rate 96KHz
A/D, D/A converter 24 bits
RCA master outputs

My question: Can I record higher-fidelity DJ mixes if I buy a soundcard equipped with 96Khz sample rate and 24-bit digital audio? Does that have anything to do with the quality of recording music?

Thanks.

Afraid not, no. The DJM400 doesn't have a digital output, so its internal sampling rate/resolution are irrelevant. Also, your card doesn't have a digital input. Audio will be resampled by the card from its analogue input at upto 16 bit/48kHz (dependent on software settings).

If you had a mixer with a digital output (at 24 bit/96kHz) and a soundcard with a digital in that supported at least 24 bit/96kHz then you would be able to record in better quality. However, for burning to CD the audio would still need to be downsampled to 16 bit/44.1kHz, so the only benefit you'd get would be being able to do any edits/processing while it was at a greater resolution/sample rate and only bouncing down to 16 bit/44.1kHz when this had been done, allowing you to minimise any loss of quality caused by processing.

Yeah, I didn't think so. Anyways, my mixes sound good enough...that's important. I should perhaps concentrate more on levels and of course mixing seamlessly...

You look like American Psycho Christian Bale.

By the way, I should probably upgrade to a better soundcard anyways to hear music in fuller fidelity, right?

If you've got the money then go for it. The old Creatives are very dated now - for the money you can't beat an M-Audio Audiophile 2496
