Supposing the latter might be feasible, I'd recommend you to download the latest drivers for the ALC269 from either Realtek or Acer websites and check whether you can somehow have access to a line input interface on your OS audio control panel. If the notebook itself does not have access to separate inputs for both signals, since you only mentioned that a microphone input jack is available (along with a line output one), there are still two possibilities:ġ) The manufacturer just ignored the line input interface, leaving it unconnected Ģ) The manufacturer implemented some sort of 'input multiplexing' scheme which allows the user to select the type of output by software and, hence, route the signal to the proper ALC269 chip input. More importantly, the ALC269 should also have access to microphone and line inputs, and the 'right' way to capture vinyl recordings should be with the latter interface, since its input impedance was made to match typical loading for applications such as vinyl archiving coming from a RIAA preamplifier's output signal. For vinyl capture, SNR is not that meaningful for bass, midrange and lower treble because vinyl itself has much higher noise floor than the sound board however, for upper treble, this can be relevant. The subpar SNR definitely requires a lot more care on optimal recording volume setting, so as to take as much advantage of the ADC headroom whilst avoiding clipping. The signal-to-noise ratio, however, is subpar despite these features: -98dB only, which is roughly equivalent to a standard 16-bit/44.1kHz CD (rated with a -96dB SNR). Your notebook has a Realtek ALC269 audio chip, which is a very entry-level interface.Īccording to its datasheet, available at this link, it should have a decent ADC, with support to what I'd deem good enough for a serious vinyl capture: 24-bit resolution and a sampling rate of 96kHz sampling rate.
