Or audio card and software. 12 bit scopes cannot verify 16bit audio, not to mention 24bit, except for large distortions... From what I can see all you need is 4 ch, even for digital. No need for MSO. MSO is really useful when you NEED 20 channels. Avoid HDO924. Horribly designed device. Stick with HDO800 or Siglent SDS800 HD(my choice). --- End quote --- I think you need both a Oscilloscope and an audio interface (Scarlett are measurement grade as I recall). Since you will be working with more than just the audio signals. And a 12 bit scope with ERES might do 15 bit resolution, which is IMHO plenty for generic audio debugging stuff. Audio is not necessarily mean sound cards, could be a spatial audio microphone system, noise cancellation or a dozen other applications which dont need high fidelity. Once I was working with door access control stuff, and 16KHz 8 bit was "Wow this sounds soo much better". --- End quote --- Yes, some of our products use Scarlett as the audio interface. We're into speech recognition, diarization and so on. 16 kHz 16 bit for incoming/outgoing audio and the internal processing is done on 32 bit..16 bit might sound a lot but if you apply some math the quantization gets ugly quickly. I think could start with a DHO814 and then see how it goes from there..? |
