I need to see (as with eyes) about 1-second worth of audio sampled at 8KHz (16-bit PCM if that matters). The object is a single 1-second frame, with distinguishable boundary characteristics. There are multiple frames, all a bit different, it's fine if I can see a randomly (approximately) chosen one.
So far I used Excel to plot the samples, but it is painfully slow manual process (dump samples, import in Excel, plot.)
I was wondering can I use Rigol to capture the analog audio and 'see' it.
I am not a scope expert, so questions that come to mind are:
- general settings for this frequency range
- triggering - manual is OK, but then I'd need 2-3 seconds worth of samples to spot a full frame.
All feedback welcome!
