I have a problem in the acquisition of signals by the PC sound input, because the Hardware used PCM2902 DAC, there is Inter-Channel Phase Difference. according to this document:
http://www.ti.com/lit/er/slaz036a/slaz036a.pdf
And I can not synchronize the audio acquisition on the inputs. Do you have any way to do this? Thanks in advance.

E não consigo sincronizar a aquisição de áudio nas entradas. Você tem alguma maneira de fazer isso? Desde já, obrigado.
Hi rd,
according to the PDF there is a phase shift of 1 sample:
- you can "pre-shift" the waveforms before outputting them
- you can "post-shift" the acquired waveforms as needed…
Hi rd,
What component could you use to do this?
To "shift" waveforms you could either change the timestamp of the waveform or you could prepend/append samples to the waveform sample array…
I think I'm doing something wrong or not understanding what you told me right. Look what I tried to do, but it did not work:
Hi rd,
you can manipulate each waveform individually using GetWaveformComponents and/or BuildWaveform.
The function you picked will not do what you need…
