stereo FIR in VSIDE

Post by MOUNIKA MADURI » Thu 2018-01-25 7:02

hi,
I have bought vs1063 evaluation kit.In this to record voice can we use stereoFIR example code.If we can use ,do we need to change anything in the code and do we need set any hardware for recording voice and to play back through headset.

> how can we identify voice is recording and went to codec
> can i connect mic directly to Line In jack in evaluation board

Can anyone help me ??

Is this the same project you were doing earlier? Or is this something else?

In case this is the same project you have been asking about before:
The VS10X3 StereoFIR template is not a recorder. It reads audio from VS1063's ADC (Line in or microphone in), then filters it with an FIR filter, then sends the filtered result to the DAC (earphone output). But it doesn't record the audio to a file, and it doesn't send it out digitally.

Kind regards,

Good signatures never die. They just fade away.
