record audio on XK-AUDIO-216-MC-AB into .wav file

[Andrew_SanJose]

Hi,
I am trying to record music and manually playback it under the control of button on XK-AUDIO-216-MC-AB. According to AN00162 example, the audio can be loopbacked on XK-AUDIO-216-MC-AB. So can we record audio and then persistently store the data on board or transfer it to USB device, into .wave file?

Regards,
Andrew

i guess it should be possible to save audio onto an via SPI attached SD card as an example.
passing a wav file through usb directly is not possible.
its gonna be raw audio as soundccard -> then save/record on host device
or even persist on storage(sd) and then enumerate as usb storage, but dont really know if this has been done with xmos before.
