Speaker calibration using a networked sound device

[DSt]

Hello,

I would like to use REW to calibrate a speaker that is driven by a networked device (see bela.io). I can send and play a wav file over this device. I can record the mic output directly into a USB soundcard on my computer (mac).

I am wondering if there exists a procedure whereby I can play a wav file - ex: a sine swept stimulus - to create a compensated transfer function of the networked sound card/speaker.

Any ideas? Please let me know if anything is unclear.

Thanks,
Dan

Need the latest V5.19 beta from the Downloads section to use the procedure.

Is this the only way that a sweep can be played over networked audio on a PC while measuring on a Umik-1 please John?

I have a USB Umik-1 to measure the audio, and the networked audio device is accessed via ASIO. Unfortunately I don't think I can configure ASIO for the output and the Umik-1 for the input in Preferences/Soundcard.

Could this be made possible please, or will I have to save the sweep as a wav and play via another media application while measuring with the Umik-1?

Many thanks.

ASIO requires inputs and outputs to be from the same device. You may be able to use ASIO4All, which creates a synthetic ASIO device using WDM drivers for multiple devices, to do what you want using ASIO drivers.
