Hi,
I would like to measure the latency of ALSA in “ReSpeaker 6-Mic CircularArray kit”. Preferable by using tools like “alsabat” or “alsa_delay”. Has anyone tried it?
I believe I would need to loopback the audio playback to the recording channel. But I already see a loopback done in circuit from DAC to ADC “https://files.seeedstudio.com/wiki/ReSpeaker_4-Mics_Linear_Array_Kit/img/voice_hat_acc.png”.
Any suggestions?
Thanks.
