Non linear echo suppression on VF3100
Hi all, I'm currently working with VF3100. I have experienced problems (echo issues) in some conditions: for example in case of poor-quality loudspeakers or if you change the speakers volume. Among the vfctrl parameters that can be configured, I found NLATTENONOFF (disabled by default) and NLAEC_MOD...

Re: How to use DFU loader for VF3100-L33 evaluation board
In Device Manager I can see 2 USB devices: - XMOS Devices --> XMOS Microphone Array Control - Other devices --> XMOS DFU But XMOS DFU shows a yellow triangle: driver not installed. In section 5 of the Vocalfusion-Control-Users_guide you attached is written: Note that the XMOS DFU device remains unre...

Re: how extract a single mic signal from c_4x_pdm_mic_0 channel returned by mic_array_pdm_rx()
Hi, I should extract one mic signal sampled at 48 kHz (96 kHz also could be fine). What do you suggest me to do? I thought about 2 alternatives: 1) extract the 96 kHz signal after the first stage inside mic_array_decimate_to_pcm_4ch() and decimate it. This requires to change the assembler code and f...

Re: Use of buttons A-D on XK-VF3100-L33 evaluation board
Hi David,
I tried with 0 without success (on tile [0] : ...).
On the xTIME Composer I see the same error message and the application does not start.
Don't you see the same error in your setup?

Re: Use of buttons A-D on XK-VF3100-L33 evaluation board
Hi mon2,
attached a zip file with my changes to the sw_vocalfusion-[sw]_1.1.2rc5 firmware.
I added the lib_frs module and changed a few files (these are also included into the zip).
Thank you
Fabrizio

Hi all, I would like to extract a mic signal from the 4-mic streaming channel "c_4x_pdm_mic_0" outputted by mic_array_pdm_rx(). From pdm_mic.xc : mic_array_pdm_rx(p_pdm_mics, c_4x_pdm_mic_0, c_4x_pdm_mic_1); mic_array_decimate_to_pcm_4ch(c_4x_pdm_mic_0, c_ds_output[0], MIC_ARRAY_NO_INTERNA...
