we are using the respeaker v2.0 4 mic array for an audio tracking project and were wondering if there is a way to disable the voice processing entirely so as not to filter out other noise. Do any of the firmware binaries work well for this, or are there other parameters that can be set to ‘off’ to accomplish this?
|1_channel_firmware.bin||1||processed audio for ASR|
|6_channels_firmware.bin||6||channel 0: processed audio for ASR, channel 1-4: 4 microphones' raw data, channel 5: playback|
|6_channels_firmware_6.02dB.bin||6||same as 6_channels_firmware.bin, but 4 microphones have a 6.02dB gain|
|6_channels_firmware_12.04dB.bin||6||same as 6_channels_firmware.bin, but 4 microphones have a 12.04dB gain|
|48k_1_channels_firmware.bin||1||48k sample rate, 1 input channel|
|48k_6_channels_firmware_6.02dB.bin||6||s48k sample rate, 1 input channel, 6.02dB gain|
