alsabat test only complains about right channel.

BAT analysis: signal has 65536 frames at 48000 Hz, 2 channels, 2 bytes per sample.

Channel 1 - Checking for target frequency 821.00 Hz
Amplitude: 31128.9; Percentage: [95]
Detected peak at 821.04 Hz of 41.56 dB
 Total 42.4 dB from 818.85 to 823.24 Hz
 PASS: Peak detected at target frequency
Detected at least 1 signal(s) in total

Channel 2 - Checking for target frequency 821.00 Hz
Amplitude: 30990.5; Percentage: [94]
Detected peak at 815.92 Hz of 20.72 dB
 Total 20.7 dB from 815.92 to 815.92 Hz
Detected peak at 821.04 Hz of 38.11 dB
 Total 39.5 dB from 817.38 to 822.51 Hz
 PASS: Peak detected at target frequency
Detected peak at 823.97 Hz of 20.52 dB
 Total 39.5 dB from 823.97 to 823.97 Hz
 PASS: Peak detected at target frequency
Detected at least 3 signal(s) in total

Return value is -1003

Attached: ADLP_RVP_NOCODEC_alsabat_wav_captured.zip

  • bat.wav.9LAB5b ; alsabat test output
  • left.wav ; only left channel
  • right.wav ; only right channel-

Left and Right channels are separated. Did frequency analysis.
left_fa_20230223_190923
right_fa_20230223_190930

One caveat is I couldn't reproduce this manually with same device.
