Your metro.mat file doesn't contain anything.

There is nothing to plot, although sensorlog_20231201_123144.m4a could have something if you want to share it.

The problem with your data is that you have not collected any measured data or saved in it.
A = load('metro.mat')
A = struct with fields:
AudioInfo: [1×1 struct]
A.AudioInfo
ans = struct with fields:
Filename: 'sensorlog_20231201_123144.m4a' CompressionMethod: 'AAC' NumChannels: 2 SampleRate: 44100 TotalSamples: 2511768 Duration: 56.9562 Title: [] Comment: [] Artist: [] BitRate: 96
