why "--height 49"

[lvchigo]

• When generate pb file, we use this command:
  python freeze.py --num_classes 12 --checkpoint_path work/v1/TCResNet8Model-1.0/mfcc_40_3010_0.001_mom_l1/TCResNet8Model-30000 --output_name softmax --preprocess_method no_preprocessing --height 49 --width 40 --channels 1 TCResNet8Model --width_multiplier 1.0
• so, what mean is "--height 49"?
• MFCC extract with "--window_size_ms 40 --window_stride_ms 20"?
• But, when train/valid/test, "--window_size_ms 30 --window_stride_ms 10"
