Write with a look for timestamps

hello

i'm using SOX to generate a spectrogram from a wave file with the command :

Code:
#sox file.wav -n spectrogram

is there a way to create a spectrogram using the same command but reading file timestamps instead of the namefile.wav , since name is changing every 4 hours? (it's saved with cron at /direxample/test-$(date -v +\%H\%M).wav

Thanks for help!

Regards
