Is there a spectrum analyzer (mp3/wav) -> (txt/csv)?

Question

linux

Is there a simple command line utility, or sources that allow you to take an audio file as input and output the signal spectrum in text form at the output.
There are a bunch of programs that export beautiful spectrum graphs to png. But I need exactly the text format for machine analysis later.
If who met similar utilities share please.
