In Python one would write:
file_name = 'fdsafdsafds.wav'
audio, sample_rate = librosa.load(file_name, res_type='kaiser_fast')
mfccs = librosa.feature.mfcc(y=audio, sr=sample_rate, n_mfcc=40)
Is there such a library or the one with this functionality in other, compiled languages? in C++, Go, Rust, .NET.... I haven't found any
You could use kaldi: https://kaldi-asr.org/doc/compute-mfcc-feats_8cc.html
