I use Librosa library to calculate chroma from audio signal.

chroma = librosa.feature.chroma_stft(y=audiosignal, sr=44100, window=window, n_fft=8192, hop_length=3276)

I would like to know how to find the pitch class value in Hz? because the Librosa library return chromagram value with shape=(n_chroma, t), but I want to get "frequency" and "time" information.

Thanks.

If you want Hz, maybe you're looking for librosa.feature.stft which returns a frequency in Hz instead of a pitch class.
