been using astra to transcribe music, then to review the spectrogram to do error correction and then review the music theory resulting in very robust transcriptions for me to learn...
>The spectrogram shows a few clear problems: some wide vibrato became extra chromatic notes, and around 3:22 the tracker briefly jumped to a lower piano note while the clarinet continued above it. I’m correcting those and simplifying isolated sixteenth rests. The quiet ending is still ambiguous.
