Thank you.
The A at the start of the cadenza on the 24/96 FLAC download and the CD
layer of the SACD is tuned to A=442.4Hz, whereas the orchestral A's
throughout the first movement are at 447.7Hz. (In each case the frequency
is that of the highest-level bin in the FFT.)
The D at the first violin entry is at 152.3Hz rather than the correct 147Hz.
I checked this with the Tuner Lite app on my phone, which indicated that
the note was sharp of D at A=440 pitch.
It isn't possible to download the file from YouTube that you posted, as it
is copy-protected, but when I have a moment, I will capture the audio
track to a recorder so I can perform FFT analysis on the first note of
the cadenza. However:
The start of the final chord of the YouTube version starts at 22:24, ie,
22.20 after the orchestral entry at the start of the movement, for a total
file playing time of 22:36.
The final chord of the FLAC version starts at 22:10, ie, 22:06 after the
orchestral entry, for a total file playing time of 22:23.
This ratio between the two timings is very close to that required to
flatten A=445Hz (as marked on the master tape box) to A=440Hz.
This suggests that the version posted to YouTube has been slowed-down
to correct the pitch.
