Thank you.
The A at the start of the cadenza on the 24/96 FLAC download and the CD
layer of the SACD is at 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.
