Too old, please test current FFmpeg git
The resulting movie will not play.

Do they define the field of view of the stereographic input (that would

Well, this is clear to me - but what size do you use? My use of the term
'window' may be unclear in this context: I meant the window size for the
fft, i.e. how many samples are used in one fft run? I take from your
code that the window size is two

Paul,
I'm working on dual fisheye output
I've tested double-fisheye input and output and found no problems. This
can also be used for tilting of 180° single-fisheye images:
set "IN=IMG_077.jpg" :: Input image or video
set "PITCH=0" :: Rotation angle around X axis
set "YA
Today, I have been experimenting with the 'showspectrum' filter, mostly
with 'showspectrumpic'.
I think there is a bug in the log scaling of the frequency axis if (and
only if) it doesn't start at zero: The ratios of the frequency axis'
labelings is not constant, they grow with larger values.

As for the filename, I used a bash variable, and it worked. I should have
thought about it earlier.
I haven't found yet how to keep the bitrate and size, and still have to add
delay for the sound.
I tried to play back the file on another machine (Windows this time), and
it doesn't work.
