I'm sorry but I am not worthy to make your acquaintance.

I'm having a pretty good week, to be honest. Looks possible I'll
be credited for testing some code to enable SteelSeries SRW-S1
racing wheels in future Linux kernels - and now I find you've
kindly written something for me. And it works.

Yes. No complaints, but I already have libsndfile and co, so all
dependencies were met. Plot produced an output channel in qjackctl
and it plays.

Instantly. I can use it so naturally, by mouse, that I want for
nothing more, except -

The other channel output (of course). Lower view area to track play,
although the way I can just move up to the upper section and quickly
get the play head in view again - is fine really. I'm quite surprised
there's so much detail from the chunk file. It's just enough for the
entire file view, but a little more would be good in the lower section.
Or maybe closer inspection of an area could be a secondary feature.
Perhaps only when 'superzoom' is engaged a more detailed visualisation
is derived from the area around the current play head position.

Reduce did one of my 1.3GB files in about 3 seconds with a resulting
size of about 1.3MB.

They are very clear. Thank you.

I don't see any high CPU while playing. Far from it in fact,
compared to similar display in Wine, although I think that
may have been more to do with how Wine does sound...

23% kwin and 14% Xorg if I drag plot's window around my
desktop frantically while playing (as a reference point).
6% and 4% respectively playing normally. Xorg drops to 5%
when plot is stopped. (i5 CPU). All by 'top' so not accurate.

All my files are 48k so Jack is set for that.

Famous names really. So many fine libs...

Everything is there. Status bar area info is good and resize-ability
isn't essential, although, if possible a scale option for the whole
main window is a must for a generally available fixed size program
window. It's all too small for squintless operation (for me) as is.
My 'monitor' is a 32" Tv at 1920x1080 at 96dpi (forced).

Of course. 64b here too. Maybe a fellow with 32b could test?

Thanks a million for this Cédric, and I hope you can find the
time to carry on with it a bit. I think it could develop into
something which very many people could find useful.

With both output channels working I'm sure it'll be my default
wav player...

Sincerely,
John.
