I use the compand and gain effects in sox, but my target is different
from yours: movies would involve splitting and recombining the audio
and video streams.

My process converts anything that ffmpeg will play into WAV files
(CD format), which sox then concatenates and compands into another
WAV file, which lame then encodes to an MP3.

My target is to convert (possibly segue'd) classical music tracks
(potentially huge dynamic range) into something that can be listened
to on an MP3 player in noisy places like, say, the street.

The critical lines (embedded in a load of shell) are
  ffmpeg -hide_banner -y -i "$1" -ar 44100 -ac 2 "$Unique0/$Filenumber.wav"
where the $Filenumbers are 1+ sequence numbers so they collate,
  sox "$Unique0"/1*.wav -t wav -r 44100 -b 16 -c 2 "$Unique0/0.wav" compand 
0.3,1 6:-70,-60,-20 -15 -90 0.2 gain -n -0.01;
where the companding parameters are reasonably aggressive and the
normalisation is "turned up to ten", and
  lame -b "${Fixedbitrate:-128}" "$Unique0/0.wav" "$Unique0/0.mp3"
is for fairly unendowed MP3 players.

($Unique0 is just a nonce working directory.)

> or can it be done automatically, on the fly?

On the fly would mean delaying the video to match the audio, which is
necessarily delayed (by sox needing look-ahead in the audio stream).
I've thought about it over the years, but never tried it, mainly
because in the situation where it would have been most useful
(ie driving, particularly commuting alone), I didn't have any way
of intercepting the audio between tuner and amplifier. (Nowadays,
I rely on the thumb control on the steering wheel.) That's for the
radio, and occasional CD. Otherwise, the tracks on my USB stick would
usually have been companded as above.

I would be interested if someone worked out how to do splitting, sox,
and recombining reliably enough to preserve the synchronisation.
(Automatic, but not on the fly.)

Cheers,
David.

Yes, I get it. I actually thought the opposite to begin with, i.e.
the more file the better since then the computer would be able to

If you want something you can throw into a script, I recommend to look 
at melt and use its "loudness" filter.

You will want to run it in two-pass mode, so that it knows ahead the 
dynamics of each "tune" (or movie).

It can be tricky to capture the output from first pass and feed it into 
second pass (because the main use for the MLT framework is not the 
command-line tool melt but instead XML-based linkage to GUI tools).

Maybe this script is useful for inspiration:

It is going to be difficult or impossible to get good results across 
many different mp4 files by feeding them all through a command-line tool 
with the same set of options.  It might be possible to script a solution 
that uses command-line tools to analyze each file and tune the options, 
but I dunno...



The most direct path to good results would be to use an interactive 
audio editor.  Then it's up to your skills as an audio engineer.  As, 
Audacity only does audio files, the workflow would be to use a video 
tool to extract the audio tracks, rework the audio with Audacity, and 
then use a video tool to replace the old audio with the new audio.



Be sure you backup your original files before you start messing with them.

PPC64 big-endian is no longer being supported. I *think* the

https://cdimage.debian.org/mirror/cdimage/archive/8.11.0/

PPC64 little-endian is up to date.

keep pursuing Windows ...

The list of SANE: Supported Devices 
at:
http://www.sane-project.org/sane-mfgs.html#Z-CANON

Says there is good support for the CanoScan 700F but does not list support at 
all for the CanoScan LiDE 700F (but does have separate listing for several 
other models differentiated by LiDE, e.g. CanoScan 600 vs. CanoScan LiDE 600 
(I'm guessing about 10 different models like this).

I vaguely remember / suspect this is what I ran into last time I tried this.  
I will do a little more reading, I don't know what the LiDE indicates...

Indeed it is. It is a backend to SANE. The Project says that support

I forgot to put a smiley in there :-)

I can imagine that simple-scan caters more to the expectation of
a modern GUI user, and thus may be the better choice, Especially
if said user has already bought into the "desktop" paradigm.

I tried for a while and... it's not for me.

normalize audio in mp4s

[Emanuel Berg]

how can I normalize the audio in mp4 video files? both WRT not
having to lower the volume when there's a firefight and raise it
when they start talking again, _and_ WRT playing several files, e.g.
music videos, and having them have basically the same volume?

if need be, I can set volume modifications to each file, manually if
I knew how to do it. this wouldn't work for firefight/talk
movies tho.

or can it be done automatically, on the fly?

I use mpv.

Yes, it's a lib:

  libsane: /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1
  libsane: /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.0.27

Like you, my preference is xsane as a fromtend to SANE. However, I do
not think it is the lack of shinyness that puts users off using it.
Not completely, anyway. What is perceived as the plethora of options
and things to click on is a factor, particulary when it comes to new

And don't forget - Ubuntu and Mint (both widely used) ship simple-scan.

Thanks for the reply!

I don't see sane-genesys (or genesys) in Wheezy, Jessie, or Buster.  I suppose 
I'd have to compile build it myself (or try installing testing or similar) -- 
not sure I'm ready for either.

I think I'll boot the Buster system back into Windows (Vista) and see if I can 
get it to work there -- I do apparently have to find and download the Windows 
driver.

Going to take a break for a while -- probably go out and do my run.

Simple software for a scanner with ability to crop (CanoScan LIDE 700F)

[ghe]

Ok, I noticed that simple-scan uses sane / xsane, so I didn't have high
hopes (as h-node found nothing compatible), but I installed it anyway on
my Buster system -- no luck: ~"No scanner found".

You might have some luck on the web.

My scanner came with Windows and Mac software, but there aere howTos
telling how to get it going on Linux.

Simple Scan is working perfectly for me now.

The system with Buster also has Windows 8 (or Vista? -- I forget which) on it, 
I'll boot into that and see if it works there.

According to this [1] man page, the sane-genesys backend supports your
model. No first-hand experience, though...

> I'll look into simple-scan.

Simple-scan is also based on libsane (as Xsane is). It also depends
on all those "desktop goodies" as dbus-session, xdg-utils, gsettings
and friends, which you might like -- or not. So it may be called
"simple" but Xsane is definitely simpler -- although most definitely
not as shiny.

Thanks for the reply!

Yes, you're right (of course).  It must have been SANE that I tried all those 
years ago.  Someone else suggested SANE + XSANE and suggested a page where I 
could check for a driver (h-node) (or compatibility):

https://h-node.org/scanners/catalogue/en/1/1/Canon-

Just check the configuration in /etc/initramfs-tools/

but yes, if you solve this, you will most probably not have to build the
driver in the kernel

Simple software for a scanner with ability to crop (CanoScan LIDE 700F)

[rhkramer]

Is there a simple program to use a scanner (CanoScan LIDE 700F) on any of 
Wheezy, Jessie, or Buster?  It needs to have the ability to crop an image.

I dread the idea of trying to set it up in CUPS, in fact, iirc, last time I 
tried it in CUPS (which was quite a while ago (5 years? longer?)), I could not 
find a driver (either there was no driver, or maybe there was a "maybe" driver 
(a driver that might work for several different scanners, but did not work for 
me -- that was probably under Wheezy)).  (If CUPS is the only possibility, I 
probably won't even try, partly because I'm in something of a hurry.)

Background: I'm trying to do taxes for a few of my friends using H Block's 
free online software (they qualify, as all their income is due to wages).  The 
online software has the ability to automatically read (i.e., OCR) W2s from a 
picture.  It is inconvenient for me to take the pictures for various reasons 
(among them, my camera does not have an interface (USB or anything else) to 
connect to a computer, I have to take the pictures, save them to an SD card, 
then move them to the computer, and somewhere in the process, crop them so 
they have a minimal border on all sides, another is setting up the camera on a 
tripod and aimed at a suitable dark background and held flat).

The feature in the H Block software is named "Snap-a-pic W-2 capture", and 
I'm not 100% sure it will work with an image from a scanner, but it seems 
worth a try -- it would be much easier in many ways.

At least one of my friends is anxious to get her tax refund (I'm sure they all 
are, but she is most anxious).

Suggestions?

No, I'm using my own kernel and not the Debian's one, but I didn't have 
to build the firmware into the kernel image before (in the case of the 
old WiFi card and old laptop). Now after I moved in to the new laptop 
I have to, and I don't know why. 

I just checked, and it looks like the usr/lib/firmware/ dir is included 
in the stock Debian kernel's initrd image, but it's not in mine kernel's 
initrd. That's weird because I generate the images via 
*update-initramfs -u -k all* all the time. So why does one have this dir 
included and the other not? I think when I find out what's going on here

I think if the intel driver is not compiled in the kernel, you do not have
to compile the firmware.

So what you are actually saying, that when you have the stock kernel and
load the intel driver, it does not pick up the firmware?

Can you confirm this?

I'm just asking because I had a BCM WiFi card in my previous laptop and 
that card needed firmware-brcm80211 . Now I have a new laptop, and it 
has an Intel WiFi, which needs firmware-iwlwifi . I have the same setup 
(LUKSv2+LVM), and the exact same system (it was moved to the new laptop), 
and in the case of the Intel WiFi I have to compile the firmware into 
the kernel using the following kernel options:

CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
CONFIG_EXTRA_FIRMWARE="iwlwifi-6000g2a-6.ucode"

So the question I'm asking myself is why weren't the options needed in 
the case of my old WiFi card? It also wanted its firmware but it looks
like it could be loaded after the system partition was decrypted. So 
it's weird...

Specifically, the one named "Date:".

Of course, humans aren't always adept and translating local times
between different time zones in their heads while reading through
a bunch of email.  Someone who just glances at "14:24:47" and overlooks
the "+1100" part might think "Oh, it was sent at two-thirty in the
afternoon..." and not realize that two-thirty in the sender's time
zone is substantially different from two-thirty in the reader's time
zone.

Interesting -- I guess I forgot that in this discussion we have to distinguish 
between the behavior in a browser viewing the gmail page, vs. behavior in a 
"real" email client (e.g., kmail, ...)

I'm pretty sure Mick is talking about the behavior in gmail in a browser, and 
I suspect that the reason he still sees the email in "all mail" is because he 
is seeing the "sent" version (rather than a received copy) (but I'm not 
positive about that).

My policy on email is simple: I assume that everyone in the world
can read it, if they truly want to take the time and spend the resources
to do so.  If I don't want a secret to get out, I don't send it via
email.  Doesn't matter who the recipient is, what "security" arrangements
are in place, etc.

Now, that's just me, and does not reflect the policies of my workplace,

yes this is it. so people (governments, etc.) were believing they do

Mutt displays the date and time of your email as "Fri, 6 Mar 2020
