Re: editing & combining sound files?

[Nicolas Cueto via use-livecode]

Well, maybe some day I'll put the time in to study Geoff's and Tom's
solutions. But, for future reference, below is my easier-for-me solution.

First, use a sound-editor (Goldwave) to convert all AU files to RAW (i.e.,
snd).

Second, run this LC script to merge those converted files (interleaved with
silence) into a new .snd file:

 put URL "binfile:C:/the_path/faster/{file ID}.snd" into tNewSnd
 put URL "binfile:C:/the_path/1_sec_silence.snd" after tNewSnd
 put URL "binfile:C:/the_path/slow/{file ID}.snd" after tNewSnd
 put tNewSnd into URL  "binfile:C:/the_path/CD/{file ID}.snd"

Third, use the sound-editor again, this time to convert those new .snd
files into .mp3.

That's it. But if someone wants to post exact details of how to LC script
what Geoff suggests, i.e., stripping headers from an .au (or any!) sound
file type, I'm still all ears.

Cheers.

Have you looked at the performance of using styledText?

put the styledText of fld "audioList" into tTextA
repeat for each key tKey in tTextA
put pColor into tTextA[tKey]["style"]["backgroundcolor"]
end repeat
set the styledText of fld "audioList" to tTextA

Thanks,

Re: editing & combining sound files?

[Geoff Canyon via use-livecode]

I did something very much like this way, way, way long ago (in the MetaCard
days...). I don't remember the sound format, and it was mono, not stereo,
but it turned out that the format for the sound file was *really* simple: a
few bytes of easily-managed header, a bunch of binary data that represented
the sound file data, and a few bytes of footer.

So the steps above would be roughly:

1. Read in the binary data from the sound file, strip the header/footer.
2. Figure out what the "silence" value is for that sound format, append a
certain number of that value to the data.
3,4. Read in the binary data from the second file, strip the header/footer
and append to the data.
5. ??? Not sure how to do this. Instead, might add the appropriate
header/footer and write out the data in the same format as the input files.
6. Close the access to the original files.

If MP3 isn't comprehensible, then you could bulk convert the resulting
files from AU to MP3 using any number of tools.

editing & combining sound files?

[Nicolas Cueto via use-livecode]

Hello List,

I wish to automate a repetitive (and tedious!) process that's now being
done manually using a sound-file editor (Goldwave).

The process is:

1. Open an AU sound file.
2. Append 1 second of silence to that file.
3. Open a 2nd AU sound file.
4. Copy and append that 2nd file to the 1st file.
5. Save as MP3 with a new title that now-modified 1st file.
6. Close that 1st file unmodified.
7. [Repeat 1-6.]

If this is possible (easily possible!) with LC, what LC commands ought I be
studying/using?

Many thanks.

Thanks! (Noting: particular use, and methods used.) Optimizing LCS is 
extremely important, and methods that are great for testing items and 
arrays themselves may not be the fastest methods for real applications. 
I'm always glad to help people achieve better results, so let me know if 
you ever need a hand for your purpose.


But ( again :) ) my greater interest in this thread was, and remains, 
seeing the LC engine further optimized! That would really pay off.


Richard:

No, but it's a very good pursuit. I would expect some interesting 
results with JS. I won't have time to test these myself for a while but 
I'll remain interested.

Re: revNavigator - Cloning a card - am i doing something wrong?

[Geoff Canyon via use-livecode]

Okay, I've updated Navigator so that I think it will fix this. You (and
others with multiple monitors) will be the judge, but now on multiple
screens, when collapsing Navigator it should collapse to the top of the
screen it's on. Collapsing all Navigators should have them each collapse on
the screen they're on, only stacking with each other on that screen.

Here's hoping anyway...

Get Navigator here
. Or grab it
from GitHub .

This will resize the stack the same way as your "adapt" handler does, so 
you can eliminate that entirely:

  set the fullscreenmode of stack "ipad" to "exactFit"

I’ve made a test stack. It’s an « iPad » stack. Test it with iOS simulator on

https://www.dropbox.com/s/iwwm2syiqzqamtg/testsubstack2.livecode?dl=0

Click on « get the rect » and click on « Adapt » to set the rect of the 
background to the rect of the screen


I played with this for a while. I changed the opencard handler to a 
preOpenCard, which is when FSM is usually set. But there's something odd 
going on. When I tap the "get rect" button it says:


Rect of this stack: 170,172,938,1196
Rect of this cd: 0,0,768,1024
Screenrect: 0,0,320,480

If I use "exactfit" instead of "showAll" it does sort of work and is an 
easier way to get what you scripted. Since your app is targeted only for 
iPad, exactFit may be one of the few times it's appropriate. That said, 
it still isn't resizing to the screen even with "exactFit", and it 
should. Using "NoBorder" also gives the same results where it shouldn't.


I was able to repro your scripted solution by setting fullscreenMode to 
"noBorder" and simplifying the "adapt" script this way:


on adaptrect
  put the height of this cd into tHt
  put the width of this cd into tWd
  set the rect of this stack to 0,0,tWd,tHt -- doesn't really do that
  set the rect of grc "bkg" to 0,0,tWd,tHt
  put "Rect of bg = real rect :" & the rect of grc "bkg"  after fld "datas"
  set the top of grc "lineTop" to 0
  set the bottom of grc "lineBottom" to tHt
end adaptrect

But the stack should still fill the screen and it doesn't. Either I'm 
missing something or there's a problem with FSM.


Tested in LC 9.0.1 rc1, as it's the only version I have a compatible 
XCode for. I wonder if it's different in LC 8.x.

Hi Curry,

The stack can be found here:

In my particular use of arrays and lists, I find the lists to be a little more

Brian,

Thanks for running all these tests.

On the same topic, I'd like to mention that I use "intersect" with
arrays a lot in some scripts (for complex requests it is sometimes
faster to load raw data from mySQL and process it with arrays),
and "intersect" is really fast in LC9...

Re: revNavigator - Cloning a card - am i doing something wrong?

[Bob Sneidar via use-livecode]

I verified that if run from a script, the card will clone in the stack the 
script is running in. Otherwise it will clone in the stack the source card is 
in regardless of the topStack. Odd implementation if you ask me. I often need 
to create a new substack, then clone a card from another substack to save a lot 
of time copy pasting objects. Heretofore I've been unable to do that, but now I 
know, just place a button on card 1 of the new stack.

Re: Socket questions

[Douglas Ruisaard via use-livecode]

?Dave or Doug? ... anyway.  It sounds like a "known" problem then I tried 
searching the QC listing at Livecode's (http://quality.livecode.com/) but can't 
find any reference to that specific function and too much when looking for 
"socket" and "domain".  Do you know if a bug submission has been made for this 
issue?  You make it sound as if LC is aware of it.

Re: [ANN] DGH 2.5.1 is released

[Matthias Rebbe via use-livecode]

I second that. As an addition:  Zryip`s response time for support requests and 
bugfixes is awesome.

[ANN] Release 9.0.1 RC-2

[panagiotis merakos via use-livecode]

Dear list members,

We are pleased to announce the release of LiveCode 9.0.1 RC-2.


Getting the Release
===
You can get the release at https://downloads.livecode.com/livecode/ or via
the automatic updater.


Release Contents

LiveCode 9.0.1 RC-2 comes with 7 bugfixes, including:

21396 [iOS 12 beta] App crashes on startup
21496 Emscripten: startup script no longer runs
21417 Inclusion of tsNet causes HTML5 standalone to crash
21443 Mobile scroller on Android does not initially work
21434 visual effect not showing on android

Moreover, Android 6.0 (API 23) Marshmallow introduced a new permissions
model that lets apps request permissions from the user at runtime, rather
than prior to installation. Apps built with LC 9.0.1 do support this new
permissions model, and request permissions automatically when the app
actually requires the services or data protected by the services.

For example, if the app calls mobilePickPhoto "camera" , a dialog will be
shown to the user asking for permission to access the device camera.
If the user does not grant permission, the call will fail.

Moreover, the app can use the function
 to check if the permission for
permissionName has been granted, and the command  to explicitly ask for permissionName. For more details and
examples see the Dictionary.

Notes:
- Existing apps will continue to work without needing any changes, as
backwards compatibility has been ensured.
- You have to make sure that you check the required permissions for your
app in the standalone settings.
- Apps that run on devices running Android 6+ will work with the new
permissions model. Apps that run on older devices (less than Android 6)
will continue to work with the old permissions model.
- If the user does not grant a permission when the dialog appears for the
first time, they can change this preference from the Settings app.

Known issues


- The use of the Browser widget is not supported on Ubuntu 18.04 64 bit LTS
yet.

The full release notes are available from:
