Ping-pong efect with sox

Hello!

I know this can be done with DSP as I have experience before, but I don't know can Sox do it. I was driving with car and there was this DSP system which allowed to put delay to left and right. Of course when left delay increased I steered to left as my left side got further away :)

Anyway I'm thinking about using Sox to give audible error and I was thinking that is it possible synthesise PING sound and then put it somewhere in sound image between left and right. Not just with balance but also with delay to enhance the effect.

Any ideas or how to do it easily? Or if Sox is totally wrong tool for it, links to better programs are appreciated.

I'm more in to video editing than audio engineering so please be gentle.

BR,

Sox Tagging aiff Files

Does anyone know how sox tags aiff files with a comment and if it is 
possible to write other tags as well?

If not, do you know of a command line tool that can tag aiff files? 
ExifTool can read them, but can't write them. Others like id3tag and id3v2 
attempt to write them, but with an id3 header, which doesn't work for 
aiff.

Thanks,

Trevor

Heheh, I actually did search the man pages, but I was searching for the 
tag string and not comment.

Thanks. It does answer my question about how sox writes comments and it 
appears sox writes the metadata in the comment block for aiff. I was 
hoping that the default comment was an ID3 comment tag, but this isn't the 
case. So, I'm still looking for a solution to write the metadata from a 
flac file to aiff files using the ID3 block rather than the comment 
block, so they could be read in itunes. I guess I'll have to use xld or 
max or itunes2flac on the mac to do it. I was really hoping I could do it 
on the command line in linux, but I can't find any command line utilities 
that will write metadata to the ID3 block in aiff files.

Thanks,

Trevor

sox-14.3.1 / CMake / MingW / MSVS++

Hi,

I could get a libsox.lib and the other compiled programs, when I use 
CMake and MSVS++ 9 (2008) on Win. But there is no way to do it with 
CMake and MingW. Doesn't this work at all? Or has someone any idea for 
me? Is it right that there is no dynamic lib (dll) compiled?

CMake is also looking for a "ln.exe" -> LN-NOTFOUND . I found an old 
"ln.exe" (hardlinking-tool from 2003) but this is causing some problems 
compiling some programs coming with sox (which I don't need) - even with 
MSVS++. Has anyone an idea, where to get the right "ln.exe"?

Best regards
Thomas

That is what I get, compiling with MingW:

Glad to hear that confirmation about CMake.  There is also a pre-build
msvc9 project under sox-14.3.1/msvc9.

The main reason cmake support is included is for msvc support.  Right
now, the maintainer of the cmake support is a little less active in
project and our new windows expert is maintaining the msvc project.

The preferred method to compile mingw is with the configure script
(and thus needing the MSYS packages installed).  It is how sox.exe on
web site is compiled.  Patches for cmake and mingw are welcome though.

At first glance, this looks like a gcc issue.  It looks like your
using gcc 3.4.5?  I've only been compiling with gcc 4.x.x series.

Sox doesn't redefine _stati64... It does do a "#define stat _stat64"
though.  You might want to do some searching and find out were the
duplicate _stati64 is coming from.

Re: sox-14.3.1 / CMake / MingW / MSVS++

Hi,

thank you! This compiling problem may be also caused by a strange chaos 
in this MinGW "lib" and "libexec" folder...

But: No dll ...?

Any idea about LN ?

Regards
Thomas

Opps, missed that question.  Currently, no with mingw .  In theory, it
should be working though because configure/libtool have the support.
I personally only link in the static library and have not spent time
to figure out why mingw will not create them.   libtool gives
following message during link phase of libsox.dll and then reverts to
building static only (and some other warnings as well):

*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.

You might try removing "-no-undefine" from Makefile.  All optional
libraries used by libsox.dll will need to be DLL's as well if its ever
to work (such as libogg.dll, etc).

The only reason its used is to do:

ln -s sox.exe soxi.exe
ln -s sox.exe play.exe
ln -s sox.exe rec.exe

Since you can do that by hand or just skip it since you mainly want
libraries, all you need to do is find away for it to gracefully fail.
You don't really need a working ln.exe.

vol effect inverts phase acc. to man pages - how to revert that back?

Hi folks.

I just read by coincidence in the man-pages that vol reverts phase !?!? Can anybody confirm that?

How do I revert that back to original?

Or shall I better use "gain" instead? It doesn't say in the man pages that the phase is changed with "gain".

THX

Cheers
