<p>Based on the help file this object needs a lot of love to be
truly usable. See the transposing part on anything other than the
3 apparently hardcoded sampling rates...</p>
<p>That said, it would be great to be able to support mp3 file
manipulation.<br>

What means that?

Well, translation from a poor French man speaking poor English
(LOL):
<br>
What I meant is that if you are not a guy who builds
patchs/subpatchs using available objects but only a one who is
using a ready-to-go project (assembly of patchs) built by someone
else, you will never do what have been suggested. Not everybody is
a developer-programmer, even I. So, what about a standard user of
Purr Data / Pd Vanilla!

I just checked [mp3play~] with 'iemlib' r.1.17 properly
installed and
<br>
declared under Pd Vanilla v.0.50.2 and it's the same bad
behavior than
<br>
under Purr Data v.2.13.0. Even more, here 'mp3play~-help.pd'
is not

present at all.

Do you know where the source code is for the version of mp3play~
<br>
available through Vanilla?
<br>
</blockquote>
As I wrote it, it's not available under Pd Vanilla 0.5.2 / iemlib
1.17 but only under Purr Data, as far as my little experience.
<br>
I attach to this email what I guess could be the main source file
(mp3play~.c), but with no guarantee at all, awa its help file
(mp3play~-help.pd).
<br>
This 'C' file seems to have been tested/working only on: 'debugged
for windows 013-03-2003' (line 13 of the file).
<br>
These 2 files and few others can be found on your Git repository
at: '/purr-data/externals/iemlib/iem_mp3/' (accordingly to the
copy I have on my GNU/Linux PC).

<blockquote type="cite">Hello Folks,
<br>
<br>
I'm looking for some advises regarding Recording and
Playing MP3 files -directly- inside Purr Data v2.13.0+
under GNU/Linux and Windows.
<br>
<br>
In my MIDI/Audio projects under Purr Data I'm already
using successfully:
<br>
- [oggwrite~] / [oggread~] for .ogg (Vorbis) files (with
lossy audio compression), and
<br>
- [writesf~] / [readsf~] for .wav, .aif, .au and .snd
files (with uncompressed linear pulse-code modulation).
<br>
<br>
But some users are requesting, among other demands, the
possibility to handle also MP3 (with lossy
data-compression) for extending the number of compatible
Audio equipment (like TVs) able to read them.
<br>
<br>
After analysis I found only 2 objects -not tested yet-
from the 'unauthorized' library being able to deal with
MP3:
<br>
- [mp3write~] an MP3 file recorder v.0.4, and
<br>
- [mp3cast~] an MP3 streamer v.0.5.
<br>
But there is nothing about an MP3 file reader/player.
<br>
<br>
Despite the many libraries installed by default, Purr Data
could not create any of the following objects (see towards
the end of the link - FR):
<br>
- [mp3amp~],
<br>
- [graphic-mp3amp~],
<br>
- [mp3live~],
<br>
- [mp3streamout~],
<br>
- [mp3streamin~],
<br>
- [mp3fileout~], and
<br>
- [mp3play~] from 'iemlib library'.
<br>
<br>
* [mp3play~] should be in the 'iemlib' library but it's
not there when its help file is well present in
'/opt/purr-data/lib/pd-l2ork/extra/iemlib/mp3play~-help.pd'.
<br>
One strange thing is that the 'mp3play~.c' file is well
present on the Git copy I made from Jonathan's repo for my
French translations in:
<br>
-
'/home/joe/GitLab/purr-data/externals/build/src/mp3play~.c'
(47 bytes), and
<br>
-
'/home/joe/GitLab/purr-data/externals/iemlib/iem_mp3/src/'
(107 kB).
<br>
</blockquote>
mp3play~ is not currently getting built (and wasn't in
Pd-extended, either).
<br>
<br>
What a weirdo class structure! After compiling it, you must
first create this:
<br>
<br>
[iem_mp3]
<br>
<br>
Which will then go in and trigger the setup routine for
mp3play~, so
<br>
that you can then do this:
<br>
<br>
[mp3play~]
<br>
<br>
Both will create properly. I was able to play the test file
and it
<br>
seemed to output something, though couldn't get my
headphones to work
<br>
so I don't know if it sounded right.
<br>
<br>
It appears there are no dependencies for this object, so if
we add it
<br>
then it will work in the web app, too!
<br>
<br>
I guess the first thing to do is look in Pd Vanilla and see
if anyone
<br>
has done work on this object since 2003.
