<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. What would be even better if you could simply load
it into an array natively and export from it, then all the
problems this object already has would become moot.<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

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.
