Re: [fluid-dev] Query regarding FluidSynth

[Tom M.]

There is no problem with your JNI code, it works absolutely fine against 
upstream recent git. However it seems that you are using VolcanoMobile's custom 
fork? This fork seems to have stripped some of fluidsynth components away. Dont 
know if that matters... anyway I cant support you any further here, sry.

[Swapnil Gupta]

Okay .. thanks for your reply. I tried running this from a JNI file in my
Java code. The JNI function is paster here: https://pastebin.com/zU29PQck.
The problem I am facing is that it keeps on running inside
*while(fluid_player_get_status(player)
== FLUID_PLAYER_PLAYING) *indefinitely. Even after waiting for around 1 -2
minutes it keeps on running inside the loop. Please let me know if you see
some issue in the code. Thanks.

Regards.
Swapnil.

It is as fast as using the fast rendering via command line. That's why this 
section is entitled  "*Fast* file renderer for *non-realtime* rendering" and 
the short description below points out that this "is the *fastest* way to 
synthesize MIDI files." :)

Re: [fluid-dev] Query regarding FluidSynth

[Swapnil Gupta]

Hi Tom,

I went over the code that you mentioned at
http://www.fluidsynth.org/api/index.html#FileRenderer and had a question
regarding this; when we are looping over while (fluid_player_get_status
(player)
== FLUID_PLAYER_PLAYING
),
does this mean that we will have to wait for the exact duration of playback
of the MIDI file before it is dumped as a file or is it a fast rendering
like through command line? Thank you.

Regards.
Swapnil.

Re: [fluid-dev] Query regarding FluidSynth

[Tom M.]

I cannot really help you to integrate fluidsynth to android. It has been 
discussed several times on the mailing list (just search the fluid-dev archive) 
but there was no real conlusion how to do it, much less a definite guide. I am 
convinced that fluidsynth can be run on android, by cross complining glib and 
then fluidsynth. But ofc it's tricky and time consuming. That's why several 
custom forks take short cuts, e.g. by getting rid of glib (like the one you 
listed) or using another build system than fluidsynth's, etc...


That's all I know

Tom,

Thanks a lot for that :). I want to use this in my android app using
JNI/NDK. Do you know of any definitive guide that helps me integrate
fluidsynth with android. I have come across a github project
https://github.com/VolcanoMobile/fluidsynth-android and it seems that I can
use this in my android app. Can anyone here here vouch for it? Thank you.

Regards.
Swapnil.

Just added example code for the file renderer:

Re: [fluid-dev] Query regarding FluidSynth

[Marcus Weseloh]

Hi Swapnil,

yes, it's possible via the API as well. Should work with something along
these lines (untested code, just for demonstration):

fluid_player_t* player;
fluid_file_renderer_t* renderer;

player = new_fluid_player(synth);
fluid_player_add(player, "/path/to/midifile.mid");

fluid_settings_setint(settings, "synth.parallel-render", 1); /* needed for
fast-render */
fluid_settings_setstr(settings, "audio.file.name", "/path/to/output.wav");

renderer = new_fluid_file_renderer (synth);

while (fluid_player_get_status(player) == FLUID_PLAYER_PLAYING) {
  if (fluid_file_renderer_process_block(renderer)  !=  FLUID_OK) {
break;
  }
}

delete_fluid_file_renderer(renderer);
delete_fluid_player(player);


Not shown is the synth and settings setup. Please see the /doc/example.c on
how to create and destroy Fluidsynth instances and settings objects.

Cheers,

This is exactly what fluidsynth does.

fluidsynth -ni -F out.wav soundfont.sf2 in.midi

Read the man page for more information.

Hi Swapnil,

Fluidsynth can do what you ask. You can use the following command line:

fluidsynth /path/to/soundfont.sf2 /path/to/midifile.mid
--fast-render=/path/to/output.wav

You can also specify the audio format with --audio-file-format if
Fluidsynth has been compiled with libsndfile support.

For more info, please have a look at the manual or the man page:

That is a different query, but just as possible. However, fluidsynth won't
help you with this endeavor to my knowledge. You'll want a soundfont
editing software such as swami or polyphone.

Fluidsynth can help you play back that wave file that you've made into a
midi definition. To create the the soundfont, you'll need a soundfont
creator (polyphone, swami, etc.). Good luck!
