Question

I have got one midi file and i want to play that file on web page, currently i am using midi.js player for playing but it is not working on mobile browsers.

Please guide me how to play that file or else how can i play midi or convert it into mp3

Here is my code

  $data = fopen ($midi, 'rb');
 $size= filesize($midi);
 $contents = fread ($data, $size);
 fclose($data);
 $encoded= base64_encode($contents);

 $encode = "'data:audio/midi;base64,".$encoded."=='";

and finally passing base64 value to midi.js

No correct solution

OTHER TIPS

Guessing you're on a linux machine... The simplest way is to play it with timidity and pipe the output ffmpeg:

timidity song.mid -Ow -o - | ffmpeg -i - -acodec libmp3lame -ab 64k song.mp3

If you're using Linux, use avconv instead of ffmpeg because ffmpeg is being deprecated:

timidity input.midi -Ow -o - | avconv -i - -acodec libmp3lame -b 64k output.mp3

Or lame:

timidity -Ow -o - input.midi | lame - output.mp3

I ran into a similar issue with MIDI.js not working in a mobile browser. It turned out that I had included the ogg files but was missing the mp3s (for some reason the MIDI.js only provides ogg versions of synth_drum).

FluidSynth + FFmpeg

An alternative to timidity:

sudo apt install fluidsynth ffmpeg
fluidsynth -a alsa -T raw -F - /usr/share/sounds/sf2/FluidR3_GM.sf2 MIDI_sample.mid |
  ffmpeg -f s32le -i - MIDI_sample.mp3

Tested on Ubuntu 20.04, FluidSynth 2.1.1-2, and this MIDI file: https://en.wikipedia.org/wiki/File:MIDI_sample.mid

This worked for me:

timidity my_midi_file.mid -Ow -o - | lame - -b 64 my_converted_midi.mp3

running on ubuntu 18.04

First install the Timidity package, In Ubuntu just run:

sudo apt-get install -y timidity

Then run this command:

timidity input.mid -Ow -o out.mp3

You can change the format to WAV or other formats too.
