• How to accurately detect the start of the main beat and soundtracks in diverse audio tracks ?

  18 juin 2024, par SnoofFloof

  I'm working on a project where I need to edit soundtracks. The challenge is to detect when the main beat and melody of any given soundtrack is properly developed. I am certain there is better terminology to describe what I am aiming for, but ideally, I want to skip the "build-up" and immediately have the song starting at the "main part". This needs to work for various songs across different genres, which often have different structures and onset patterns, making it difficult to streamline the process.

  


  For example :

  


  https://www.youtube.com/watch?v=P77CNtHrnmI -> I would want to my code to identify the onset at 0:24

  


  https://www.youtube.com/watch?v=OOsPCR8SyRo -> Onset detection at 0:12

  


  https://www.youtube.com/watch?v=XKiZBlelIzc -> Onset detection at 0:19

  


  I've tried using librosa to analyze the onset strength and detect beats, but the current implementation either detects the very beginning of the song or fails to consistently identify when the beat is fully developed.

  


  This was my approach ;

  


  def analyze_and_edit_audio(input_file, output_file):
    y, sr = librosa.load(input_file)
    tempo, beat_frames = librosa.beat.beat_track(y=y, sr=sr)
    beat_times = librosa.frames_to_time(beat_frames, sr=sr)
    main_beat_start = beat_times[0]


  


  I have very little experience with librosa/audio editing, so I would appreciate any suggestions you might have !

  


• Distube (Unbuntu) - DiscordAPIERROR : Invalid Form Body Content : Must be 2000 or fewer in length

  25 mai 2021, par Bombo43453

  I recently transferred my discord bot to a VPS that is unbuntu based. The issue is that it will not play any sort of music. It starts to process it and then it says the error below.

  


  (node:5252) UnhandledPromiseRejectionWarning: DiscordAPIError: Invalid Form Body

  My Play.js File :

  


  module.exports = {
    name: `play`,
    description: `Play A Song`,
    hidden: false,
    aliases: [`p`],
    usage: `(song)`,

async execute(client, message, args, Discord, errorlog, botlog, msglog, profileData, guildProfile){
    const music = args.join(' ');
    if (!message.member.voice.channel) return message.channel.send(`Uh Oh - You're not in a voice channel !`);

        if (message.guild.me.voice.channel && message.member.voice.channel.id !== message.guild.me.voice.channel.id) return message.channel.send(` You Are Not In The Same Voice Channel The Bot Is Currently In!`);

        if (!args[0]) return message.channel.send(`Uh Oh - Please indicate the title of a song !`);
    client.distube.play(message, args.join(' '))
}
}


  


  I can confirm that this works when I use windows powershell. Do you think this can possibly be due to it being unbuntu or does distube have no support for this ?

  


• Mp3 file not showing in any media player after creating through ffmpeg

  4 mai 2019, par Aashit Shah

  Mp3 file not showing in any application after the mp3 file is saved . After 15 odd minutes it is automatically shown . if i manually change the name from file manager it will be instantly shown . How to solve this problem .

  Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
  
              String[] projection = {
  
                      MediaStore.Audio.Media.TITLE,
  
                      MediaStore.Audio.Media.DATA,
  
                      MediaStore.Audio.Media.DISPLAY_NAME,
  
                      MediaStore.Audio.Media.DURATION,
  
                      MediaStore.Audio.Media.ALBUM_ID
  
              };
  
              String sortOrder =  MediaStore.Audio.Media.DISPLAY_NAME
  
              Cursor c = getContentResolver().query(uri,projection,null,null,sortOrder);
  
              if(c.moveToFirst())
  
              {
  
                  do {
  
                      String title = c.getString(c.getColumnIndex(MediaStore.Audio.Media.TITLE));
  
                      String data = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DATA));
  
                      String name = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
  
                      String duration = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DURATION));
  
                      String albumid= c.getString(c.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
  
                      Songs song = new Songs(title,data,name,duration,albumid);
  
                      songs.add(song);
  
                      title1.add(name);
  
                  }while (c.moveToNext());
  
              }

  Output file path :

   Environment.getExternalStorageDirectory()+ "/Trim"+".mp3";

  This is my command :

  "-y","-ss", start,"-i", input_path,"-t", end,"-metadata","title=Trim","-acodec", "copy","-preset", "ultrafast",output_path
