• Can pyAudioAnalysis be used on a live http audio stream ?

  30 mars 2022, par Tompo

  I am trying to use pyAudioAnalysis to analyse an audio stream in real-time from a HTTP stream. My goal is to use the Zero Crossing Rate (ZCR) and other methods in this library to identify events in the stream.

  


  pyAudioAnalysis only supports input from a file but converting a http stream to a .wav will create a large overhead and temporary file management I would like to avoid.

  


  My method is as follows :

  


  Using ffmpeg I was able to get the raw audio bytes into a subprocess pipe.

  


  try:
    song = subprocess.Popen(["ffmpeg", "-i", "https://media-url/example", "-acodec", "pcm_s16le", "-ac", "1", "-f", "wav", "pipe:1"],
                            stdout=subprocess.PIPE)


  


  I then buffered this data using pyAudio with the hope of being able to use the bytes in pyAudioAnalysis

  


  CHUNK = 65536

p = pyaudio.PyAudio()

stream = p.open(format=pyaudio.paInt16,
                channels=1,
                rate=44100,
                output=True)

data = song.stdout.read(CHUNK)

while len(data) > 0:
    stream.write(data)
    data = song.stdout.read(CHUNK)


  


  However, inputting this data output into AudioBasicIO.read_audio_generic() produces an empty numpy array.

  


  Is there a valid solution to this problem without temporary file creation ?

  


• C# - Discord.Net - Trying to read audio from soundcloud and transmit it to discord

  28 mars 2022, par Bruno Braga

  I am currently working on a discord bot that is able to play a song using soundcloud.
Unfortunately, I can't seem to figure out how to get it to read from the url and stream it !
The bot it made in C#, and uses Discord.net library and ffmpeg for the audio.
Would love to hear some suggestions !

  


  These are the three functions involved :

  


  [Command("teste", RunMode = RunMode.Async)]
public async Task Play(IVoiceChannel channel = null)
{
    var audioClient = await JoinChannel(channel);
    var url = "https://soundcloud.com/campatechlive/campatech-live-feat- 
        matheus-moussa-arabian-system-vol-2-psy-trance-150-original-mix";

    var ffmpeg = new Ffmpeg(audioClient);
    await ffmpeg.SendAsync(url);
}

public async Task SendAsync(string path)
{
    using (var ffmpeg = CreateStream(path))
    using (var output = ffmpeg.StandardOutput.BaseStream)
    using (var discord = _client.CreatePCMStream(AudioApplication.Mixed))
    {
        try { await output.CopyToAsync(discord); }
        finally { await discord.FlushAsync(); }
    }
}

private Process? CreateStream(string path)
{
    return Process.Start(new ProcessStartInfo
    {
        FileName = "ffmpeg",
        Arguments = $"-hide_banner -loglevel panic -i \"{path}\" -ac 2 -f 
        s16le -ar 48000 pipe:1",
        UseShellExecute = false,
        RedirectStandardOutput = true,
    });
}


  


  I'm guessing it's something on the ffmpeg arguments, but can't kind of figure out what.

  


  I've tried a bunch of different arguments on ffmpeg, but none of them worked.
Anyone can lend me a hand ?
