Audio streaming object in Max

oggrx~ and oggtx~

by Robin Gareus

At Cycling 74 forum: https://cycling74.com/forums/topic/streaming-internet-radio-in-maxmsp/


I was able to receive mp3 files from a server in Max 6.18. using oggrx~. There doesn’t appear to be transport control – so this would need to be built in for synchronization.

Unexpected find: The external uses “secret rabbit code” for resampling. So it works in Max. And we have the source code but not the i386 libs that were used to compile it.

There is no binary for v.7 of oggrx~.mxo, but there is one for v.6

Original c74 post by umma08:

i managed to get Robin Gareus’ externals. They are available here, though they are unmaintained.

The binaries are still online at:



It’s been more than 3 years (OSX 10.5) since I last looked at it, it
should still work, but I don’t know. Please let me know if you encounter
any problems, so that I can warn others.

I don’t maintain this external anymore. I neither have a MAX/MSP
license, nor do I own any Apple devices. On the upside, complete
source-code is available from


Web video streaming in Max

Stream realtime video from a web browser into Max or any program that uses Syphon.

CefWithSyphon (developed by Vibeke Bertelsen) launches a web browser and Syphon server. The Max patch operates a Syphon client that receives a video stream from the server and makes it available to Jitter objects.



folder: web-video-streaming

patch: jit.gl.syphonclient.maxhelp

  • jit.gl.syphonclient.mxo:

Note: externals are included with max-projects but can also be downloaded here: http://syphon.v002.info

other dependencies (app) 
  • CefWithSyphon.app

Download the CefWIthSyphon app from here:  https://github.com/vibber/CefWithSyphon – A Mac OS binary is available and has been tested with Mac OS 10.9.2

  • Open the client example /jit.gl.syphonclient.maxhelp in  Max
  • Run the CefWithSyphon app. It will launch a browser
  • The browser content should now stream to the clientcontext window in Max 
  • If not streaming, click the “getavailableservers” message and select the correct server/client from menu objects outlined in red


Twitter streaming API

from https://dev.twitter.com/docs/streaming-apis

This diagram shows the process of handling a stream, using a data store as an intermediary.

The JSON response breaks out various components of the tweet like hashtags and URL’s but it doesn’t provide a clean version of the text – which for example could be converted to speech.

Here’s a sample response which shows all the fields:

Twitter streaming php decoder breaks out individual tweets

This code was adapted (i.e. stolen verbatim) from a stackoverflow post by drew010


Here’s the code. It solves a huge problem for the class of projects which need to grab a large amount of tweets in real time to either save in a database, or trigger some action.

My version of the code is in tkzic/api/twitterStream1.php


$USERNAME = 'youruser';
$PASSWORD = 'yourpass';
$QUERY    = 'nike';

 * Called every time a chunk of data is read, this will be a json encoded message
 * @param resource $handle The curl handle
 * @param string   $data   The data chunk (json message)
function writeCallback($handle, $data)
    echo "-----------------------------------------------------------\n";
    echo $data;
    echo "-----------------------------------------------------------\n";

    $json = json_decode($data);
    if (isset($json->user) && isset($json->text)) {
        echo "@{$json->user->screen_name}: {$json->text}\n\n";

    return strlen($data);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://stream.twitter.com/1/statuses/filter.json?track=' . urlencode($QUERY));
curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'writeCallback');
curl_setopt($ch, CURLOPT_TIMEOUT, 20); // disconnect after 20 seconds for testing
curl_setopt($ch, CURLOPT_VERBOSE, 1);  // debugging
curl_setopt($ch, CURLOPT_ENCODING,  'gzip, deflate'); // req'd to get gzip
curl_setopt($ch, CURLOPT_USERAGENT, 'tstreamer/1.0'); // req'd to get gzip

curl_exec($ch); // commence streaming

$info = curl_getinfo($ch);
