Low latency open-source VOIP system for music
By Alexander Carot
I have run Soundjack as a one-way system for sending audio from a shortwave radio over the internet. It has worked well with Windows 7 and Mac OS 10.x. The Windows version requires an ASIO audio interface.
oggrx~ and oggtx~

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
i managed to get Robin Gareus’ externals. They are available here, though they are unmaintained.
The binaries are still online at:
http://gareus.org/d/oggZmax-v0.6-i386.zip
http://gareus.org/d/oggZmax-v0.7-rc2-i386.zip
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
Use streamout~ and streamin~ to stream audio over a local network
The ‘help file’ for streamout~ has an example. Change ‘localhost’ in the connect message to the local IP address of the target.
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.

Stream audio over the Internet using Max

Note: tested 12/2015 – from mac os el-cap working across LAN but flakey. Make sure Sample rates are matching. Latency is adjustable using buffer size in app. Your results may vary.

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:

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
<?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_USERPWD, "$USERNAME:$PASSWORD");
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);
var_dump($info);
