Today I’m attempting to update audiograph to run under the current iOS/xcode releases. Here are some helpful solutions to resolving compilation errors and warnings…
(update) Had problems with git, because I forgot to pull the changes from Michael Tyson, down from github before I made changes to the files locally and committed them.
Ended up doing a wholesale copy and a lot of duplicated effort – anyway it seems to work now.
Very important: The current local version of audiograph is in tkzic/coreaudio/audiograph
I have also submitted a new version 1.1 to app store. but its in the same folder I just mentioned.
runtime view controller error:
<code>'A view can only be associated with at most one view controller at a time!</code>
The only really required thing to do is to add a launch image named “[email protected]” to the app resources, and in general case (if you’re lucky enough) the app will work correctly.
In case the app does not handle touch events, then make sure that the key window has the proper size. The workaround is to set the proper frame:
This program is broken on Mac OS Monterey. The PHP code is throwing errors in the OSC library. I’m not certain there is a reasonable workaround at this point and will be looking at replacing the php code with node.js or another more reliable platform. Also, as noted below – php is no longer installed in Mac os – so it requires homebrew or macports
features
Twitter streaming v1.1 API and Twitter Apps (using http requests and Oauth in php)
lat/lon conversion and map plotting in Max
sending data to Max using OSC in php
‘speaking’ tweets using several voices (text to speech)
Using geo-coordinates to control an FM synthesizer
Converting Tweet text to Morse code
Using a data recorder to replay/save data streams (Max lists)
Compare to satellite photo of earth – note the pattern of lights.
When you get to step 5 – in the instructions – instead of writing your own code, just use a text editor to copy your access tokens into this php program which is provided:
ctwitter_max3.php
Replace the strings in this line of code by copying and pasting the appropriate ones from your Twitter application:
2. in a terminal window run the php program: ctwitter_max3.php. [note] it runs forever. Press <ctrl-c> when you want to stop streaming Tweets.
php ./ctwitter_max3.php
3. Switch back to world3.maxpat to see dots populating the map
4. In Max, press the speaker icon (lower left) to turn on audio.
5. Activate voice synth/morse code using the blue toggle (lower left)
6. Clear the map by pressing the blue message box: “clear, drawpict a 0 0”
7. Stop the Tweet stream by pressing <ctrl-c> in the terminal window
special voice fx
If you have Soundflower installed, the Mac OS speech synth output can be routed back to Max for audio processing. This is somewhat complicated, but shows how to process audio in Max from other sources.
In MacOS System Preferences, set audio output device to Soundflower 2ch
Turn up hardware volume control on your computer
In Max, Options | Audio Status, set input device to Soundflower 2ch
In world3.maxpat double click on [p audio engine] (lower left). Then in the audio-engine sub-patch activate the toggle, (lower right) for voice-fx
data recording
The built-in data recorder/playback is on the left side of world3.maxpat:
toggle ‘record’ (red toggle) to start or stop data recording
Note that data will only be recorded when the php program is streaming Tweets in the terminal window (see above)
Press /play message or other transport controls to replay data
Replaced [aka.speech] external with Jeremy Bernstein’s [shell] external and the Mac OS command line ‘say’ command.
Reinstalled Java Development Kit for [mxj] object
I revised the php code for the Twitter streaming project, to use the coordinates of a corner of the city polygon bounding box. That seems to be more reliable than the geo coordinates which are absent from most Tweets.
updated 3/26/2014 – fixed runtime error in php server
updated 2/2/2014 – simplified user interface and updated audio engine
updated 9/2/2013 for Twitter v1.1 API with Oauth – note that older versions of this project are broken due to discontinued Twitter v1.0 API as of June 2013
This patch demonstrates the Twitter search API. Its self contained within Max – using the [mxj search tweet] external. This object allows you to input
keyword
maximum number of results
The response is:
username
Tweet text
date/time
This patch is a great way to get Tweets into Max. You can use a [metro] object to poll the API. There are no additional programs running outside of Max.
The limitation is lack of flexibility. You don’t have access to any of the other parameters in the request response. For example, geographic data. Also, it can be difficult to install and maintain java [mxj] programs in Max.
Here’s a screenshot of a patch which takes the output of the above patch and sends it to the aka.speech object – which runs the Mac Os built in text-to-speech program
Happened to look at mashape.com again today. Its grown considerably over the past year and now provides access to over 1300 API’s with open source client libraries and Oauth proxies.
Mashape is an API of API’s – a layer of abstraction that standardizes how you consume API’s.
