updates to audioGraph for iOS 7

Submitted an update (1.2) to Apple for audioGraph today.

Mostly bug fixes:

  • screen size issues in iPod touch 5g
  • missing icon files for retina
  • fixed crash on load
  • made play buttons more visible for triggering samples
  • solved no root view controller error
  • new splash screen for iPod touch 5g
  • etc.,
  • fixed sync issues with github and Xcode

The upgrade to App store is 1.2 but the github version is at 1.3 – as there were a few incidental issues that didn’t get in the submission.

Next release should deal with these issues:

Version 2 should have automatic reference counting and make use of new NSNotification method of handing delegates.

I would like to leave the current version alone and start a new project from scratch – because the iOS dev process has changed greatly in 3 years.

Note: current local source code is in tkzic/coreaudio/audioGraph1.3

github is: https://github.com/tkzic/audiograph

iOS distribution provisioning

notes

While preparing an upgrade for audioGraph today – ran into problems trying to upload and validate the binary (via archive in xcode 5)

The answer:

  • create a new distribution provisioning profile, after registering the upgrade in itunes connect.
  • download the profile and drag into xcode.
  • follow the instructions on this stack overflow post

http://stackoverflow.com/questions/18818381/xcode-5-code-signing-entitlement-errors

Also – there were issues with icons. You need to assign the filenames in the .plist file

developing iOS apps with javascript and phonegap

Just worked through the first example in a tutorial: http://coenraets.org/blog/phonegap-tutorial/

by Christopher Coenraets.

How to develop using phonegap.build https://build.phonegap.com/

  • Write a javascript web app.
  • Submit to github or zip the folder
  • Upload to phonegap.build
  • Compile (for iOS you need to have previously submitted developer certificates)
  • After compiling, scan a QR code (in the browser) using your mobile device. This installs the app

Don’t yet know the steps to getting it in the app store, but this is amazing.

Google speech API v2

notes

update 5/17/2014: The key in the post below is now disabled. Trying this one: AIzaSyBOti4mM-6x9WDnZIjIeyEU21OpBXqWBgw 

It worked for now – but I will probably need to get a real key… and add instructions for inserting the key into the patches: robot_conversation5.maxpat and speech-to-google-text-api5.maxpat

Basic instructions are

  • edit Max patch
  • go into the sub patch: call-google-speech and replace the key string inside the curl command with the correct key.
earlier post

v1 API of Google Speech broke a few days ago.

Here is an example of how to run v2. https://github.com/gillesdemey/google-speech-v2

I have updated the Max patches in the Internet Sensors project. https://github.com/tkzic/internet-sensors

This version of the API produces malformed JSON responses.

Here’s an example using curl:

curl -v -i -X POST -H “Content-Type:audio/x-flac; rate=16000” -T /tmp/tweet.flac “https://www.google.com/speech-api/v2/recognize?xjerr=1&client=chromium&lang=en-US&maxresults=10&pfilter=0&xjerr=1&key=AIzaSyCnl6MRydhw_5fLXIdASxkLJzcJh5iX0M4”

Instructions for getting a real key…  http://www.chromium.org/developers/how-tos/api-keys

Note: Need to look at the double buffering methods in the Max patches to make sure they are handling various sample rates properly. I think they may be optimized for 44.1 KHz
