Changing SMPTE Timecode start on a Broadcast Wave file

There is a great reference available in Broadcast WAV files that allows many audio editing programs to display an embedded timecode stamp that was given to it from the audio program that created the file. I have found that when these files come from the audio team, they don’t necessarily have the correct start time entered (since no-one really needs to use it). However, it becomes very handy when you are programming offline and need to get markers in, in a program like Twisted Wave for example.

Go here and download Wave Agent (

Once installed, open Wave Agent. Drag the WAV file that you wish to alter into the large area at the top, or from the File menu, click on Import.

At the Recording Info area in the center bottom of the display, click on Frame Rate and select the rate that your timecode audio file is running at.

Make sure that Preserve Start TC is checked and then click on Edit. Change this time to match the time of where the timecode stripe on your audio file is starting at (if you’re not sure, ask the person who generated the audio file or run it through an actual SMPTE clock to find out – reference my earlier post on reading SMPTE on a mac to be able to do this).Screen Shot 2014-09-15 at 5.17.12 PM

My SMPTE stripe is actually starting at 08:00:00.00 however there is something weird in Twisted Wave that it displays the WAV file early by one frame, so I correct it here to make up for it.
Update: Twisted Wave version or later has fixed this math error, so enter the actual start time; In this example it would be 08:00:00:00.

Click OK and then the SAVE button at the far left bottom most corner. Click OK to confirm and then after it’s done, you can close Wave Agent.

Open up Twisted Wave and then its Preferences. Under Time Display check Use time origin from audio file and then select the same frame rate that you encoded the file at in Wave Agent.

Accept those settings and you should now see the start time you put into Wave Agent (minus one frame) in the cursor position readout at the top right of Twisted Wave

What is nice about this setup, is that when you use Markers, the marker time will accurately reflect where that is in your timecode stripe. Very useful for cueing very tight segments for consoles without a learn function.

Philips Hue Control From AppleScript (For Use in iCal and Calendar)

UPDATE:I created this entry before an API came along that made all this easier. Some great documentation on how to do all of the below is listed here

The Hue Series LED bulbs from Philips are very hackable and can be controlled via simple HTML Put commands. I have assembled a few things to get you started in some simple preset control via AppleScripts. I’m using this method to create an appointment in Calendar to automatically turn on and off these lights.

Before you start with all this, you should know/set the IP address of your base station. You can set the IP address of your bridge using the Hue app on iOS.  Go to the settings in the Hue app and then click on My Bridge/Network Settings. Turn off the DHCP switch and then set your IP below.  Click Save.

So now that you know your IP address, you’ll need to configure your bridge to accept commands. Go to this site ( and follow the first page of steps up past where you create the user “newdeveloper”.

You’ll need to know which Hue Lamp you wish to control. The order that the lamps appear in the myhue website or the iphone app, is the same order that they are numbered. I’ve put markers into the scripts where you’ll paste and enter this info.

The first script you can use to see what your lamp is doing. This is useful to get the values of the color you have selected through the app that you can then paste those values into the other scripts to recreate the values that you set.  So first, using the app, set your lamp to the desired color and intensity.  After editing the script to include your IP address, API Key, and correct lamp; Run this first script to see the lamp values:

Get Bulb Status

set pollBulb to do shell script "curl"

The important bits you’ll need from this are the Brightness (bri), Hue (hue), and Saturation (sat). Here are some sample values

{\"on\": true,\"bri\": 254,\"hue\": 12813,\"sat\": 219,\"xy\":[0.5196,0.4141],\"ct\":484}

To turn the lamp on at the value you found, you’ll change this next script to reflect what you found:

Lamp On

set turnOn to the quoted form of "{\"on\": true,\"bri\": 254,\"hue\": 15331,\"sat\": 121}"
do shell script "curl --request PUT --data " & turnOn & ""

Finally, here is a script to turn the lamp off:

Lamp Off

set turnOn to the quoted form of "{\"on\": false,\"bri\": 254,\"hue\":15331,\"sat\":121}"
do shell script "curl --request PUT --data " & turnOn & ""

So there ya go. Applescript yourself away.

Mountain Lion Archive Bug

There is a bug in Mountain Lion (10.8.2) where you go to click on a compressed file to unzip it and your system just hangs and wont unzip it, forcing you to force quit the unarchiver.  Until they fix the bug, you can run this workflow to quickly kill the correct service. It will restart when you try to unarchive something again.  Drop this into your ~/Library/Services folder and then you should see it in the Services Menu under every application drop down on the menu bar. If you don’t see the service appear, open Services Preferences and scroll down to make sure there is a check mark next to the same of this workflow.

Compressor Fix Workflow

Q: But wait, how do I unzip this if the reason I came here was to get my unarchiver working again?
A: You can either reboot or type the following into Terminal:

sudo killall -KILL appleeventsd

The actual workflow is an applescript that does the following:

do shell script "sudo killall -KILL appleeventsd" with administrator privileges

Here’s the source:


Setting up your Mac as a SysLog Server (for Pharos and Mosaic)

The past few years I have been using Pharos and Mosaic for all of my attraction programming (and some other random stuff too) and amidst debugging I heavily rely on the logs to see what triggers it’s getting and how things are playing in real time; Which is something the Web Interface in Pharos/Mosaic doesn’t show well in its update every 4 seconds or so.  There are quite a few good SysLog Servers you can install for Windows but for Mac you don’t need to because you have one built in, in the form of the Console application. It just requires a few settings to ‘unlock’ that functionality. Before you get started on all the below, I recommend you go install XCode (in the Mac App Store) right now. Later you’re going to need to edit a bunch of preference and conf files – XCode will ensure that things stay in check easily when you save them after editing.

I pulled this information from the following websites:

Setup (using XCode)

Apple provides the Property List Editor utility as part of its developer tools (XCode).  The developer tools are usually a separate install from the operating system and is frequently not installed on systems.  If it is present, then using the Property List Editor may be the most convenient means of modifying the file.

  •     Login as administrator to the logging host
  •     Open the /System/Library/LaunchDaemons/ file using XCode.
  •     Select the “Sockets” dictionary entry and “Add Item” to create a new key in the “Sockets” dictionary
  •     Change the name of the item to “NetworkListener” and set its type to “Dictionary”
  •     Select the “NetworkListener” dictionary entry and “Add Item” to create a new key in the “NetworkListener” dictionary
  •     Change the name of the item to “SockServiceName”, its type to “String” and its value to “syslog”
  •     Select the “NetworkListener” dictionary entry and “Add Item” to create another new key in the “NetworkListener” dictionary
  •     Change the name of the item to “SockType”, its type to “String”, and its value to “dgram”
  •     Save the file and quit XCode.  The property list should resemble the following example

  • Open a terminal session using the Terminal utility
  • Navigate to the LaunchDaemons directory
    cd /System/Library/LaunchDaemons
  • Stop the currently running instance of the syslog daemon
    sudo launchctl unload /System/Library/LaunchDaemons/
  • Restart the syslog daemon to pick up the changes in the LaunchDaemon configuration
    sudo launchctl load /System/Library/LaunchDaemons/

OS X can use normal log files like any BSD, but it also comes with a built in data store for log messages. Data stores are fast, log rotation comes built in, and they are indexed and quickly searchable. I like my network syslog files routed to a different data store. Data store routing is configured in /etc/asl.log. Filtering can be done on a number of fields, the simplest one is “Host”, which will be the router name taken from “/system identity”. The “Sender” field is taken from the prefix configured under “/system logging” for the topic. I store my Pharos syslog messages in /var/log/pharos in data stores named by date in /var/log/pharos. The directory has to exist, the below creates it with read access for everyone on a directory level (everyone can list files):

sudo mkdir /var/log/pharos
sudo chown root:staff /var/log/pharos
sudo chmod 0755 /var/log/pharos
  • Find the file /etc/asl.conf and copy it to the desktop (maybe make two copies of it for when you mess up!). Open asl.conf in XCode and add the lines below to the end of the file to make the Pharos/Mosaic point its data to the above directory (lpc entries are relevant to Pharos, msc to Mosaic. You may omit the ones you don’t need):
    # dont post messages to all messages
    ? [= Sender lpc] ignore
    ? [= Message lpc] ignore
    ? [= Sender msc] ignore
    ? [= Message msc] ignore
    # save pharos log files
    ? [A= Message lpc] store_directory /var/log/pharos uid=0 gid=20 mode=0644
    ? [A= Sender lpc] store_directory /var/log/pharos uid=0 gid=20 mode=0644
    ? [A= Message msc] store_directory /var/log/pharos uid=0 gid=20 mode=0644
    ? [A= Sender msc] store_directory /var/log/pharos uid=0 gid=20 mode=0644
  • Using Terminal, move (sudo mv in unix speak) your new edited asl.conf file from the desktop to /etc/ and overwrite the file there. This process seems to screw up the permissions on the file so run ‘Repair Disk Permissions’ in the Disk Utility app to fix it.
  • Finally, restart the syslog daemon to have all the changes take effect:
    sudo launchctl unload /System/Library/LaunchDaemons/
    sudo launchctl load /System/Library/LaunchDaemons/
  • On the Pharos/Mosaic Network Tab, configure the syslog entry to point to the IP address of your mac and I also recommend changing the level to ‘Verbose’ (you can also change this in the Web Interface under the Configuration tab).

That should be it! Hopefully when you open the Console app and scroll down you should see your Pharos entry (obviously if you’re using Mosaic, just replace all references to that name in the above instructions). Here’s what mine looks like – I’ve blocked out the IP address next to the date (it’ll display the IP address of the controller sending you the info) but you get the idea.

Outlook for Mac Notification Center New Message Alert

Using MacPorts, there is a program called “Terminal Notifier” that can send alerts to Notification Center in Mountain Lion based off of a command line entry and thus an Applescript. Obviously, you can have a lot of fun with that – but I specifically found it so that I could send a new message alert from Outlook because Microsoft only has such a notification appear on the active desktop and I use several of them in Mission Control. I compiled this information from these sites:

To get this to work isn’t so bad once you have MacPorts installed, which I’ve referenced earlier.

  • Assuming MacPorts is already installed, run the selfupdate command (also listed in that earlier post).
  • Install Terminal Notifier:
    sudo port install terminal-notifier
  • Download and put this AppleScript into your Documents/Microsoft User Data/Outlook Script Menu Items (you don’t have to put it there, but just for organizational sake, might as well). Sure it says Growl in everything below as that is what I originally used it for but then changed it to accommodate Notification Center instead:Improved Growl New Mail.scpt
  • In Outlook, create a new rule that will run the script based on your criteria. Here’s mine:

That’s all there is to it.


MacPorts Installation and Sending UDP Messages from the Command Line and Applescript

UPDATE: A very easy tool to send UDP commands can be found here

Spurred on by one of my colleagues, I found a way to be able to send UDP messages from the command line without a lot of fuss. Granted, you do have to install some things on the backend, and any applescript you make wont be able to run on any computer unless this same process has been completed, but it’s still useful if you need to send UDP messages (say to a Pharos/Mosaic/Eos). This was all done in Mountain Lion 10.8.2:

  • Follow the instructions here up to the point where it gets you to install the game – don’t do that. They refer to Darwin Ports everywhere – it’s actually called MacPorts now.
  • You can find the install for MacPorts here:
  • When in the instructions on the site, it tells you to change to the darwin ports directory, this is the command instead:
    cd /opt/local/var/macports
  • Anytime you see “dports” substitute “macports”.
  • After you’ve gotten through all the above, you’ll want to install the program “socat” which will allow you to send the UDP messages:
    sudo port install socat
  • Once that has installed sucessfully, you should now be able to send UDP messages now like the following. You would replace “HELLO” with the text you wish to send and then change the IP and port number to the device you’re sending to:
    echo "HELLO" | socat – UDP-DATAGRAM:,broadcast

Now for the actual Applescript, that part is easy, you just have to insert a “do shell script” command into an applescript where you can ask for variables, etc.  Here’s an example:

set UDPstring to the quoted form of "Hello_Does_This_Work"

do shell script "echo " & UDPstring & " | opt/local/bin/socat - UDP-DATAGRAM:,broadcast"

MacPorts has some other fun things you can install, like Terminal Notifier for instance. Here are some commands to remember:

  • To make sure that your installation is up to date and to upgrade anything you may have installed through MacPorts, run these two commands:
    sudo port -v selfupdate
    port upgrade outdated
  • To search for a particular program or to list all the programs (replace {name} with your search criteria:
    port search {name}
    port list
  • Finally again, to install a new port, the command is:
    sudo port install {portname}

As usual, YMMV and always backup your computer before you do something you’re unsure of.  Good Luck!
