Made a visit to one of our Projects underway in Oakville this week

to take site photos of

the progress of the Work

“Skyventure” iFly Toronto indoor Sky-Diving facility

It is an interesting building with
 unique structural & architectural features
 and i thought it would be cool to record sound
 in the basement plenum space
The foundation is constructed of 14" concrete walls
 reinforced with 1" re-bar in a 12" grid pattern
and the building footprint is 100ft long by 50ft wide with a basement depth of 25 ft

  Standing in the centre of the basement looking up you see an opening
 in the base of a 14ft diameter, 45ft long cylindrical tube
The opening appears to be roughly 1/10th of the diameter of the floating chamber where you chill
until the plenum is fully pressurized using four massive motorized louvers & propellers
generating an airstream capable of reaching wind speeds
of up to 300 kph to simulate the
free fall experience

The distance from the basement floor to the service deck is 80ft (8 stories high)

i used the Voice Note Recording feature on a BlackBerry (Torch), emailed the file to myself and imported it into Audacity

discovered that the file format was not recognized and was prompted  to download  the FFmpeg library

exported it as a WAV file


So how does one download & install the FFmpeg Import/Export Library?

The optional FFmpeg library allows Audacity to import and export a much larger range of audio formats including AC3, AMR(NB), M4A, MP4 and WMA and also audio from most video files.

  • Because of software patents, Audacity cannot include the FFmpeg software or distribute it from its own web sites. Instead, use the following instructions to download and install the free and recommended FFmpeg third-party library.
Warning icon FFmpeg 0.6.2 for Windows and Mac listed below should be used with the latest version of Audacity from


  1. Go to the external download page
    Left-click this link, do not right-click.
  2. Look for “For FFmpeg/LAME on Windows”, then a few lines under that, left-click the link FFmpeg_v0.6.2_for_Audacity_on_Windows.exe and save the file anywhere on your computer.
  3. Double-click “FFmpeg_v0.6.2_for_Audacity_on_Windows.exe” to launch the installer (you can safely ignore any warnings that the “publisher could not be verified”).
  4. Read the License and click Next, Next and Install to install the required files to “C:\Program Files\FFmpeg for Audacity” (or “C:\Program Files (x86)\FFmpeg for Audacity” on a 64-bit version of Windows).
  5. Restart Audacity if it was running when you installed FFmpeg.
  6. If you have problems with Audacity detecting FFmpeg, follow the steps to manually locate FFmpeg.
  • Alternative zip download for FFmpeg 0.6.2
  1. Download from the external download site.
  2. Extract the contents to a folder called “FFmpeg_v0.6.2_for_Audacity_on_Windows” anywhere on your computer, then follow the instructions below to locate avformat-52.dll using the Libraries Preferences.
