Building the pod – episode 139

This week, a very quick look at the Automatic Click Remover,
followed by a slightly more lengthy look at the Automatic Phase Correction tool,
plus a couple of listener e-mails answered regarding splittting a multi-song multitrack project into individual song projects, and how to capture the sound of scrubbing the CTI across a waveform.

Building The Pod – episode 137

This week, a quick follow up clarification on something I mentioned in ep#136 regarding the ‘order’ of filters. Thanks to Jim Weishorn for pointing out the ambiguity (or error) of my comments.
Then Ron Tostevin asked about purchasing a second-hand Mackie Control Universal off EBay now that the prices of same have come down so much.
Also, the ‘Donate’ button is now back on audio2u.com, so if you feel like making a donation toward paying for the bandwidth, that would be greatly appreciated!
And then, it’s on to the ‘modulation’ sub-menu of the effects menu, which includes Chorus, Flanger and the Sweeping phaser.

Building the pod – episode 135

This week, a couple of listener e-mails answered.
For those wanting to hack into their registry for import/export of keyboard shortcuts, the address you’re looking for is:


For anyone wanting to learn more about Mastering, Brad Blackwood’s forum is here.

Then, a quick look at the Quick Filter.

Building the pod – episode 133

Filed under: !Podcasts,Building the Pod,Notch filter — Bruce Williams @ 12:00

This week, we look at the notch filter.

The waveform view of our sample audio

The spectral view of our sample audio.

Note the pink line running horizontally across the display between 5kHz and 6kHz

The spectral view of our sample audio, zoomed on the vertical scale

Here we can see that the offending tone is actually around 5700Hz

Spectral view after a 25dB cut

Notice how the line of the offending tone is approximately the same colour (and therefore the same amplitude) as the surrounding audio

Spectral view after a 15dB cut

Spectral view after a 45dB cut

Here, we can see that we’ve scooped out too much, which has left a hole in the audio we wanted to keep around the 5700Hz region

Sine Language – episode 111

This week, an apology to Jay for incorrectly identifying him as the author of the e-mail I read out in ep 110,
Jim Weishorn wants to discuss dynamics some more (that’ll have to wait),
a query from Steve Riekeberg at Geek Cred on the voice track processing I use in post-production (see notes at the end of this post),
Mike Wills pointed out the holophone 5.1 microphone,
a couple of people suggested the ‘limited dynamic range’ modes in home AV receivers to combat the wildly varying volume in movies,
Jim Weishorn mentioned this article on using multiple reverbs,
MMIH chimed in with some further input on movie soundtrack mixes, DVD audio, centre speakers etc, including a link to this article from Dolby on setting up home theatre,
Justin confirmed that sound travels FASTER in WARMER air,
plus I discuss the different types of reverbs (plate, spring, digital, convolution).
Oh, and the Speakerphone plugin that MMIH mentioned is made by Audioease.

And finally, those voice settings I supplied to Steve:


Reverb time: 800-1000ms
Initial delay: ~30ms
Diffusion: ~75%
Mix: 95% dry, 5% wet (this is the critical one… most people go overboard on the wet signal!)


Voices: 2
Spread: Wide
Initial delay: 15ms
Pitch: pretty close to neutral (ie don’t shift the voices up or down)

Building the pod – episode 131

Filed under: !Podcasts,Building the Pod,FFT filter — Bruce Williams @ 17:18

In episode 131, we look at the FFT filter.

From the help file:

“(Fast Fourier Transform) An algorithm based on Fourier Theory that Adobe Audition uses for filtering, Spectral View, and Frequency Analysis features. Fourier Theory states that any waveform consists of an infinite sum of sine and cosine functions, allowing frequency and amplitude to be quickly analyzed. Higher FFT sizes create more precise results but take longer to process.”

This week, we move on to the ‘filter and eq’ section of the effects menu.
First cab off the rank… dynamic eq.

Building the pod – episode 129

Finally! BTP is back for 2009.
In this episode, we continue from where we left off with the last 3 entries in the “Delay and echo” sub-menu of the effects menu.
Also, Michael Rooney has been slaving away over a hot text editor, cranking out utilities for use with Audition.
Check out the Audition FX Management utility, and the SES Backup utility.
And if you find them useful, please make a donation (even if it’s only a couple of  bucks)!

Filed under: !Podcasts,Analog delay,Building the Pod,Delay,Dynamic delay,Effects rack — Bruce Williams @ 13:52

In episode 128, we explore the first half of the “Delay and echo” submenu items in the effects menu.
Also, my plans to move my home studio in the new year, and this week saw the release of the Audition 3.0.1 patch. See the previous post for details.

Building the pod – episode 127

In ep 127, we start (one more time!) working our way through the effects menus of Audition 3, starting with the ‘Amplitude and Compression’ submenu items.

Sine Language – episode 100

Yes folks.
Believe it or not, we’re finally here!
The building of this video has been an absolute labour of love…. I’d estimate that it’s taken me about 20 hours of work to complete!
Maybe, that’s partly my inexperience at producing video podcasts, but hopefully, when you watch it, you’ll see where those hours went.
In an effort to ease the load on my hosting company’s servers, I will be setting up a torrent feed later tonight.
Check back here later for a link to the torrent file.
There’s also a copy of the file at YouSendIt, plus the copy here at audio2u.com.

To download manually from audio2u:
sl100.mp4 280MB

From YouSendIt here:
sl100.mp4 280MB

If you want to download a copy of the final mix of the song (featuring a couple of extra tweaks I did later), grab that here:
Fear of Holding On – 320 kbit joint stereo (13MB)

Towards the end of the podcast (or is that vidcast?), I mentioned that I would make the individual instrument tracks available to anyone who wanted to have a crack at mixing the song for themselves.
Drop me an e-mail and I’ll send you the link to download the files.
Just be warned… that’s an even bigger download than the mp4!!
The tracks are 32bit mono and total about 1.1GB!
The download will be in .rar format, so you’ll need an archive utility like WinRAR (or similar) which is capable of unzipping a .rar file.

This week, a discussion on handling noise within your home, prompted by a discussion I had with Luke Stapely on Facebook.

Filed under: !Podcasts,Building the Pod,Effects,Facebook,NAB,Plugins,Sidekick,trade show,VST — Bruce Williams @ 10:02

This week,
Jim Perry asked about monitor resolution,
and Valente Espinosa asked about sidechain compression (even if he didn’t realise that that was what he was asking about!).
And it just so happens that there’s a free VST plugin which does sidechain compression!
It’s called Sidekick.
Also, Bruce is heading back to the States to visit NAB (can’t wait for that!),
he’s finally succumbed to Facebook,
and he needs your help with some “stuff”.

Audition v3 Graphic Phase Shifter

Filed under: Building the Pod,Effects — Bruce Williams @ 23:09

Hi all,
Just noticed this on the beta tester’s forum and felt I ought to mention it straight away.
It seems that Audition v3 shipped without the Graphic Phase Shifter tool.
This was apparently quite unintentional on Adobe’s part.
So, they’ve posted the dll (in a zip file) on the Adobe servers for you to download and install.
Installation is quite simple.
Just extract the zip file, and move (or copy) the dll to the C:\Program Files\Adobe\Adobe Audition 3.0\Plug-ins\ folder.
Then, next time you run Audition v3, refresh your effects list and you’ll be good to go.
