How to EQ vocals

Of course there is no exhaustive and conclusive answer to “how to EQ vocals“, but there are some guidelines you can follow and that offer you reasonable results even if you’re not into audio.

You can use the following 4 steps within your audio package of choice.

Step 1 – Remove low frequency rumble
Set your “High Pass Filter” somewhere between 80 and 120 Hz

Step 2 – Add more freshness to audio track
Top shelf, boosting high from 8 kHz with 1 to 6 db (if you want to do it subtle: 12 – 16 kHz)

Step 3 – Reduce offending frequencies
Sweep your vocal track by using a small bell curve, to find offending frequencies round 800 – 1 kHz and reduce them by -3 db

Step 4 – Make vocals more outstanding
Boost the vocal presence in your mix, by boosting the range between 2 – 5 kHz with 1 to 4 db



  • With everything you do while EQ ing your audio, listen carefully to the results!
  • Never work on your original files, always use a copy!

Backing up and restoring software installations in Ubuntu

Sometimes you just want to restore (or clone) your favorite (studio ;-)) installation, to a clean installed, freshly formatted machine, without having to  install manually all your favorite applications again.

This can be done, by exporting the list of all your installed applications to a text file and reinstall all your applications listed in the text file to your freshly formatted machine (as Hannibal would have said “I love it when a plan comes together“).

First create a text file in your ‘Home’ folder containing a list of all your applications of your favorite (studio ;-)) installation. Open a terminal window:

sudo dpkg –get-selections > app-backup-list.txt


Next copy the file “app-backup-list.txt” from your ‘Home’ folder to your freshly formatted machine (your ‘Home’ folder will do ;-). Now to restore your applications, open a terminal window:

sudo dpkg –get-selections < app-backup-list.txt
sudo apt-get -y update
sudo apt-get dselect-upgrade

Firefox zoom not working on Mac OSX

By default the “pinch open” and “close zoom” options are not working in Firefox on OSX. But it’s not that hard to enable the Firefox zoom settings, if you know how to do it…

Open Firefox
Go to a new tab, type in “about:config” and hit <Enter>.
Click the “I’ll be careful, I promise!” button.

You can now modify the related browser.gesture preferences by changing the values as stated below:

  • -> cmd_fullZoomReduce
  • -> cmd_fullZoomReset
  • browser.gesture.pinch.out -> cmd_fullZoomEnlarge
  • browser.gesture.pinch.out.shift -> cmd_fullZoomReset
  • browser.gesture.pinch.latched -> false

Once you have changed the preferences, close the tab and the new settings should work. You might want to restart Firefox!?

Updating Squeezelite on your Raspberry Pi

After running Squeezelite on my Raspberry Pi for a while, I thought it would be time to update Squeezelite to it’s latest version. And this is how I did it…

First you’ll have to login to your Raspberry Pi, you might want to open a terminal and use SSH…

If you don’t have a squeezelite folder, then create one! You can do this by using mkdir in your terminal:

mkdir squeezelite


Now go to your squeezelite folder:

cd squeezelite


Remove an older version, if it’s there:

rm ./squeezelite-armv6hf


Next download the latest version:



Remove the old version:

sudo rm /usr/bin/squeezelite-armv6hf


Copy the latest version to the folder /usr/bin:

sudo cp squeezelite-armv6hf /usr/bin


Setting the permissions right:

sudo chmod a+x /usr/bin/squeezelite-armv6hf


Reboot If you want, else stop start the service:

sudo shutdown -r now


Now you are ready to rock and roll (again) !!!
