App of the Day: Audacity

Audacity Logo

As a follow-up to my post on Soundflower, I thought it would be appropriate to make a post about Audacity. To quote directly from the Audacity website:

Audacity is a free, easy-to-use and multilingual audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. You can use Audacity to:

  • Record live audio.
  • Convert tapes and records into digital recordings or CDs.
  • Edit Ogg Vorbis, MP3, WAV or AIFF sound files.
  • Cut, copy, splice or mix sounds together.
  • Change the speed or pitch of a recording.
  • And more! See the complete list of features.

In the past I’ve used Audacity to edit music for content and quality, convert audio files to different formats, record music and record lectures. I highly recommend it to anyone who loves working with audio for fun. There are a variety of plugins available on the web too.

Mini-App of the Day: Soundflower

Soundflower (also available from code.google.com) is a simple, free app that allows you to pass audio from one program to another. It basically masks as a virtual audio device. For example, if you want to record the audio from a certain video, you can play the video in VLC, iTunes or another player of your choice and send it to an input device or software such as Audacity or Max via Soundflower. Once installed, the Soundflower options are easily accessed by pressing alt/option and clicking the speaker volume button in the menubar. From there you have the option of changing the output and input devices. Another alternative is to run Soundflower Bed, which is just a menu app that gives access to more of the functionality. By making Soundflower both the input and output device it becomes your virtual microphone and speakers, effectively recording any audio output to the input device/software of your choice. Unfortunately, it is only available for Mac OS X.

An alternative to Soundflower that has received high ratings is JackOSX.
