Capturing Audio with Winamp

IMHO, Winamp's greatest feature is its versatility via plugins, and of course a huge community of users who write plugins for it. I had been looking for a simple way to capture audio from my mic to my HD, but most tools out there were shareware with trial periods etc. and the only tool I found, Absolute MP3 Recorder, refused to work on my system. I finally turned to trusly ol' Winamp, and found a wonderful plugin called Line-In Plugin (Winamp download) by Jasper van de Gronde (email, homepage) that allows, well, audio from in line and mic to be played in Winamp. Then it was a simple matter of using the Nullsoft Disk Writer Plugin (comes with Winamp) and choosing the appropriate audio capture settings on the input plugin. If you have problems with this, I have step by step instructions below.

  1. Download and install Winamp Line-In plugin using the links above.
  2. Open the Preferences window by pressing Ctrl+P and choose Input under Plugin from the left column. Choose the Line-In Plugin.
  3. Configure the Line-In plugin. A readme file comes with the plugin and is stored in the plugins directory, usually C:\Program Files\Winamp\Plugins\. Use Ctrl+L to open the location window and type in the settings of your choice. I used these settings:
    line://srate=22,bps=8,nch=1,time=1200
    These give me fairly decent voice recording for 20 mins, @ 1.26MB/min which doesn't kill my HD.
  4. Choose Output from Plug-ins and choose the Disk Writer plug-in. Use the Configure button to decide where to store the audio. I would recommend making sure that the max. recording time does not fill up your hard drive. Bad things can happen if your system drive is full.
  5. Now you should see a "song" in your playlist. Playing it will start the recording, pausing will hold, and stopping will write it to disk.
  6. Switch your Output back to whatever it was before (DirectSound or waveOut are common). You are done :-) Encode the wave file into the format of your choice, like Ogg Vorbis or MP3 for reduced space requirement.

Special thanks to the Winamp team and Jasper van de Gronde.
