In order to support .aif and .mp3 files in Beat Assistant, you need to install the separate tool LAME. Beat Assistant then uses LAME to convert .mp3 and .aif to .wav before running the beat detection.

LAME is available for free under the LGPL license (for details see the website of the LAME Project).

Installing and configuring LAME

  • Mac OSX

    download LAME 3.99 for Mac and save the file lame in the folder /usr/local/bin/. It is just a single, executable file and does not need to be installed. If you don't have access to the folder /usr/local/bin/, you can also store it wherever else you want and in the configuration of Beat Assistant (Step 4 below) click on "Choose File Manually" to tell Beat Assistant where the file lame is located.
  • Windows

    download LAME 3.99.5 for Windows unzip it and copy the content into a folder C:\Program Files\Lame For Audacity. From all the files in the zip, BeatAssistant actually just needs the file lame.exe. If you have this file in the location C:\Program Files\Lame For Audacity, Beat Assistant will find it when you click on "Automatic Detection" (see step 4 below), but you can also copy the file anywhere else and then in the configuration click on "Choose File Manually" instead of "Automatic Detection".
