Advice FFmpeg is not shipped with Audacity but you can download it and then export as WMA (version 2) by following these instructions.

Audio Options


Sets the number of channels for the exported audio file. There are three options

  • Mono: single channel
  • Stereo: stereo pair with left and right channels - this is the default setting even if you only have mono tracks for exporting
  • Custom mapping: use this to export multi-channel (surround sound) files or to make customized assignments between Audacity tracks and the channels in the exported file.

Sample Rate

Sets the sample rate for the exported file. Default setting is 44100 Hz, which is CD quality.

Bit Rate

Choose a bit rate from 24 kbps to 576 kbps. The default is 180 kbps. This produces a larger file of higher quality than default 128 kbps MP3 encoding, the general consensus being that WMA v2 and MP3 produce comparable quality for the same file size. Increasing the WMA bit rate will increase the quality further but produce larger files.

WMA version 2 only supports CBR (constant bit rate) encoding. This means that increasing the sample rate in Audio Settings Preferences will not produce larger files.
