How To Convert Sample Type (Stereo to Mono)

This tutorial will show you how to use Convert Sample Type in Adobe Audition CC to convert an audio waveform to different channels.

Mono= 1 Channel of Audio (same audio in both ears)
Stereo= 2 Channels of Audio (audio in left can be different than right)

For Podcasters (Mono or Stereo?)

I recommend mono for the majority of podcasters because mono files are smaller in file size, the audio quality is just as good, and one channel is simpler to work with than two.

  1. Mono is recommended for spoken word podcasts (which are the majority of podcasts). Note: Mono is fine even if you have music or sound effects in your intro/outro.
  2. Stereo is recommended when sound effects and music are essential to the show (audio dramas, storytelling, ASMR…)

The all-purpose podcast export setting (Mono):
Mono, 96 kbps, 32-bit float, mp3

The all-purpose podcast export setting (Stereo):
Stereo, 128 kbps, 32-bit float, mp3

How to tell if an audio file is Mono or Stereo?

  1. Look in the bottom right corner of Adobe Audition for Sample Type (44100 Hz, 32-bit float, Stereo or Mono)
  2. Look for ‘Channel’ in Metadata Panel (Window…Metadata)
  3. Look to the right of Waveform (if you see L/R then that is Stereo)
  4. Look at the level meters (1 = Mono…2 = Stereo)
