Digital Sound Files and the ContentDepot


2. Encoding Audio Files (Page 1 of 2)



Once you have created your master sound file, you need to encode the file into the proper format for ContentDepot use. For example, you will encode your broadcast audio as MP2, but audition audio as MP3. If you are using a batch encoder, you can make multiple conversions in one session when necessary, but always begin with your master sound file. This way, you get the highest possible audio quality and avoid the degradation associated with multiple conversions from one format to another.

You may use the tools of your choice to encode your files, but you must set the encoding parameters correctly for each PRSS file. The relevant encoding parameters are:

  • Mode
  • Bit rate
  • Sampling rate
  • Word length
