Import rejection of some MP3 files

[dannopcs]

Good day.  I am using Audition 3.0 Build 7283 on Windows 10 Pro.  I have been using Audition since it was Cool Edit Pro, but I am no expert.  I have some songs that were converted from WAV to MP3.  All the files were created using the same process.  I am trying to create one file with clips of the four songs.  Audition allows me to enter 2 of the files, but gives me an error message that the other 2 files are not the same format.  I used Audition to open, and save all 4 files individually to the same MP3 format.  No change.  Any suggestions?  Any help will be appreciated.

Thank you, Dan Wilson...

Do you still have the .wav files of the four songs available? It would be much better to compile into one .wav from those rather than having to import the .mp3's back into Audition where they become .wav files again. Then once compiled would still have to be reconverted back to a single .mp3 but with another loss of audio quality.

When you say 'Audition allows me to enter 2 of the files, but gives me an error message that the other 2 files are not the same format' what are you actually doing? Where are you 'entering' the files. Are you loading them into Audition's Waveform view or where?

Good day RYCLARK.  Thank you for responding to my question.  After some frustration, I did most of what you suggested on my own although a bit differently.  The error message provided me with the option to convert the error format to WAV format.  I then merged the four clips into one and saved the result in MP3 format.  I understand your suggestion and that will work also.  What caused the error was trying to import the 4 clips into the Multitask page.  No matter how I did it, 2 of the files imported, the other 2 files gave me the error message.  All of the clips were created using the same process of importing the WAV file, trimming leading and trailing silences, normalizing to 90% and saving in MP3 format.  I couldn’t see any differences in the file formats.

Thank you,
