Hi ,

Question as the title says.

I run mp3cat on my MacBook. I will email my source and script files to you later.

Hope you can help me!

Hi Rao. Some of your files are single-channel with a sampling rate of 44.1kHz while others are dual-channel with a sampling rate of 24kHz. I think most MP3 players will choke if you mix such different formats up in a single file. You could try converting them all to a single format before merging them.
