Opening .AMR files with Adobe Audition
I recently had to conduct an interview for a Public Speaking class I am taking. I didn’t have any suitable equipment to record the interview so I had to use my cell phone. After the interview I downloaded the recording to my computer and saw that the file’s name ended with “.amr”. I had never encountered such files before, so I did some research and it turned out that “amr” stands for “Adaptive Multi-Rate” codec. This is a compressed audio format that was originally developed by Ericsson and is used by many 3G cell phones for voice recordings since the algorithm that is used for the encoding was designed to efficiently compress human speech audio.
I have some previous experience with digital audio editing and have Adobe’s excellent Audition software installed on my computer. However, the latest version (3.0) does not have built-in support for .amr files. Luckily, I found a free plugin that could help me - a big THANK YOU to the guy that developed the plugin and generously shared it with the community. To download the plugin, click here.
