I have a couple Android recordings that I need to convert to wav, so
I went to use my copy of audacity-freeworld to do the conversion. It
crashed on opening the flie. I have the LAME files and haveworked
with mp3 files fine in the past.
AMR is *not* mp3.
I cannot find anything about problems on this.
I don't think you looked very
hard.
Anyone know anything about it or other methods to convert amr files?
"The amr file extension is for Adaptive Multi-Rate compressed audio.
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized
for speech coding."
Use a tool like sox to convert the files to mp3 or wav directly.
sox /mypath/my_audio.amr /mypath/my_audio.mp3
or
sox /mypath/my_audio.amr /mypath/my_audio.wav
Then work with them in audacity. When you are done, if you want them
back in amr, reverse the process with sox.
