This is because the newer FFmpegs include a native amr decoder and the default sample format for them is float whereas the default for the opencore amr decoder it 16-bit. When using the "ffmpeg" command to decode a amrnb file, it spits out the following message: Incompatible sample format 'flt' for codec 'pcm_s16le', auto-selecting format 's16' So, the ffmpeg command line tool can detect and handle sample format differences. It seems that Audacity can not. Looking into why.
