Two of them don't play. ----------- example 1 - NOT playing in audacious ------------------------- General Complete name : example.amr Format : AMR Format/Info : Adaptive Multi-Rate File size : 3.54 KiB Duration : 5s 560ms Overall bit rate mode : Constant Overall bit rate : 5 200 bps Audio Format : AMR Format/Info : Adaptive Multi-Rate Format profile : Narrow band Duration : 5s 560ms Bit rate mode : Constant Bit rate : 5 200 bps Channel(s) : 1 channel Sampling rate : 8 000 Hz Bit depth : 13 bits Stream size : 3.53 KiB (100%) ----------- example 2 - NOT playing in audacious ------------------------- General Complete name : example2.amr Format : AMR Format/Info : Adaptive Multi-Rate File size : 1.83 KiB Duration : 1s 782ms Overall bit rate mode : Constant Overall bit rate : 8 400 bps Audio Format : AMR Format/Info : Adaptive Multi-Rate Format profile : Narrow band Duration : 1s 782ms Bit rate mode : Constant Bit rate : 8 400 bps Channel(s) : 1 channel Sampling rate : 8 000 Hz Bit depth : 13 bits Stream size : 1.83 KiB (100%) ----------- example 3 - playing OK in audacious ------------------------- eneral Complete name : example_works.amr Format : AMR Format/Info : Adaptive Multi-Rate File size : 23.9 KiB Duration : 30s 640ms Overall bit rate mode : Constant Overall bit rate : 6 400 bps Audio Format : AMR Format/Info : Adaptive Multi-Rate Format profile : Narrow band Duration : 30s 640ms Bit rate mode : Constant Bit rate : 6 400 bps Channel(s) : 1 channel Sampling rate : 8 000 Hz Bit depth : 13 bits Stream size : 23.9 KiB (100%) ---------------------------------- I do not see any significant differences between mediainfo output of these 3 samples
