I can try uploading them on mega 08:48:53 i think this qualifies as on topic, so consider putting one (preferably form the middle of the list) on transfer.archivete.am instead 08:48:59 *from 08:50:13 do your audio player/ffprobe show errors when run on the wav output, or is there just no sound? 08:59:45 I ffprobed the wav and along with for some reason its entire compilation-time options it gives me this:[wav @ 062c3900] Cannot check for SPDIF 08:59:46 pcm_s16le ([1][0][0][0] / 0x0001), 48000 Hz, 2 channels, s16, 1536 kb/s 09:00:11 Also here are all the files on mega: https://mega.nz/folder/OlwjgaSb#Zvo9q0SluuOUSC6M6UHvAg 09:01:32 I should probably go to sleep now. I have to work later. 09:09:23 also should probably note that my player had a different SoC than the one that article mentions. Mine has a STMP3501 which says it can do WMA and mp3 but is 'upgradeable to other digital music formats.' Datasheet here: https://datasheetspdf.com/pdf-file/542203/SigmaTel/STMP3501/1 10:12:20 i don't even get that far, either because i'm using the latest release ('h00') or because i'm running it through wine--with `-ff raw` i get "Internal Sampling Frequency not supported with AMW WB and caracterized WB+ modes" if i try the first file (or all the files catted together), or "Sampling rate not supported" if i try one of the other files. 10:13:33 (`-ff 3gp` eliminates the error, but exits immediately after printing 'Running' and produces unplayable output.) 10:16:35 building the decoder locally to debug would be non-trivial for me, but maybe someone who knows more about windows could elucidate the visual studio project structure enough to put together some makefiles? 10:26:48 perhaps https://sourceforge.net/projects/vcproj2cmake/ along with 26304_ANSI-C_source_code_v6_6_0\MSVC\decoder\decoder.vcproj 10:28:46 this is all also assuming that the AMR-WB+ format is indeed the format these files are in. 16:36:36 https://mega.nz/folder/OlwjgaSb#Zvo9q0SluuOUSC6M6UHvAg rehosted because MEGA stinks: https://transfer.archivete.am/sJVIL/H..zip 16:42:59 Assuming it is AMR-WB+: ffmpeg doesn't support that: https://trac.ffmpeg.org/ticket/6140 3GP would be a container format (like MKV or MP4) and can *contain* AMR-WB+ data, but raw AMR-WB+ wouldn't be wrapped in 3GP.
