Please give me a hand finding the format differences between the two attached files.
The file name FILEWRONG.wav does not play in a particular system, but the file named FILEOK.wav plays OK.
On Audacity 2.3.1 I see both the same: Mono, 32 bit, 8000 Hz … I can not find any property different between both files
Thanks and best regards
We don’t make “Audacity 2.3.1” so we don’t support it. Please see the pink panel at the top of the page for how to check the Audacity version number and how to download the current Audacity 2.1.3 from us at: https://www.audacityteam.org/download/.
You did not attach any files. See How to attach files to forum posts. Are these telephone call systems you are using? You should try to find out from the call system manufacturer that does not play all your files exactly what types of file it wants.
Audacity will expand files by default to 32-bit float when you import them. It thus does not mean the files have 32-bit depth. To examine the files you can download “MediaInfo” from http://mediainfo.sourceforge.net/en/Download/Windows. Get the version without installer, because the installer may have malware or adware. Show us the MediaInfo text output for the file that has a problem on the one system and the text output for a file that plays on that system.
