an I know from the Internet page of the Bat cording systeme that the RAW files have no header samplerate 500 kHz little endien format PCM 16-bits other WAV files from an other Bat-cording system have Channels : 1 Sample Rate : 312500 Precision : 16-bit Sample Encoding: 16-bit Signed Integer PCM so i tried a batchfile to convert @echo cd C:\temp\sox-14-4-2 for %%i in (C:\temp\*.raw); do (sox.exe -r 500k -b 16 -L -c 1 %%i -r 312500 -b 16 -L -c 1 .\converted\%%i.wav) pause but i get this back: sox.exe FAIL formats: bad input format for file `C:\temp\20230523-N091_B0220-000014.raw': sampling rate was not specified I thought the "-r 500k" is the information for the sampling rate.
I thought so too... I've not used FOR in batch files, but it looks wrong to me. For sox to find the input file it needs the first "%%i" to be the whole path and file name of each of the input files. But if that is so, surely the "%%i" in your ".\converted\%%i.wav" is also a whole path? That can't be right. Surely there you only want a file's basic name, which looks to me as if it should be "%%~ni" - according to what "help for" tells me. If you replace your FOR with for %%i in (C:\temp\*.raw); do (echo sox.exe -r 500k -b 16 -L -c 1 %%i -r 312500 -b 16 -L -c 1 .\converted\%%i.wav) - note the "echo" - you should see what the issued commands look like. If I were you I'd not use FOR until you can make a single command for a single file work properly. If the problem isn't with FOR, another possibility is that you need to tell sox how the input file is encoded. That's the -e ENCODING, --encoding ENCODING parameter. Also, (I don't know), perhaps trying -V3 (to get verbose output) might give a clue. -- Jeremy Nicoll - my opinions are my own _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
