Thank you for sharing. And it looks like Nickf is correct.



If that helps, here is a count of files begining with 'FORM' in the original samples. These files are presumably IFF files, and so contain a header of around a hundred or so bytes in the originals.



There are 4662 files with headers in the collection, from 10557 files total.



You can't load these files as raw 8 bit signed PCM, you need at least to skip the header before converting, or better, parse the header and use its info (like sample rate).



The other files should be ok though, they should be raw 8 bit signed PCM data (probably most of them being at 8363 Hz or 16726 Hz sample rates, if they follow the rates of most IFF files).



Here is a count of samples with a header by directory in the Aminet archive:
