Okay, so I know [soundfiler] does exactly this: gives the sample size of a file from its left outlet. However, it is also heavy handed, in that it is causing audio dropouts while another file is playing using readsf~
I know that [soundfile_info] from iemlib does this. However, it's not compiled for 64 bit MacOS and I also need it to run on a Raspverry Pi as well.
Are there other solutions?
