There is a number of _ancient_ formats supported by SoX. If you are using the Ensoniq Paris II, like people did in 1998, SoX will play the *.paf files for you? What use is it now? > Stamping out speex format won't stamp out > people who happen to have or receive files in speex format. When is the last time you needed to read or write a *.spx file?

FLAC files can include a jpeg of the album cover? Does SoX extarct it for you?

No. As a side note, this was a thread about speexdsp header files. Now we're at this again.

Sox disapponted me here. You should probably turn to something else then. _______________________________________________ SoX-devel mailing list SoX-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sox-devel
