- Apart from the general purpose compression utilities (which will get you
- somewhere), there are two speech specific compressors available by anonymous
- ftp:
-
- Lossy: ftp.cwi.nl:/pub/adpcm.shar
- Lossless: svr-ftp.eng.cam.ac.uk:misc/shorten-0.4.shar
-
- This looks like a good time to say this new release of shorten, version 0.4,
- fixes one bug for compression of sun .au files, and does a bit of tidying
- up. I can mail shorten-0.4.shar (63159 bytes) to anyone who wants it and
- lacks sufficient internet connectivity.
