Short: Highly effective sample compression utils
Author: flowerp@eikon.e-technik.tu-muenchen.de (Christian Buchner)
Uploader: flowerp@eikon.e-technik.tu-muenchen.de
Type: util/pack
This sample compression package consists of:
- a CDRipper for Thoshiba CDRoms (and some IDE/ATAPI drives!)
- a converter for any sound format to ADPCM using datatypes
- a stand alone ADPCM replayer with wildcard support
- an ADPCM DeliPlayer for use with DeliTracker
- an ADPCM datatype for use with e.g. MultiView
Even better: ALL THIS IS PUBLIC DOMAIN, FULL SOURCE CODE INCLUDED!
What has changed since the first release?
-----------------------------------------
Release 2: release on Aminet 5-Oct-95
- all programs got a version string
- fixed makefile of ADPCM datatype
- PlayADPCM slightly updated (->V1.1)
- reduced chip buffer size for the DeliPlayer to 1K (->V1.1)
- The DeliPlayer got a realtime loader and a NotePlayer interface (->V1.2)
- the ADPCM datatype descriptor was buggy (marked as picture!)
- improved X2ADPCM's datatypes error output (->V1.1)
- I got a new address and phone number!
Release 3: release on Aminet 22-Oct-95
- small fixes to the DeliPlayer's Noteplayer interface
- CDripper got NumTracks option, Maximize and Boost abilities (->V1.1)
What is ADPCM?
--------------
ADPCM is a lossy sample compression method allowing a very high compression
ratio. The drawback of this compression technique is an audible noise
level, but this is still acceptable.
Example
-------
You can rip off a 3 minute music track from CD ("Cotton Eye Joe", 22050Hz,
Mono) and store it in 982999 bytes. This can be further reduced by about
10% using an ordinary packer. You can listen to this audio track with
DeliTracker just like an ordinary sound module.
