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 Architecture: m68k-amigaos This sample compression package consists of: - a CDRipper for Thoshiba CDRoms (and some IDE/ATAPI drives!) - a RAW PCM and AIFF to ADPCM converter (use e.g. for MPeg Audio) - 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) Release 4: release on Aminet 30-Jul-97 - added the Hifi2ADPCM program. 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. // \X/ Flowerpower
