- FIVE TO FIVE V0.9
-
- by Harald Schönfeld and Bernd Spellenberg
-
- 4/12/93
-
-
- 525 coverts sound samples from/into different formats:
-
- - DVSM (Falcon)
- - AVR (ATARI)
- - SND, AU (Sun, Mac, NeXT)
- - WAV (PC)
- - raw data
-
- This program uses the conversion routines of FORTUNE V1.0 that works only on
- computers of the FALCON series and is even able to play these sounds in
- real time from hard disk.
-
- This program is Public Domain in this version. It may and shall be copied
- and spread under the condition that all program- and text- files of this
- archive are included.
-
-
-
- 1. System requirements
-
- 525 runs on all computers of the 680x0 series, no matter if MultiTOS is
- installed or not. 525 needs about 160 KB free RAM.
-
-
-
- 2. Installation
-
- Copy the program (525G.PRG=german, 525E.PRG=english) onto your
- harddisk.
-
-
-
- 3. Usage
-
- After the program starts the 525 menu appears. There are the following
- menu items:
-
-
- Desk/about Five to Five...
-
- Informs about the current version number.
-
-
-
- File/Convert...
-
- Here you can select samples for conversion and choose a new file format.
-
- To select an import file click on the PopUp "Import Sample".
-
- If 525 is unable to recognize any header, a dialog appears, where you can
- select the format of the sample to load:
- - The frequency
- - The pack/data format
- - The number format: Signed or unsigned
- many old ST samples are 8 Bit Mono unsigned.
-
- "Info" shows informations about the current input file. Please pay attention
- to the fact that length is the length of the raw sound data without any
- headers.
-
- "Select sample format"
-
- 525 can read and write samples in 5 different formats:
- - DVSM: For Fortune and WinRec
- - AVR: Many ATARI St/Falcon Programs
- - SND: Sun, NeXT, Mac
- - WAV: PC
- - Raw data: Raw data for many programs
-
- "Data reduction"
-
- You can choose in which pack format the samples sould be exported. Basically
- the following formats are possible (not all are implemented in every case):
-
- - Keep: the sound data will not be changed.
- - 16 Bit Stereo: save in 2 channels with 16 Bit each.
- - 16 Bit deltapack: save as logarithmic compressed data, that needs 50%
- less memory but sounds nearly like 16 Bit.
- - 16 Bit µ-LAW: Only needs 8 Bit, sounds better than 8 Bit, but worse than
- deltapack. Used on Sun and NeXT.
- - 8 Bit Stereo
- - 16 Bit Mono: if stereo data should be saved as mono, both channels are
- added together.
- - 16 Bit Mono deltapack
- - 16 Bit Mono µ-LAW
- - 8 Bit Mono: Better use deltapack!
-
- Notice that it is almost useless to convert a worse format to a better one.
- It only requires more memory but sounds the same. But it is possible that
- other programms support only some formats.
- Converting µ-LAW to deltapack can result in slightly worse sound quality,
- although deltapack is the better format.
- "Keep" does not always really keep the pack format because not every format
- is supported in every file format. In this case the sample will be converted
- to the next better pack format.
-
- Save options
-
- When saving samples, 525 can maximize the volume of the sample.
-
- You can select a fade in/out effect, too, which ranges over the first and
- last 0.2 seconds of the selected part of the sample. You should use this
- effect only once with the same sample. This effect can not be heard until
- the sample is saved and reloaded.
-
- "Export" converts the sample. A file select box will be opened to enter
- the destination file name.
-
- If import and export sample have the same name, a temporary file will be
- created on the harddisk. Therefore it is possible that the data could not be
- saved even if there should be enough space on the disk.
-
-
- File/Quit
-
- Terminates the program.
-
-
-
- 4. Internals
-
- One supported sample format is the DVSM-Format of the programs "WINREC" and
- "FORTUNE". Those are programs for the ATARI FALCON.
-
- A DVSM sample file has the following structure:
-
- typedef struct
- {
- char magic[6]; /* "DVSM" */
- int headlen; /* Headlen in Bytes*/
- int freq; /* Sample freqency 0=8kHz 7=50kHz*/
- char pack; /* 0 unpacked, 2=DVS packmethod (not yet supported)*/
- char mode; /* 0=Stereo 8Bit,1=Stereo 16Bit,2=Mono 8Bit*/
- long blocklen; /* if pack=1: Length of a packed block*/
- } DVSMHEAD;
-
- followed by the 16 Bit stereo data (or DVS 8 Bit data).
-
- The sample frequencies 0 to 7 correspond to the following frequencies:
- sam_freq[8]={8195,9834,12292,16490,20770,24585,33880,49170};
- For further information refer to the WinRec documentation.
