- SCONVERT, Version 1.11
-
- This program will compress or expand digital sound samples, and
- will convert from one format type to another.
-
- The program is copyright (c) Chris J. Flint, but may be
- distributed freely in the Public Domain.
-
- The sound samples supported are:
-
- ST Replay Versions 1. to 4. (*.SPL)
- Replay Professional (8 bit) (*.SPL or *.AVR)
- Master Sound (*.SAM)
- Stos Maestro (*.SAM)
-
- All of the frequencies supported by each sampler are supported by
- the program. A sample may be selected and resaved in any format
- and any frequency.
-
- Version 1.11 includes full support for loading and saving Replay
- AVR (8 bit) format files, including looping and note assignment
- data.
-
- For technical reasons there are slight differences in the
- frequencies used by ST Replay versions 1. to 4. (5, 7.5, 10, 15,
- 20, 30, 40, & 50 kHz) and the new Replay Professional software
- (5.5, 8, 11, 16, 22, 32, 44,& 48 kHz). Replay 5 is also likely to
- work with the same set of frequencies as Replay Pro, and is
- therefore supported by this program.
-
- This program will also support any frequency used by Stos Maestro
- (any integer between 5 and 32kHz), or Master Sound (5, 7.5, 10,
- 15, & 20 kHz).
-
- COMPRESSING A SAMPLE
- --------------------
-
- When compressing a sample, the program will use oversampling
- techniques. Instead of throwing away some bytes and saving
- others, the program will average the data. For example, if a
- sample is being compressed from 20kHz to 10kHz, the program will
- save the average of every pair of bytes. This will provide a more
- acurate representation of the signal than discarding alternate
- bytes, or sampleing at 10kHz.
-
- EXPANDING A SAMPLE
- ------------------
-
- When expanding a sample, the program will interpolate the data,
- and calculate the value of each additional byte to be included
- in the output file. This will improve the quality of the output.
-
- OUTPUT FILE
- -----------
-
- The output file will be saved in the same directory as the
- source, and the filename will be the same as the source, but with
- the last letter changed, and appropriate extension as detailed
- below.
-
- Old Replay will be saved as *X.SPL
- New Replay will be saved as *Z.SPL
- Stos Maestro will be saved as *X.SAM
- Master Sound will be saved as *Z.SAM
- Replay (AVR) will be saved as *Z.AVR
-
- The original data file will not be altered.
-
- The program checks the save filename does not exist in order to
- prevent another file being overwritten.
-
- The program will only load a small amount of data into the
- machine at any one time, and therefore, the length of sample
- which may be converted is not restricted by machine memory, but
- by the space on the disk. If there is insufficient space, the
- program will display an appropriate message.
-
- If the data file is long, the conversion may take several
- minutes.
-
- USING THE PROGRAM
- -----------------
-
- The program will work in either medium or high resolution.
-
- To use the program, use the mouse to select the desired source
- and output formats, and frequencies. When selecting the Maestro
- output frequency, after clicking on the frequency option, it is
- necessary to type in the frequency from the keyboard followed by
- <RETURN>. The value may be any integer between 5 and 32 (kHz).
-
- Once the options are set, click on the START box to display the
- file selector. Double click on the source filename and the
- conversion will begin.
-
-
- I would like to thank "Two-Bit-Tony" for supplying the exact
- frequencies used by Replay and Master Sound, and for the
- demonstration of a pre release version of the Replay Professional
- Software. This suite of programs is one of the most exiting
- applications I have seen for the ST, and would recommend it to
- everyone who is interested in music.

- Includes an improved file selector for users of drives other
- than drive 'A', and a small modification to .AVR to .AVR
- conversion in order to retain the sample name contained in
- the header
