Digitalsound toolchain/demo from wav 2 Oric

Post by waskol » Sat Nov 30, 2019 9:25 pm

I used for this a few tools from the ZX community, namely :
- sox.exe
- Sam2ay.exe
both extracted from wav2ay_src (you can find it here : http://www.worldofspectrum.org/pub/sinclair/tools/pc/ )

I used "digit.s" from dbug in its welcome sample little demo as a player.

look at the osdk_buid.bat to see how the sample.wav is converted to a sample.s file

Code: Select all

::
:: Converting from WAV to RAW...
::
echo Converting from WAV to RAW...
.\tools\sox sample.wav -r 11025 -b -u -c1 Output.raw


:: Converting from RAW to AY
::
echo Converting from RAW to AY
.\tools\sam2ay.exe

%OSDK%\bin\bin2txt -s1 -f2 -n16 Output.ay sample.s _Sample
I did this because It took me a lot of time to find a way to digitalize some .wav samples into Oric/AY8912, and it can be usefull to anyone.

The result quality depends on the original wav sample, and it is far from perfect but a good start to do better.

Is this sam2ay doing things very different from what my SampleTweaker.exe does?

I used that for my Oric Tech demo:

Code: Select all

SET SAMPLETWEAKER=%OSDK%\Bin\SampleTweaker.exe

%SAMPLETWEAKER% data\Sample.raw build\files\BoomTschak.raw
%SAMPLETWEAKER% data\SampleDefence.raw build\files\SampleDefence.raw
%SAMPLETWEAKER% data\SampleForce.raw build\files\SampleForce.raw
%SAMPLETWEAKER% data\SampleHa.raw build\files\SampleHa.raw
%SAMPLETWEAKER% data\SampleYeah.raw build\files\SampleYeah.raw
%SAMPLETWEAKER% data\SampleChimeLoopStart.raw build\files\SampleChimeLoopStart.raw
%SAMPLETWEAKER% data\SampleChimeLoopEnd.raw build\files\SampleChimeLoopEnd.raw
%SAMPLETWEAKER% data\SampleMusicNonStop.raw build\files\SampleMusicNonStop.raw
%SAMPLETWEAKER% data\SampleTechnoPop.raw build\files\SampleTechnoPop.raw

I missed your tool and I don't know why (I discover it !) !

Originally, sam2ay is just a littl pearl routine thatconvert 8-bit unsigned sample to AY volume levels

so, Is this sam2ay doing things very different from what my SampleTweaker.exe does? I don't know

Code: Select all

#!/usr/bin/perl -w
# convert 8-bit unsigned sample to AY levels

binmode STDIN;
binmode STDOUT;
while (!eof(STDIN)) {
	read(STDIN, $b, 1);
	$b = ord($b);
	if ($b < 2) {$lo = 0;}
	elsif ($b < 5) {$lo = 1;}
	elsif ($b < 7) {$lo = 2;}
	elsif ($b < 10) {$lo = 3;}
	elsif ($b < 14) {$lo = 4;}
	elsif ($b < 19) {$lo = 5;}
	elsif ($b < 29) {$lo = 6;}
	elsif ($b < 40) {$lo = 7;}
	elsif ($b < 56) {$lo = 8;}
	elsif ($b < 80) {$lo = 9;}
	elsif ($b < 103) {$lo = 10;}
	elsif ($b < 131) {$lo = 11;}
	elsif ($b < 161) {$lo = 12;}
	elsif ($b < 197) {$lo = 13;}
	elsif ($b < 236) {$lo = 14;}
	else {$lo = 15;}

	read(STDIN, $b, 1);
	$b = ord($b);
	if ($b < 2) {$hi = 0;}
	elsif ($b < 5) {$hi = 1;}
	elsif ($b < 7) {$hi = 2;}
	elsif ($b < 10) {$hi = 3;}
	elsif ($b < 14) {$hi = 4;}
	elsif ($b < 19) {$hi = 5;}
	elsif ($b < 29) {$hi = 6;}
	elsif ($b < 40) {$hi = 7;}
	elsif ($b < 56) {$hi = 8;}
	elsif ($b < 80) {$hi = 9;}
	elsif ($b < 103) {$hi = 10;}
	elsif ($b < 131) {$hi = 11;}
	elsif ($b < 161) {$hi = 12;}
	elsif ($b < 197) {$hi = 13;}
	elsif ($b < 236) {$hi = 14;}
	else {$hi = 15;}
	
	print chr(($hi << 4) + $lo);
}
