Saturn PCM <-> WAVE converter!

RockinB - Jan 19, 2003

			Hello guys! I've analyzed the differences between the SEGA Saturn .PCM format and the PC .WAV format. Now here's a beta win9x version of the SEGA Saturn wavetools: The Rockin'-B news... There are two ways of usage: You got .PCM or .SND files from Saturn game CD's and want to hear it on PC. Or you're making a homebrew Saturn game and want to include custom sounds created on PC. Mind that this is a beta version. But there is only one file that I know of that makes problems. What's your opinion? Bye, The Rockin'-B

			Thanks. This will certainly help me... if I manage to extract your .rar. For now, it gives me a crc error.

			You need WinRAR at least version 2.9 to extract. If the CRC32 of "SSwavetools_win9x_beta1.rar" you're getting is FAA02175, then the file should extract fine.

			I've finaly tested your converter on a wav file. It seems to work well. The .h you output is a int array (-128,128, as I can see), whereas I did expect a char[]. Does it matter, or are you sure char and int are the same ? What about that file that makes problems ? Did you test with a snd file and a saturn ? In this case, could you put the loading code somewhere (I know it is not hard, but if it's already done) ? Thanks for your soft, anyway

			int and char are the same...that is, as long as int is a single byte the only difference is in how you interpret the value: as a number, or as an ASCII code. BTW, the correct range for signed bytes is -128 to 127.

			@vreuzon: The .h file is OK, the compiler would have shown an error if it wasn't(values bigger 127). As for loading .PCM or .SND files on Saturn, I have only tried to play sounds that where included into the binary(that's what the .h files are for). Using the SGL sample sound program it worked, but I haven't played around with the pitch settings, you have to do so for yourself. If you got a clue how the pitch value is related to the .wav values(samplerate or what), let me hear. And concerning .snd files: they are a concatenation of .pcm sounds. So if you're going to make a game and you're sure what sounds you use in a level, then you put all that sound together in one .snd file. You will only have to load one file once, instead of several files again and again. Sound loading code: search the boards, there was a discussion of someone who wasn't sure if to put the sound files into main memory or sound memory. Maybe you can find code there. Bye, Rockin'-B
