I know WAV files are large, and MP3s are smaller, but I was wondering what is the smallest sound file that keeps quality and can be used in DBPro?

Sorry, I did write out a huge post here detailing all my thoughts, but when I clicked submit, the page didn't load properly. So I pressed the Back button to try again, but with this forum being as crap as it is, it forced the page to reload ... so I lost everything I spent half an hour typing.

But summing up:
Stick with 16bit 22000khz mono WAV files. Standard WAVs. There are a bunch of compression techniques for WAVs like ADPCM, IMA and 8bit Au-Law etc, which we all have the codecs for cos they come with windows, but they're not supported. You cant use MP3 for sound files, as far as I am aware - only music files, which will probably restrict you to 1 music file being played at a time, and you wont be able to set music speed.

So:
16 bit, mono, 44khz isn't necessary, as it's only a bit better than ..
16 bit, mono, 22khz. Should be ideal.
8 bit, mono, 22khz at a push, is the smallest of the lot. The jump from 8bit to 16bit isn't noticable for certain sounds, and is for others. Might have to experiment with that one.

Hope that helps ... and I hope I dont lose this post too.

Insiiiiiiiiiiiiiiiiiiiiiiiide!

Keep with 16bit wavs for sound quality - dropping to 8bit lowers the quality of the sound dramatically. As for the sample rate - I just learned today that the sample rate(44,100, 22,050 etc) is the sound speed that DB uses for the set sound speed command. Its useful knowing this when speeding/slowing sounds.

Id advise you listen to fallout - he seems to be the badboy with sound and music in these parts.

i thought DBP could use MP3s as sound files. i just tried it and it didn't work. then i tried it in DB1. strangely, DB1 can use MP3s as sounds but no DBP. kinda stupid if you ask me.

also why isn't this on the DBP board?

stop looking at me!

Ahh, tis a common misconception that 8 bit is much worse than 16 bit, I assure you. By far the key player is sample rate. The only time 8 bit causes problems is for certain types of sound with very consistent dynamics with subtle changes (gentle music or very quiet, low sound effects etc). For speech and most sounds, the difference between 8 bit and 16 bit is pretty much unnoticable.

Check this out:

Same sample taken from Severance - 16 bit original and one I converted to 8 bit. You can't tell the difference. The secret is not to use and dither options, as then you get that background hissing. But in essense here you have two sound samples that are of the same quality, but one is half the size and db can play both!

Insiiiiiiiiiiiiiiiiiiiiiiiide!

Ah

I feel your pain by the way. That happened to me yesterday.

On Opera at least, however, the text is saved using the back and forward buttons. You should move on from that antique Internet Explorer technology!

The forums are slow even for broadband. I do like them tho.

My guess is these boards are being run on MYSQL. Which is good for smaller boards, but not for large boards. I would move it to Sql Server 2k. Faster, more reliable, and friendly to dial up users.

Then again it could be the host for these boards to.

Err but thanks for all you information, I will use wavs and find a decent compression for them.
