dsp2hps

I heavily reworked MeleeHps to be way more user friendly and produce slightly better results
seriously, it now literally takes 5 seconds to go from audiofile.anyformat to audiofile.hps

How do I use this?

vids:

• normal loops
• custom loops

normal loops:

1. drag your audio file onto 'normal_stereo.bat'
2. that's it.
3. you can also invoke from the command line: normal_stereo.bat myaudiofile.ogg

custom loops:

1. set the --loop_point parameter in 'custom_stereo.bat' and save
2. drag your audio file onto 'custom_stereo.bat'
3. that's it.

mono sources:

1. use 'normal_mono.bat' and 'custom_mono.bat' instead

That's so easy! What's the catch??

• you still have to make sure your source audio file loops correctly

MSVCP140.dll

If you see an error message about MSVCP140.dll, download and install Visual C++ Redistributable for Visual Studio 2015 (x86). Make sure you get x86 and not x64.

How to build

You need:

• Visual Studio 2015 (or compatible version? I used 2015)
• an installation of boost

You have to set up Visual Studio to include and link to boost as described in the getting started link.

What are you working on next?

• rewriting all the main.asm + assembler business in an actual programming language to make the world a little more sane
• further parameterizing so you'll be able to drag all the files onto run.bat and convert all of them in one go
• writing hist1 and hist2 in the HSP headers correctly to remove popping all together
• Adding support for custom loops (loop points at any arbitrary sample, not just block boundaries)

Historical Changelog

changelog v2 (2016/04/01):

• you can convert files in batch! Just drag them all onto run.bat

changelog v1 (2016/03/31):

• no more opening with audacity and clicking and saving to format the file correctly
• no more fiddling with hex editors
• no more copy pasting samples-this and blocks-that
• drag-and-drop or invoke from the command line
• more accurate block headers mean fewer/smaller pops during playback
• parameterized output file names let you do a bunch in a row without overwriting your output

How'd you do it??? (technical details)

• audacity i included ffmpeg, which can convert from any format to 16bit WAV 32000 kHz from the command line

• hex editors dsp2hps automatically adds the correct padding. I discovered that DSP data must be 32-byte aligned! 16-byte alignment also seemed to work for me, but all the stock HSPs are 32-byte aligned. This must be why achilles sometimes found that adding a pad in a hex editor didn't always work the first time.

• samples/blocks well simply, that data is all calculable from the DSP files themselves.

• drag and drop the whole conversion process can be done in one batch script

• more accurate block headers the original MeleeHps used the first block header in the file for every single block. dsp2hps writes every block header 100% correctly, including the hist1 and hist2 values that require decoding the DSP block to set correctly. This completely eliminates the auditory pops common with the original MeleeHps. I included the most complete documentation I could assemble for the format of HSP audio files in the code

• output file names just a small quality of life edit. the output file now has the format [inputfilename].hps, so songname.mp3 would produce songname.mp3.hps as the output. This means you can run a bunch in a row and move out all your hps files once you're done
