Hi Phil, I did that using Ronie's OpenAL binding and Merwann's wav parser back in 2014-2015: MCSmalltalkhubRepository owner: 'ronsaldo' project: 'OpenAL' MCSmalltalkhubRepository owner: 'MerwanOuddane' project: 'WAVParser' I did things such as (build yourself something derived from this code I did not check if it works): MyClass>>example WAVParser wavFromStream: ('resources/music/spellNoise.wav' asFileReference readStream binary readStream). contextAttributes := ALContextAttributes new. device := OpenALC openDefaultDevice. context := device createContext: contextAttributes asList. context process. context currentDuring: [ "Create the buffer" buffer := self makeBufferFromHeader: wav header data: wav data asByteArray. "Create the source" source := OpenAL genSource. OpenAL sourcei: source param: AL_BUFFER value: buffer. "Play the source" OpenAL sourcePlay: source. "Play for sometime " (Delay forSeconds: wav header soundDuration) wait. "Delete the source and the buffer" OpenAL deleteSource: source; deleteBuffer: buffer ]. OpenALC nullCurrentContext. context destroy. device close. MyClass>>makeBufferFromHeader: header data: data | buffer | buffer := OpenAL genBuffer. OpenAL bufferData: buffer format: (self readFormatFromHeader: header) data: data size: data size freq: header sampleRate. ^ buffer MyClass>>readFormatFromHeader: header ^ header channels = 1 ifTrue: [ header bitsPerSample = 8 ifTrue: [ AL_FORMAT_MONO8 ] ifFalse: [ AL_FORMAT_MONO16 ] ] ifFalse: [ header bitsPerSample = 8 ifTrue: [ AL_FORMAT_STEREO8 ] ifFalse: [ AL_FORMAT_STEREO16 ] ] I am pretty sure with a little work those things could work again. I have never succeeded in playing mp3 files from Pharo though (but I'm on mac and I remembered trying solutions that did not work on Mac but may work on other OS). Have fun guys :-) On Sat, Oct 14, 2017 at 10:01 AM, phil@highoctane.be <phil@highoctane.be> wrote:
I'd like to do something like this: https://www.youtube.com/ watch?v=vL7D4eU0lYE
to showcase FFI, Bloc, and the Pharo liveliness.
And once I get the basics working, level up in getting it working in a VR headset.
Is there anyone having a binding to a library for dealing with the sound part, like FMod or other things like that?
I see this as a medium term project, so, like I can get it working by the end of the year.
TIA
