Hi,
has anyone extended Squeaks methods for reading and writing wav files so they can handle 24 bit integer and 32 bit float audio samples? I'm aware of AbstractSound's capabilities re wav files. Thanks, Herbert |
Hello Herbert
Did you check the Cuis and Pharo implementation? Is it the same?

Hi Hannes,
I checked Cuis before asking as Juan is (has been??) into Audio. Only 16 Bit. Pharo have stripped it. Cheers, Herbert Am 04.03.2013 03:58, schrieb H.

OK, Herbert
And what about http://www.krestianstvo.org/index_en.html or open croquet for example? krestianstvo has a one-click image download (100MB) with everything included to set up a virtual environment server. There is a slight hope that maybe they have an updated WAV file format library? And where is the WAV spec for 24bit integer and 32bit float samples? It could be that it is not all that a big effort to add this to the existing Squeak 4.5 Helpful as well is to identify open source implementations in other languages. --Hannes On 3/4/13, Herbert König <[hidden email]> wrote: > Hi Hannes, > > I checked Cuis before asking as Juan is (has been??) into Audio.

Hello,
On Mon, Mar 4, 2013 at 10:48 PM, H. Hirzel <[hidden email]> wrote: OK, Herbert The latest Krestianstvo is based on the OpenQwaq (Squeak 4.1 derived) image, and does not introduce any new low-level audio library yet. But, as it is OpenQwaq/Croquet based, it has OpenAL support by default, where you could find a lot of low-level stuff that work with audio. So, you could try any of Croquet family images for OpenAL coding. Another audio library to try is a QuickTime library from OpenSophie project (existed Squeak repository http://www.squeaksource.com/SophieGoldDig.html). The official project site seems to be down, where the developer image was available for a long time. Regards, Nikolay And where is the WAV spec for 24bit integer and 32bit float samples? |
