I'd like to add playback to my audio decoding program..

[Austin Forgotten]

Hi there,

Well this is my 1st post here, since I'm stuck trying to figure out how to playback decoded dd/dts samples from my app (Tranzcode). I'm using C, and wanted to inplement BASS lib (www.un4seen.com) since I thought it would be easy to do, but after 3 weeks and no sounds coming from my speakers I'm crying out for help. I looked at DirectX and there are almost no examples of using the CreateFromMemory() function. I'm just a hobby programmer, not a pro so I need examples to get me up and running. Almost all examples are reading from file. BASS lib has a BASS StreamCreate() function which works with a STREAMPROC Callback, and I don't know how to get that to work either.

Does anyone know of a free windows audio lib or has some C code available to help me add playback to my program? Also it needs to be able to playback multichannel [i.e. 6-ch (5.1) and 32 bit floating point samples]. If I can't do it I may need to farm out the job to someone more capable :)

Thanks.

Well after trying for 3 weeks, then finally cry out for help, I managed to figure out how to do it a few hours after posting for help here, go figure!

I don't want to bore you with all the details, but if your interested I had started a thread at Ian Luck's BASS Lib forum, here:

I also prepared a simple working console program written in c which uses the function call I mentioned above, where I can finally copy my decoded samples into the playback stream.

You can download the source here (as the thread above also has the link)

You will need to download the BASS LIB v2.3 package at:

..and unzip it. Place my source into the "\c" dir and it should compile just fine.
