PCM Ring Buffer, Psuedo Streaming.

[ahenry3068]

NOTE: ZCM is a the "Native" PCM file format for ZSMKIT, it's similiar to a WAV file but not quite the same

I've posted another Demo of this technique in DEMOSCENE viewtopic.php?t=7320
The code there is actually an update of this code.


I've written some code that can manage a ring buffer and load and play a bunch of ZCM's sequentially and seamlessly.
It's not quite the same as streaming a large file from Disk but you get the same effect. I've included a nice little background too.

Included in the SOUNDS/AMBIENCE/ Directory is all the ZCM files as well as the source .RAW file I split up and the QB64 program I used to split it. (Zerobytes raw2zcm must be in your path for the QB64 program to work properly)

To end the Demo just hit ESC. There is 21 minutes of seamless audio if you leave it play through (after which it starts over).

(The only limit with this approach is the amount of disk space available, A 3 hr or even a 10 or more hour sound track is possible).
