Amiga sound playback routine/format questions
« on: August 09, 2010, 08:39:12 PM »
A couple of questions,

Firstly, is there a routine for Blitz Basic to playback 14bit audio via the channel muxxing hack of Paula? And if so does it strip out the extra data from a 16bit sample or do you have to create bespoke 14bit samples?

Secondly, as far as standard 8bit sample playback goes was there any kind of compression/decompression standard or do you have to read out the data uncompressed from memory due to lack of CPU time on OCS? (not expecting MP3 levels of compression! Just wondering if there is anything apart from depacking it from a compressed files to RAM as raw data before playback)

All questions are centred around a bog standard 7mhz OCS/ECS motherboard.

Cheers.

Ahh right wasn't sure if Octamed does the 14bit trick on stock machines. And yes I was thinking Blitz calling a 68k ASM routine :)

At most an anim 5/7 may be playing at the same time, possibly just a static ham6 picture slideshow....not really decided as wasn't even sure it was possible.
