Finally here smile.gif This is a Beta release, there are things that I am not 100% happy with, but then I am apparently never happy with my code biggrin.gif

So, want a full featured, supported, DSP Sound Engine for your project? for free ?

Check it out http://www.u-235.co.uk/se/index.php

Feedback and bug reports welcome, I have a list of things to do on this as long as my arm already so keep checking back for new updates and releases.

Big huge thanks to the other guys of U-235 and also to the chaps of Reboot and Jagware, excellent help, ideas and hints throughout as well as some top laughs! Cheers guys.

Version 0.15 now released with some changes and improvements.

Now with selectable playback frequencies of 8,12,16,24 or 32 kHz!

PLEASE NOTE! Higher frequencies are more sensative to bus latency and will sound wrong if the main bus is being utilized by higher priority CPUs, this is a known bug that I am working to address.

Enjoy

10 points to the person who can find the obvious bug in release 0.15 first biggrin.gif

It's nothing major, so don't worry it's not like it's going to eat your face biggrin.gif

I have fixed this already but will hold on releasing update until I have fixed all the new bugs I have crafted into the build at the mo smile.gif

Version 0.16 released (changelog), mainly to resolve the embarising bug in the previous release as well as a few others. More still to go, I'll get them eventually biggrin.gif

I am making some significant changes to the SoundEngine interface, these should make for more intuitive API calls without you having to do any linkomaths before playing a sample! (I am porting the LinkoMaths into the RISC code).

What will this mean?
- The dropping of the periodXX lookup tables,
- The removal of some internal hackery,
- More accurate module pitch bends and slides,
- Removing the dependancy of mod parsing code on specific SE commands
- The removal of those SE commands completely
- Being able to simply specify a sample frequency to play at to the API and it doing the hard work for you!

The future? These are just ideas I have that this change will potentially make possible, how feasible they are I won't know right now, but
- The ability to switch to a new playback rate whilst the engine is running without (hopefully) any/much distortion to active audio
- Dynamic adaptive playback adjustments! (this one is likely a way off and possibly a pipe dream, but I think possible...)

Once I have completed this chunk of work I should hopefully be able to complete more of the missing mod parser effects. 2012 is going to be busy biggrin.gif

OK, looks like I may have stuffed up the release of 0.17 somehow :/ I will confirm and rectify as needed when I get home. Sorry about this.. I'll post again when I have an update..

OK, more on this.. I haven't stuffed the release of 0.17! YAY! It seems I have possibly tickled a bug in SLN!

For my test I have assembled main.o with madmac.

I have then linked with ALN, and also linked a version with SLN using the same binary blobs (main.o and dsp.o) which were produced by MAC.

The output from ALN works as intended, the output from SLN doesn't. I think SLN is introducing an alignment issue within the DSP code.

Music is good for you !!

Now you can select between SebRmv player and Linkovitch's one. That's a very good think, two very good free module players. No excuse for don't including music in your games. Except Fadest who got a good excuse (Private joke !)

Bah... The Jag is like the Lynx : mp3 compliant ohmy.gif

Btw, I have an even better excuse, I'm overbooked right now and have no time and no will to take some time to code sad.gif
But congrats to you Linko for doing this great (but futile biggrin.gif) sound engine.
