ANN: article on Ada language for audio applications

[Gustavo Hoffmann]

Hello,

I'm just sharing an article on Ada language for audio applications that I've co-authored:

Thanks,

Gustavo Hoffmann.

Hello Gustavo,

Very nice to read and documented text on an original subject concerning Ada on DSP.
Have you considered to go further to formal proof with SPARK?

Thanks, Pascal.

That's an excellent read -- thank you for posting it.

PS -- You wouldn't happen to be able to make the code publicly available, would you?

Thanks!

Yes, I have considered that. Unfortunately, due to time-constraints, I was not able to work on it. In general, formal proof of numerical algorithms is an interesting topic.

Thanks for your interest! 

The original source-code of the Layer-2 decoder is closed-source software. Therefore, I'm not allowed to publish the source-code of the ported implementation. 

However, you can find the implementation of the biquad filter (which is completely unrelated to the Layer-2 decoder) in the article...

You're quite welcome!

That's somewhat disappointing, the description in the article made it sound like generics were taken advantage of in a good way and I was interested in seeing that in particular.

I'll take another look at that.
Thank you for your reply.

I really appreciated the article and I learned a lot from it. I really liked the detailed comparison with C and C++. Thx.
