Hello there! People of the Audio Digital Processing..
I have a big problem!!! Jejeje. No. I have a problem. I want to work in
ProAudio, and my question is, DSP or FPGA?

My idea is to improve the Audio Quality in several aplicattions. I have to
work with THD, SNR and DA/AD Converters. I don't know if the FPGA works for
these parameters..

Someone can help me?

Vielen Dank!

Hello Ariel,

That seems to be a typical application of a DSP; floating point is nowadays=
 the standard for Pro Audio applications. The nicest family would be a SHAR=
C from ADI, although you also have TI's C67x. On the other hand, you can al=
so do it on an FPGA, but in such a case you will not be dealing with the im=
plementation the algorithms in Software, but in Hardware instead.

This is a tradeoff between maximum flexibility (FPGA) and ease of use / max=
imum productivity (DSP). For instance, if you need to connect different dig=
ital audio streams in rather weird manners, it would be worth going the FPG=
A path, provided that you already have much knowledge of how to implement y=
our Signal Processing algorithms in the FPGA fabric. Enven in such a case, =
a smaller FPGA or even a CPLD plus a decent DSP would do the job in a more =
efficient and easier manner.

BTW, from your name I infer that you could be a spanish speaking guy, but f=
rom your "Thank you" it seems like you are located in Germany, kind of
my s=
ituation nowadays. If you want, send me a private email and we can further =
discuss.

Regards.

Hi, 
I agree. DSP is a good choice.
However, a FPGA's manufacturer doesn't think the same way:

I'm spanish speaker too. If you both want, contact me.

I think in most cases, a DSP will be the best choice. We make a SHARC 
21369 & Cyclone III FPGA module that lets you do both. Checkout our 
website if interested.
