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.

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.

On the other hand, you can also do it on an FPGA, but in such a case you will not be dealing with the implementation the algorithms in Software, but in Hardware instead.

This is a tradeoff between maximum flexibility (FPGA) and ease of use / maximum productivity (DSP). For instance, if you need to connect different digital audio streams in rather weird manners, it would be worth going the FPGA path, provided that you already have much knowledge of how to implement your 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 from your "Thank you" it seems like you are located in Germany, kind of
my situation nowadays. If you want, send me a private email and we can further discuss.

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 SHARC from ADI, although you also have TI's C67x. On the other hand, you can also do it on an FPGA, but in such a case you will not be dealing with the implementation the algorithms in Software, but in Hardware instead.

This is a tradeoff between maximum flexibility (FPGA) and ease of use / maximum productivity (DSP). For instance, if you need to connect different digital audio streams in rather weird manners, it would be worth going the FPGA path, provided that you already have much knowledge of how to implement your 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 from your "Thank you" it seems like you are located in Germany, kind of my situation nowadays. If you want, send me a private email and we can further discuss.

Subject: [audiodsp] FPGA or DSP

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!
