Looking for sound card with specific requirements

post #1 of 4
Thread Starter 
Hi all,

I am looking for a sound card with (at least) two features:

- it needs to be able to transmit a 3 Hz wave (so no build-in high-pass filter).
- it needs to be possible to turn OFF the dc offset cancellation.

In other words, I want to transmit a 3 Hz wave with a dc offset, using a sound card.
Does anyone know a model that can do this?

Many thanks in advance,
Benedikt

I am not sure about the 3hz thing, but you should be able to add the DC offset with a power source if require(you may need a cap to keep it from flowing back into the sound card depending on its design.).

Thanks Nukemaster! Good idea. I'll give it a try.

What are you doing with this card anyway? Very few systems(that a user connects to a computer) go down to 3hz.

opamp output stages on many cards should have no issues going down to DC(0hz), but I have no clue what the dac/codec feeds them.
