Using Line-In on Sound Card for Measurement/Analysis

[Shawnzyoo]

I have been reading up using the Line-in on my computers sound card and the pogram XOSCOPE to be able to do some various measurement/analyzing
But before I attempt to actually plug anything together i want to make sure I don't wreck my soundcard
I have found that some soundcards have the line-in listed at a voltage of 1.737 (peak) is this the standard for soundcards?
has anyone here have any experiences with this setup
successes/failures?
Thanks for any advice!

Usually 2V peak-to-peak isn't a problem. It's almost assuredly going through an input transformer first anyway. It's hard to wreck it.

Using the Line-in on a sound card for measurement and analysis is a common and cost-effective method for many users. It allows for easy access to the audio signal and can provide accurate measurements with the right software and equipment. However, it is important to take precautions and ensure that you do not damage your sound card in the process.

Firstly, it is important to check the specifications of your sound card to determine the maximum voltage that it can handle on the line-in. While some sound cards may have a standard voltage of 1.737 peak, it is always best to double-check and ensure that your sound card can handle the voltage that you will be inputting.

It is also recommended to use a buffer or attenuator between the audio source and the sound card to protect against any potential voltage spikes or surges. This will help to prevent any damage to your sound card.

As for experiences with this setup, it would be best to reach out to others who have used the same setup and ask for their feedback and advice. This can help you to avoid any potential pitfalls and ensure a successful setup.

In conclusion, using the Line-in on a sound card for measurement and analysis can be a useful and cost-effective method, but it is important to take precautions and ensure that your sound card is not damaged in the process. Double-check the specifications of your sound card and use a buffer or attenuator for added protection. It would also be beneficial to seek advice from others who have experience with this setup.
