    Upper limit of frequency response of $150 or so sound interfaces?

    Was hoping to find that info before I buy :)

    Upper limit of frequency response of $150 or so sound interfaces?

    How do we find out if it has analog filtering in place that will negatively affect bandwidth?

    Upper limit of frequency response of $150 or so sound interfaces?

    Cosmos looks interesting, but it doesn’t have A DAC to match. Many of the things I’d like to do, it would be helpful to have a signal generator in addition to signal capture by the device.

    Upper limit of frequency response of $150 or so sound interfaces?

    That amount of noise probably won’t bother me, and useful frequency range to 70khz with noise below -100db is still better than useful range to only 22khz. I realize there are tradeoffs between absolute accuracy, noise floor, upper and lower frequency limits and cost.

    Upper limit of frequency response of $150 or so sound interfaces?

    I’m interested in measuring frequency response, distortion, etc of signals from dc to 100kHz or so with a spectrum analyzer, and digital oscilloscope, and wondering where to find upper and lower frequency limits of various USB audio interfaces. I’d like a little more range dynamic range than my...
