But I think it's a big difference in signal quality. There's no IQ imbalance due to L/R audio channel differences, no disturbed analog audio frequency response between dongle and PC. And I suppose in audio you have a spectral gap in the audio bass/LF region, a gap near the baseband center frequency. This is far more than just a single FFT bin (DC offset) in direct conversion receivers. > If it implements the USB Audio Class, its a USB Audio device. A headset > works the same. That's the nice thing about abstract interfaces. Yes, I think it's a nice abstract interface. Do you know the theoretical limits for the sample rate? Can it fill the full USB bandwidth or does it only accept "standard audio" sample rates?
